These are the fibre/epoxy parts supplied in the part kit from MR, they are light and of good quality

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom_2-_002.jpg)

The wood parts are here CNC cut and the formers need only minor trimming to fit, the wing ribs will have to be binned though as the root rib does not match the root section of the fuselage, I finished up binning all the ribs on the last Venom and starting from scratch and I will do the same this time as there is a turned down section at the trailing edge on some of the ribs that I have no idea about and is not mentioned on the plans and is not some alignment guide either. Luckily I made templates of the "new" ribs to aid a friend who was also going to build one so I shall use these.

Here is the intake now glued up ready to fit inside the fuselage

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom_2-_004.jpg)

Heres the intake in place before the front former is fitted

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom_2-_006.jpg)

And lastly for tonight, the formers in place, initially tacked with rapid araldite and then when checked the last time for accurate alignment, Hysol glue applied.

The next job will be the noseleg mounting plate.

Post by: IB on February 26, 2006, 13:42:00 PM
I spent a little time marking the the fuselage for the noseleg mounting plate as the position for the plate is dependant on the type of retract used. The plans are drawn up for MR's own retract units which would be fine for the original model as this was a ducted fan weighing 16lbs, however, the turbine versions tend to weigh 22 - 28lbs so a meatier retact system is needed. I have got a set of Airpower units that Als Hobbies sell, I used the ones originally purchased for the Venom on my Boomerang XL and was very impressed by these units and at a reasonable price too so I have obtained another set. The supplied plate will not fit the new higher position so a new plate was cut and tacked into position as well as making the cutout for the front hatch, on the full size this hatch gives accesss to the battery, ballast and the rear of the instrument panel

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom_2-_009.jpg)

The plate in place tack glued in the interim

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom_2-_010.jpg)

I now highlighted the lines to cut along to remove the two undercarriage doors

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom_2-_011.jpg)

And removed said items

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom_2-_012.jpg)

This gives me access to the underside of the plate showing the alignment tabs I tacked on to ensure the plate stays in place whilst the glue sets, I will remove these tabs and apply Hysol top and bottom then apply some carbon fibre cloth and resin to stiffen the plate to the fuselage

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom_2-_013.jpg)

At the same time I will add some carbon cloth and tows to stiffen up the front fuselage areas, now to start the wings.

When the noseleg mounting plate glue had set I then added some carbon fibre cloth and resin to the top and bottom of the plate to firmly secure it and to stiffen up the nose area, whilst doing this I added the lower ply formet which lies just behind the nosebay, this also stiffens the front fuselage. A test run with the nose unit and strut in place confirmed the alignment was all correct

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom_2-_014.jpg)

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom_2-_015.jpg)

Whilst marking out the wing ribs I filled the gap between the inlet and ducting as the ducts are 1/8th - 1/4 inch larger than the inlet so this requires application of lightweight filler to make the inlets smooth and of scale appearance, its a little time consuming but worth it in the end and going around the applied filler before it set with a wet finger moulds it into almost the required shape.

Post by: IB on March 02, 2006, 22:08:41 PM
Hi Dave,

This is the second one I have built, I aquired the first part started but had to scrap what had been done ( one wing ). I found out about the boom alignment when I was doing the first, the ali tubes supplied pre cut to the angle required to make the tailplane parallel +/- with the wing should be cut to 13 degrees, however, they were cut to 17 degrees so I had to recut them. It is a builders (part) kit and MR has been accused of not giving enough detail in the plans but in fairness he has left it to the builder to construct it to suit their engine / radio / retract system, some find this not enough and are a little critical about these issues. Errors in the wing ribs which come CNC cut require these to be binned and a new accurate set to be cut. My first one flew straight off the board but on its eighth flight it went into failsafe three times, the last as I was setting it up for an emergency landing, and was totalled.
Engine is a JetCat P80 was the unit I used in the first one, more than enough power, once off the ground it flew on half power and full power was only used for verticals. I must admit though it looked superb in the air and flew on rails.

Nice job Ian. Note the comments about the Venom kit being short on detail and construction method left to the devices of the builder! The MR Hunter shares the same characteristics. Sorted out the retracks on the Hunter with a bit of judicious milling - the legs now sit on the retract block. Has the F18 flown yet?

Hi Barry

The f-18 has yet to maiden, I was going to take it up to Decembers Classic Jets but I had second thoughts and decided I would save it for a rainy day !

Andy, having to make up new wing ribs is no big issue once you know it has to be done, I find it an issue that the faults people have found and had to deal with have been brought to the manufacturers attention in the eight years that the kit has been available and nothing has been done to address these faults !

IB
Title: Re: DH Venom
Post by: IB on March 09, 2006, 20:52:36 PM
The wings have been started and the port wing is well on the way. Here, the primary structure has been pinned down and glued, each wing is built in one piece and after sheeting it is cut where the centre of the wing joining tubes are, the inner section is attatched to the fuselage leaving the outer panel removable for transport.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom_2-_17.jpg)
(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom_2-_18.jpg)

Once the glue is set the upper sheeting was added and left overnight, then the wing was flipped over and set on jigging blocks to ensure that while working on the underside it does not twist out of true as there is built in washout. Two servos are to be incorporated, one aileron servo in the outer panel and one flap servo in the inner panel inside the wheel well, these have to be added before the lower sheeting is applied. There is a third servo for the elevator rearward of the u/c plate but this is added after the sheeting is done. The jury is out as to whether I will have working airbrakes, I may just power these with mini air rams, they are not to be used in flight as the hinging area is minimal and they would just rip out, however, they need to be hinged as the wing tubes are set at an angle and when sliding the outer panel on the airbrake has to be moved up or it will catch otherwise.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom_2-_19.jpg)

And finally, here is my original Venom, I am going to do the same scheme as I liked it so much.

Will there be no problem fitting the Al's retracts, do they retract as per scale and are any mods necessary in the nose and wings. I am asking this as I am thinking of buying one.
Title: Re: DH Venom
Post by: IB on March 14, 2006, 22:19:46 PM
Hi Jetflyer

The Airpower retracts that Ali sells fit a treat, the mains are designed so the trunion block can be reversed, i.e. the leg retracts away from the cylinder, it requires one circlip to be removed then the block eased out and reversed then the circlip fitted back again. The main units have to be like this as the wheels are 4 inches diameter and the legs are short which means the wheels will foul on the cylinders, it does mean the cylinders will now sit inside the fuselage where it is convenient to fit the saddle tanks but I'm making up a set of custom fit one litre capacity tanks which have a recess that the air cy;inder will fit into thus maintaining maximum fuel capacity, a third tank sits forward of the air intakes giving a capacity in total of 3 litres.

The nose unit needs to sit higher in the fuselage than shown on the plan due to the difference in design to MRs own retracts. This is easily done, see the pictures above. One thing though and its not a problem, the unit retracts 90 degrees but due to the higher position in the fuselage it only needs to retract about 60 degrees for the wheel to be fully inside the fuselage, if the leg is allowed to go the full 90 degrees the wheel takes up valuable space where systems/batteries should go so I have fitted limiters to the unit so the uplock now is at approx 60 degrees. I'll do some photos for a better explanation in my next post. Hope this answers your questions.

Hi Jetflyer

Here are a couple of piccys regarding the u/c fit in the wing. The first is of the modified unit where I reversed the trunion block, you can see the circlip that has to be removed, the hinge pin is withdrawn and the block reversed.(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom_2-_022.jpg)

And here is the unit in the wing showing how much it protrudes into the fuselage, this is not a problem as the tank, as mentioned, will have a recess to allow for this without compromising capacity too much, 3 litres of fuel on a P80 equates to around 15 minutes of flight time at full throttle, more than enough.
(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom_2-_023.jpg)

And Phil, don't know who the gentleman is you are refering to, maybe you can shed a little light on his identity, but I got this from a friend last Christmas who saw it and thought of me, not sure whether to be flattered or insulted but it always makes me smile when I wander into the workshop
(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom_2-024.jpg)

Post by: siclick33 on March 20, 2006, 19:11:55 PM
Ian, are you using MR's own struts?

Are they inset into the retract? I'm a bit concerned that the MR struts may be too short if inset, as they look like they are designed to use a 6mm pin (or similar).

What are you using for a noseleg?


My kit has arrived and I'm going to start work soon. Overall I'm quite happy but a bit p**sed that the tail boom joiners are incorrect and the root rib is useless >:(. I haven't looked to see if I can use the rest of them yet. Mick told me to use the stock ribs otherwise I may have problems fitting the retracted gear in the wing. He said that the join would be covered by the cloth so isn't a problem; maybe not, if you don't mind having a huge step or a ton of filler!
Title: Re: DH Venom
Post by: IB on March 21, 2006, 20:51:24 PM
Hi S33
Yes, the struts are MRs ones for the Venom as is the noseleg which is a Eurokit one he's shortened a little, the main struts are 1/2 inch diameter which match perfectly the Airpower units as the clamp fitting is for a 1/2 inch oleo, they sit in the clamp to a depth of 20mm and as luck would have it are the correct length, although they are meant for a pin fitting into the MR unit they have a steel insert inside to give the cap screws threads some strength. I have just removed the cap screws and clamped them into the retract units. The noseleg has a brass insert fitted which I opened up to 6mm as the nose retract unit is a 6mm pin type fitting.

As there is a difference in design between the MR units and the Airpower units the height of the nose unit mounting plate is approx 1/2 inch higher than shown on the plan, see my above posts. I made up a new plate but you can use the supplied one but it will have to be cut into two lengthwise as the nose unit has to sit as far forward as possible leaving no meat on the front part of the plate, this isn't a problem to do though my replacement plates are longer than the one supplied I use the extra length to sit the batteries on.

I used MR's own Venom retracts in my original model and the cut outs in the two inboard ribs for the mounting plates were in the wrong place, this for units and ribs designed specifically for the Venom got me thinking what else is wrong, as a result I spent time going through all angles and incidences and found errors everywhere which I am quite happy to put into print, its a long list though but as the build progresses I will indicate these and the fixes. I will say throw the ribs away and start with a clean sheet, take a copy of the root section on the fuselage, and copy the tip birch ply rib onto balsa or Lite Ply, remove 3/32 inch from the top and bottom of this tip rib and this will give you the means to make a set of ribs using the sandwich method, once done make a copy of each rib for the other wing. Take the first two ribs R1 & R2 and offer up the u/c unit with strut attached and retracted, then make a mark on these ribs where the strut will lie 3/32 up from the lower edge of the rib, then mark where the mounting plate will be cut out, the upper part of the u/c uniy should be 1/8th below the upper wing sheeting and when the wheel is fitted part of the wheel should protrude through the upper wing sheeting, this of course will be covered up by the supplied fairing, it is the same with the full size. The new main wheels MR supplies are very good and are the correct scale thickness, I originally used Len Gardiner supplied wheels and fitted my own scale hub covers I turned up in perspex but these new wheels are spot on and harder wearing.

The wing joining tubes have to be parallel, they are not on the plan, 3 degree difference, if not parallel you will never separate the outer panel from the inner after building them, redraw the rear joiner on the plan in red as a reference.

The boom tubes have been chamfered to 17-18 degrees, these need to be reprofiled to 12-13 degrees, I made up a jig set at 13 degrees and recut them on my disk sander on my original model, I now will cut them to 12 degrees as I needed a tiny amount of down trim when I flew it so I figured to do away with the trim by reducing the incidence by 1 degree.

Hope this helps and dos'nt discourage you any, now knowing the pitfalls my second one is coming on in leaps and bounds, its going together faster than I can buy the additional items required for it !

Title: Re: DH Venom
Post by: IB on April 02, 2006, 21:40:09 PM
Managed to get a little more done over the last week, I'd prefer to have gone out flying but time off and decent weather are just not happening.

Both wings are now completed and joined to the fuselage, here is the underside of one inner and outer panel ready for the wing sheeting to be applied, the joining tubes have been triple checked to make sure they are exactly parallel, won't get the two apart if they're not, the plans are out by 3 degrees, sufficient to prevent separation as I found out on my first one !

The servos are in, aileron being obvious, the inner servo is for the outboard flap, there is an inner flap which is part of the fuselage pod, this will be done at a later date, but it makes life a lot easier to have the four flaps powered by four servos because using a "Matchbox" they can be accurately set individually to give the correct amount of movement each flap requires. Trying to balance one servo/two flaps is a pain.
(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom_2-_024.jpg)

The underside now sheeted with the aileron fitted, the cutouts have been made for the flap and airbrake.
(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom_2-_025.jpg)

Once both panels were completed they were glued to the fuselage pod one at a time, I used 5 min epoxy here, once both panels are set then the join will be reinforced with fibre glass top and bottom two inches either dide of the join.
(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom_2-_026.jpg)
(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom_2-029.jpg)

Once the glue had set it was time to dismantle the outer panels from the fuselage, they were left on for glueing so I could make sure both panels were true incidence wise and at the correct 2 degree dihedral. It is worth mentioning here that the angles on the fuselage pod for the dihedral are incorrect, they should both be at zero with 2 degress built into the root rib on each wing panel, however, the port wing root rib requires the aforementioned 2 degrees but the starboard root rib requires 0 degrees as the pod itself has the two degrees in, bit of a cock up there with the fuselage plug methinks, my last one was the same so all pods will have this error in.
(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom_2-_027.jpg)

And here on its lonesome is the removed port outer panel.
(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom_2-_028.jpg)

Next will be the tail booms and the tailplane but I'm off for a cup of tea and a bucket of wine gums.

I was sad to hear of the demise of your beautiful Venom and am following your new build with great interest. I very much miss my Venom and may follow your lead and build another given as you know the fantastic flying qualities which out weigh any building problems.....aren't they half the fun of modelling anyway! I think we have the same taste in aeroplanes as the F-18 is another favorite of mine..good luck with the test flight. I see you've gone for the scale hatch on the nose...I did this also with a removable cockpit rather than go for the v. large hatch...I did'nt like that idea much. Those retracts look good..... I used as you did Mick's own and found them a little weak (probably my landings!) The new wheels look good though

Keep up the building really enjoying the thread
Title: Re: DH Venom
Post by: siclick33 on April 04, 2006, 18:44:24 PM
Thanks for the continued thread. I think I would struggle to build this without your pictures.

I have just started sorting out the wing ribs. I have my template for the root rib. How did you make your rib set? I have heard about the sandwich method but never tried it.


I was just about to order Al's retracts but a couple of guys at my club have had problems. The complaints seem to be more about Al's help (or lack of) in replacing parts rather than the gear itself. I'm looking at Robart gear. I am also waiting to see what Unitracts can do.

Am I correct in saying that the 3/32 shout be taken off the root template? I am not sure why I would have to remove anything from the tip. Did you use the kit tip rib as a template for your new ribs, only it has the odd T.E. section on it and I don't want this to be transferred to my new rib set.

One final question for now. The plan calls for taper on the rear spar. Should this taper be made before the wing is built? i.e. does the packing amount stated on the plans take this taper into account. I don't want to get the washout wrong.

Dear Ian
Just a thought regarding the ribs.
If the wings were covered in pro skin instead of 1/8 or 3/32 balsa
would they then be correct. We had a similar problem with the ailerons
on the Lightning. The problem was the other way round it was because we used pro skin instead of 1/8 balsa.

Regards Phil G.
Title: Re: DH Venom
Post by: IB on April 06, 2006, 07:32:43 AM
3/32 inch off the root wing section top and bottom to account for the 3/32 inch sheet that will be applied, and use the birch ply full section tip rib that is supplied with the kit as your tip template, also taking 3/32 inch off this as well.

Phil, the Venom is pre-proskin, so 3/32 would have to be added to MR's ribs but the wing section at the fuselage differs from the root rib and subsequent ribs supplied with the kit, by the way, not impressed by proskin at all as a means to cover a wing. Its OK for flat uses such as a flap but I saw a Hunter covered in this stuff last year and it sagged between the ribs spoiling the superb scheme the plane had, give me balsa any day.

Thanks Ian, I hadn't seen the 'tip tank' rib as it was on a different sheet!

Could you help with my rear spar taper question? Do I taper it before or after assembling the wing? Do the packing amounts stated on the plan relate to the tapered spar? This is an area of concern for me as I don't want to get the washout wrong.
Title: Re: DH Venom
Post by: IB on April 11, 2006, 18:00:17 PM
Hi S33

The rear spars taper from 1/4 to 1/8 inch starting at rib 8 I think, remove the material from the 1/4 sq. strip so you are left with a tapering spar from rib 8's position. Then, take a sheet of 1/4 and cut a strip starting out at 6mm at the position of the root rib and finishing at 10mm at the tip rib, this is the packing you will put under the rear spar to achieve the washout required, 1/4 inch as measured at the trailing edge of the aileron, pin a spare length of 1/4 sq. under the front spar so the ribs are clear of the plan as they are of semi-symmetrical section.
When you pin down the rear spar, make sure you have the side with the removed material on the inside, the flat to the bottom.. Wax both spar supprts so they will not stick to the spars and you can use them again when you build the other wing !

Have been sidetracked recently due to work issues ( always a good excuse ) and repairing a model ARTF whose undercarriage mounts were just not up to the job, it had'nt seen any glue when it was constructed and the wood was the softest, nastiest that could have been used ! Therefore the Sbd u/c ripped out on a gentle landing taking the nose unit out with it. I'm not a happy bunny about that.  >:(

If anyone is interested I know a chap who is trying to sell a part built MR Venom kit. It is located in Aberdeen, but the logistics of getting it somewhere else is not too bad as we both live toward the Lincolnshire area and visit many shows. Asking in the region of £270 but open to offers!

If you are interested then pls email me at; steve@tsxonline.co.uk

Also, if anyone wnats graphics for theirs then come an see me at the above address (or www.tsxonline.co.uk (http://www.tsxonline.co.uk)) I will offer roundels and lettering to any design in a special 'Low tack' paint mask material for £25.00 Guarranteed crisp and clean results.

HI Ian,
It's been a long time since we've chatted.I finally flew my Venom in Bangkok the other day and it flew very well indeed.Unfortunately I did not get any piccys!(Too preoccupied)The only snag was the landing gear.It retracted fine but on landing the starboard main gear failed to extend.I think the Mick Reeves units are just not up to the task so they are coming out and are being replaced with units from PST.(pneumatic).No Damage,just a little scuffed paint on the tip tank.I'll be flying it again on the 16th and I'll try to post some pictures.It required some nose up trim and I think it may be a little nose heavy but it is balanced as per the plan.Did you have similar problems?The airplane came out quite light at 17 pounds ZFW and the PST 600 was more than enough grunt for it.I'll keep you posted,Cheers,John Vasil

Hi John

Nice to hear from you, long time eh? Glad you flew yours, I had eight flights with mine before I had an issue with three fail safe incidents in one flight culminating in a total write off. I am currently building another with different R/C gear and am using pneumatic units from Als Hobbies ( Jetpower Units ), these are good as I am using the same type in a Boomerang XL and they stand up to 32 lb landing weights fine. My Venom needed a couple of notches of down trim, this new one has the tail boom incidence reduced from 13 to 12 degrees to offset the trim issue, I'm currently sorting out a couple of other things but will be back onto the Venom build soon.

After a spring/summer that has taken me away from building due to other issues I am back now in a position to carry on.

After joining on the wing inner panels to the fuselage I reinforced the join with 4 inch wide glass cloth top and bottom, this is more than sufficient to give a really strong attachment.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/venom_2_029.jpg)

I now made up the tail booms, it was the intention by MR to use the wing and tail boom tube, which was to have been supplied in one piece, as a mandrell to jig the tail boom formers accurately. However, it is supplied pre cut to size so cannot be used so I used a tube I have spare from installing a bathroom shower unit, the rail the shower head can slide up and down. I added masking tape to the tube till it was the required thicness and then using a 3/4 inch ply sheet added blocks to support the formers at the required spacing and made up the boom support framework.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/venom_2_030.jpg)

Finally, a trial fit into one of the tail booms

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/venom_2_031.jpg)

The formers and longerons are not all a snug fit inside the booms so soft 1/16th balsa is added to the formers edges and the outside of the longerons and carefully sanded down till the fit is correct, a little time consuming but it reduces the amount of glue required to seal the gaps.

The next step is to mark the positions of the formers and longerons on the outside of the booms with a felt tip pen and then using a long dowel with a felt wheel on the end apply Hysol to the inside of the booms where the marks are and sliding in the frame, once dry it is a very rigid structure. I also added 1/8th ply sheet as doublers to the first two formers to reinforce the holes the tail boom tubes slide in as repeated removal and use will open up the lite ply former holes, this has to be done before the frame is glued in as has the holes cut for the elevator push rods and the rudder servo cable, this is run down a series of drinking straws glued together. Two pushrods operate the elevator and each rudder has its own mini servo mounted below each rudder, Hitec 5125MG's.

Post by: IB on October 03, 2006, 00:39:55 AM
A bit more done on the Venom over the last couple of days. The inner boom structure has been glued into place on both booms, I added a plastic tube to the inside of each boom to run the servo extension cables down for the rudder servos. Before the tailplane is glued to the booms I am going to rub them down so they are almost ready for painting, last time I left this task till after the tail was attached and I had to take care when rubbing down as the assembly is subject to damage when not attached to the fuselage.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20032.jpg)

The tailplane and elevator has been made up, the cutouts in the tailplane are to give access to the elevator and rudder linkages when the assembly is glued together, the cutouts are inside the boom "bullets". These cutouts are not shown on the plans but I did these on the last Venom and it gave a lot more room to work inside the booms.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20033.jpg)

Cut outs were then made in the booms to slide the tailplane in and the structure was checked for correct alignment and incidence angles.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20034.jpg)

Whilst waiting for the glue to dry when assembling the tailplane and elevator I made up the mounting rails for the engine from aluminium bracket, this is obtainable from B&Q or similar, in different sizes, its useful stuff to have around. I also added the hatch ply support strips, there will be further support strips fore and aft added later.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20035.jpg)

The next job will be to attach the boom spars to the fuselage, these are supplied with the wrong angle cut so they have to be recut to the correct angle. I found on my first Venom the tubes were cut to 17 degrees where they should be cut to 13 degrees, (this would have caused the model to perform a spectacular loop on take off and likely disappear up its own orifice), however, the model need a litlle down trim to fly level so this time round I'm cutting them to 12 degrees, this slight change in incidence will, I hope, do away with the requirement for the down trim.

Hi Ian

where did you get the noseleg oleo from, I have got micks oleo which looks a little flimsy

Steve
Title: Re: DH Venom
Post by: IB on October 11, 2006, 21:42:02 PM
The noseleg I have for the Venom is one MR supplies though it is made by Eurokit and their catalogue can be downloaded from their web site....................www.eurokitlucca.it

These are also obtainable from Motors and Rotors who stock their range, I certainly don't find mine flimsy though its been drilled  through for a 6mm pin type fixing and a brass insert added to give a little meat for the Allen grub screw to bite. With a little filing it can be made almost to exact scale. I've replaced the internal oleo spring with a much stiffer one so it won't bottom out as easy as I prefer any dampling action to come from the tyre itself.

 I've deviated from my normal covering method of tissue/dope/sanding sealer and I'm trying glass cloth and epoxy resin for the first time, so while I was covering the tailplane and waiting for it to dry between coats and rub downs I got on with a tricky part of the construction.............the engine access hatch, luckily I had the experience of finding out the tricks on the first build.

I use three ply tabs glued to the front of the hatch which key into three ply boxes glued into the fuselage, these are secured after glueing with glass cloth and resin.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20036.jpg)

These are the ply boxes in the fuselage, once done then the hatch is carefully sanded fore and aft only at this stage till it fits, then two ply seats are added to the inside of the fuselage to support the rear of the hatch.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20037.jpg)

Once this is done then the hatch can be carefully trimmed at the sides to fit, the hatch here sits on 1/16th ply rails that have been wetted or steamed into a curve to follow the wing section at this point, if flat ply seats are glued to the inside of the fuselage they will pull down the glass fuselage into a flatter section here that will prevent the hatch from fitting flush with the fuselage. After these were tacked in with thick Cyano I then reinforced the ply and fuselage with carbon fibre cloth and resin. This ensures the curve here is permanent and once done the final fitting of the hatch is done.

The front former for the hatch is added but only tack glued at the ends and middle initially, its not quite the right shape to match the fuselage at this stage, the hatch is trial fitted and I found that if a vertical cut in the middle of the former is now made the hatch now fits and follows the fuselage curve perfectly, whilst the hatch is in postion a scrap of 1/16th ply is glued the the centre of the former bridging the gap that has opened up, this is done by inserting ones arm up the jet orifice a la James Herriot fashion !! but without the sh*t on the arm after extraction.

The rear former is done the same way with the cut made in the formers centre and once done the fit is perfect but the hatch at this stage is a litlle flimsy so the addition of carbon fibre either side of the formers makes a rigid hatch that also fits as well

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20038.jpg)

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20039.jpg)

And finally the hatch in place, the method of securing to the fuselage is by a minature "Dzeus" fastener but this will be done at a later stage in the contruction.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20040.jpg)

Title: Re: DH Venom
Post by: IB on November 23, 2006, 22:50:13 PM
Right, been diving, got wet, and the Red Sea isn't red its blue so I want my money back.

Done some more to the Venom, cut the tail boom tubes to the correct angle as they are supplied with the wrong angle at 17 degrees when they should be 11 - 12 degrees, and I found out where the error has crept in so next time I see Mick R I can pass on the info as he steadfastly refuses to admit there is an error. On the plan side view are two wing sections for the root, the one where the boom is mounted and the other is where the wing blends into the fuselage pod, the latter is 17 degrees to the datum and in error the tubes have been cut to this profile whereas they should have been cut to the other wing section shown where the angle measures 12 degrees. This photos show the tube before cutting and it can be seen it does stick up more than it should

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20041.jpg)

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20042.jpg)

Here are the tubes now in place with the booms attached,  a fair amount of setting up the airframe is required to get this right as the booms need to be parallel to the vertical datum hence the string along the top of the fuselage whilst the wing datum needs to be parallel to the work surface so the tail angle can be set up to be also parallel to the wing datum (work surface).
Once this is all set up the tubes are bolted through the wing, I used load spreading plates on the wing undersurface in the form of ali sheet 20mm by 70mm to stop the nut and washer biting into the sheet. Incidently, there is a solid piece of birch inside the wing at this point to stop the section collapsing when the nuts are tightened.
The tubes are glued to the upper surface as well as being held in place with the nuts and bolts and I will cover the tubes at the mounting points with glass fibre cloth and resin bonding them to the wing surface, this will prevent any sideways movement of the boom tubes under load conditions.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20043.jpg)

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20044.jpg)

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20045.jpg)

Once the glue has set and the glass and resin applied, the tailplane rigging is given a final check.  Then, a few spots of Fiberpoxy to secure the tailplane into the booms whilst the horizontal alignment is monitored and after this has set the booms can be removed from the tubes and the tailplane can be fully glued up.
The major part of the construction is now complete leaving only the flaps and rudders to contruct then onto the finishing stages.

Post by: p51p47 on November 24, 2006, 12:40:44 PM
I was thinking the same thing...................

Am I right in seeing a 'butt' joint of the 12 degree tube, onto the top skin of the wing, with a ply infill to take 2 bolts ?.

I appreciate there is some sort of 'fairing' to cover over the tube ends which will add a little more stiffness, but there is a MASSIVE amount of leverage on those long booms, being spread into a VERY small surface area on the TE of the wing..............

.............or are we missing something?

Dear IB
It does not look much is holding those booms.
That could have been your problem with the last one.
They would last for a few flights and then start to fail
giving the impression you were going in and out of failsafe.
Please don't take offence, it is just a thought.
I would hate to hear this one has gone down.

I have heard of MR Lightnings doing similar things.
When the wing tubes that slide into the fus have not been housed strong enough.
Thus the wing angle of attack was continually changing.
Making it look like a roller coaster rather than a Lightning.

Hi All

I knew this "boom" mounting was going to raise a few eyebrows but all is not as it seems.

The plans, I must admit, if followed, don't give a fully rigid and strong mounting for the tubes as there is nothing between the upper and lower wing sheeting to prevent compression and flexing of the tubes once the booms have been fitted and I have my doubts as to the strength here under flight loads so I modified the mounting method on my first Venom and after the crash the wings were in one piece relatively undamaged until the fire destroyed one outer panel. The tubes and booms were fully intact and secured in place, this was the one area that did'nt fail on impact so I'm fully confident of the revised method out mounting the tubes.

What I have done is to fill the the space between the wing sheeting where the tube is mounted with a two inch wide, shaped to the aerofoil, piece of birch, this extends forward as far as the u/c plate and is keyed into the rear spar as well as the u/c plate. It is also bonded with Hysol to the root rib which is 1/8th marine grade plywood. The wing panel is glued to the fuselage pod and five inch wide glass cloth is applied top and bottom at the wing joint with two coats of resin. There are three load paths involved here as you can see so I'm confident the epoxy glass booms will fail before the mounting does.

This picture is of the wing from my first Venom showing the birch block before sheeting, on the new one, as mentioned, the block extends even further forward and it a little wider.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom_2-_024.jpg)

Phil,
The fairing cover which fits over the tube top and bottom is purely cosmetic.

On an aside, the Grumania Sea Venom really has a problem with strength, the booms on that model are of composite with no formers inside to stiffen the booms and the booms have the aerofoil cut out in them and are slid along the wing till they are in position and just glued. One tail strike on the port boom on take off on the one I've seen caused the boom to become loose which led to the plane only able to turn right and led to its demise.

Ian.

Ok....thanks for the explanation................if you have hardpoints for the boom mounts extending well forwards, passing through the rear spar webs and attaching the the main gear plates, I agree that that should spread the loads far enough so any problem disappears..................

I CANNOT believe that this kits is still being sold without your (or a similar) modification being shown on he plan as standard. Have you approached Mick about this? as surely other builders have come across the same issues, and I'm sure those without a 'structural' mind will have blindly followed the instructions, and had a BADLY compromised rear end structure because of it...............

Because the main u/c retract cylinders are inside the fuselage pod where I intend to fit two saddle tanks I needed to make up two custom fuel tanks to fit into this space. I also needed them to be as big as possible and around a litre capacity each.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20049.JPG)

Here's the space and the problem.

Out came the Jelutong and a quick drawing, some calculations and a plug was made.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20046.JPG)

Then I made up the moulds.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20047.JPG)

And the fuel tank glued together and sealed.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20048.JPG)

And now fitted into position.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20050.JPG)

I did a capacity test along with a preliminary leak test, it holds 1.2 litres (bonus) and did'nt leak. When the fittings are installed I will do a proper pressure test.
The Venom will have a total fuel capacity of 3 litres plus whats in the air trap, should give a comfortable 8-10 min flight.

While I was making up the tanks I covered the wings in 1oz glass cloth and two coats of epoxy finishing resin. After doing the necessary with wet and dry it was now time to add the wing tip tanks.

First time round these were an absolute pain in the a*se to do, getting the two halves to fit together was like shoving spaghetti up a wild cats ar*e. The problem was in the way they had been moulded by the manufacturer, the original intention was to have one half semi circular with no stepped edge and the other half with a recessed step so it would fit inside the other half. Well, the best laid plans of mice and men etc. The half with the step has it recessed so it lies inside over one edge and sitting proud over the other edge, these were never going to fit though I managed with plenty of cyano and force.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20051.jpg)

This time round the mouldings are still the same so I decided to do away with the moulded in step and cut them plain and glue in my own step using 20 Thou strips of Plasticard. Here's what is provided, two round reinforcing formers ( that don't fit ).

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20052.jpg)

I used tape to mark a straight line on both halves for the cut.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20053.jpg)

Adding the two formers and a stiffening strip to one half. The formers have to be sanded down to get the other half of the tank to fit correctly and I finished up sanding so much off the forward former that I had to add another former as a doubler to this former. Once satisfied with the fit I then mounted it onto the wing tip ensuring it was lined up with the centrlines etc. Balsa packing and lightweight filler was used to get a curved saddle and then it was finally screwed into place.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20054.jpg)

Once in place the other half with the plasticard strips was glued into place and all that is left to do is to apply some filler to hide the seam.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20055.jpg)

Does'nt look right though with see through tanks  :-\


IB
Title: Re: DH Venom
Post by: IB on January 23, 2007, 22:23:42 PM
The wing tanks seams were filled and sanded to the correct shape and the forward extension added then some litho plate and more filler added so the smooth blend in from wing to tank was achieved.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20056.jpg)

Then the cut outs were made in the fuselage for the inner flaps were done with the edges lined in 1/32 ply as a seat for the flap, there is already a servo in the wing to drive the outer flap and a servo will be added inside the fuselage for the inner flap. I've purchased one of these newish WEATRONICS RECIEVERS which are a dual reciever, Powerbox voltage regulator and Matchbox all in one unit, this has the facility to drive up to eight servos from one channel though I will be using the flap channel to drive the four flap servos, mismatches in the linkage throw will be programmed out using the Weatronic Matchbox feature, I've been playing with this and this reciever is absolutley knockout.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20057.jpg)

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20058.jpg)

Also done are the rudders and the elevator and aileron trim tabs.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20059.jpg)


The movable parts of the wings and tailplane will be tissue covered as I can't be doing with the glass/epoxy covering on such small difficult to handle items but I must admit I do like the glass/epoxy method. I've never tried this before and the finish is as good if not better than tissue/dope/sanding sealer. The wings and tail surfaces will be covered in paper cut to represent the metal panels as I find this gives a very real scale effect. The flush rivets are applied with a sharpened brass tuce which cuts into the paper but not the tissue or glass cloth underneath.

Popped up to the Cosford Museum last Sunday to look and photo the Venom FB4 there, I have a set of close ups of a Venom FB50, the export version of the FB1 but needed the FB4 version. Great museum, last time I was at Cosford was back in 71 &72 as an RAF apprentice for the inter apprentice schools swimming and cricket matches, dos'nt change much !!!

Spent the last few sessions making up the flaps and airbrakes and also making the wing cut outs for the wheels and undercarriage doors.

Here are the two starboard flaps finished and hinged, the airbrake outboard of the flap has been removed, I had these airbrakes working on my first Venom but because of the wekness in the hinging system I never tried them in flight but they looked good taxying in deployed after a flight. This time round they are fixed, but need to be removable as the outer wing panel will not slide into place unless they are deployed or removed due to the angle of the wing tubes.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20060.jpg)

This is a view of the port wing with the flaps retracted and the air brake fitted. Also, the undercarriage doors are in place but as these are clear acetate they are'nt easily seen, great for lining up with the leg to drill out the holes for the mounting clamps though.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20061.jpg)

A couple more photos showing the outer and inner flap servos, the outer flap servo is in the wheel well whilst the inner flap servo is in the fuselage between the wing root and saddle tank.

A quick update on progress so far, the flaps were fitted and set up using the Weatronic programme on the laptop I have whilst plugged into the reciever so I could make the fine adjustments in situ. All four flaps now move equally throughout the travel range, each individual servo has its own "curve" which on the graph displayed by the PC looks the same, they must differ slightly though due to linkage and servo differences.

I have spent some time preparing the fuselage for painting, the fuz was manufactured without a gel coat as its epoxy not polyester so there were quite a few pin holes to fill, roughly about a weeks worth of filling, sanding, coat of primer to show if they'd been filled followed by the same process till I was satisfied. Then the panel line detail was scribed onto the fuselage and the panel lines marked onto the wing in preparation for the paper panels being applied.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20064.JPG)

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20065.JPG)

Here is the underside before the paper panels are applied.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20066.JPG)

The first two panels glued on. A slight gap of approx 1/2mm is left between the panels to give "depth" to the lines, this is easy to do as the gap can be accurately done by gauging how much of the black marking line is visible, it disappears if the paper panels are pushed together.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20067.JPG)

And the underside finished on one side.

When the wings are completed they are given two coats of thinned sanding sealer and lightly rubbed down, then the rivets can be added with a sharpened brass tube which will cut through the paper but not the glass skin underneath.

I'm waiting on a delivery of rib tapes from Mick Reeves for the fuselage so I'll see how these pan out when applied.

Having got the airframe covered it was time to fit the boom fairings to the wing/fuselage, however, the top fairings are too short and are a b****r to fit even if they were the correct length, the underside ones are fine. See this photo.

Short by nearly two inches.

So I made up a mould to make my own in glass fibre, this is the start.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20069.JPG)

The initial base, the rest is filled in with balsa, shaped and then given a coat of epoxy resin and sanded smooth, then a mould cast off this.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20070.JPG)

And finally the finished boom fairing, this has not been trimmed to a final fit yet, that is the next task, then its onto detailing and painting.

Hi Steve

One of the errors in the design of the model, I have scale drawings and photos to base the changes on, that said its the only major error in the overall profile, the rest of the airframe is pretty accurate. I get the impression that the boom fairings were made after the prototype was built and were'nt taken from his model, just made "separate", nt the way to do things !

Doing the same as my first one, the last Venom on operational RAF service, 28 Sqn, Kai Tak, Hong Kong 1960, WR539.
I have lots of documentation on this particular aircraft, the actual plane is in bits awaiting restoration at Salisbury Hall, I've offered to do it for them over the Easter weeknd as I've not much else on but I've not heard back from them

 :) :) :)

Theres a piccy of my first one in the scheme at the beginning of this thread.

Thanks lozza.

Got the upper boom fairings in place, using glass fibre mouldings make for a much easier fit and knowing I took the side profile from my scale drawings and photos of the full size I know these are accurate to scale this time around, if not then I've only myself to rant at.

I've decided not to use the lower boom fairings as supplied so I've also made a mould to produce these as well, these will fit as accurately as the upper ones so whereas I've not been looking forward to constructing this part of the Venom its taken a niggle from my mind thats been concerning me since I started the build.

Heres the upper booms nailed on.

Hi Ian,
Been a long time!My Venom has about 25 flights on it since new and it has been a real joy.I replaced the M.R. retracts with air driven retracts and the nose strut has been replaced with one from Micheal Binder after snapping two of the Eurokit struts but other than that has been trouble free.I agree with changing the stab to 12 degrees,mine reqiured alot of nose up trim as well.I thought it might be the C.G. but I think now it is the stab incidence.Your new Venom looks fantastic.I love the new pod fairings and fuel tanks.My fuel system uses two of Grumania 1.6 litre tanks and an Intairco header tank and has been problem free.My PST 600 is the perfect engine for this aircraft and runs like a jewel.Keep up the good work and I can't wait to see the flight piccies,Cheers,John Vasil

Hi John

Good to hear from you, where are you these days ? Far East or the Wild West ? (in relation to the UK).

I 'll have a look at the strut you mentioned, one never knows, I may have similar issues knowing my landings !

I'm just about at the painting stage, just one or two things left to do and also work out the canopy fixing as I have to have it removable to get to the innards of the beast. I've one or two ideas which I will share when I post the next build details. In the meantime I think I'll wag off work this Saturday and play with jets as we have a promising weather forecast over the holiday weekend  ::cc

Hi Ian,
Just replyed to your post,tried to add a photo and the whole thing disappeared into cyberspace.That was with Mac so I'll try Windows.I'm still here in Hong Kong(five more years).I do all my jet flying in Bangkok with the very nice guys from PST.I'm using the nose strut from Behotec#230120 and I'm hoping this will iron out some of the bumps.The first two struts broke in the same place,right where the holes are drilled for the steering so I think a machined strut with oil damping will help.My jet is looking a little beat up so I think this winter I will give it a bit of an overhaul with new paint,fix all the dings and add some scale details such as a cockpit.I'll take some picture next I'm In Bangkok.I'll try to post a picture of My Panther which has been a real joy as well.I,m currently working on Comparf Mig-15 which should be ready for the fall I hope.Next week I'm off to Toronto for some leave and a visit with the folks.I'm also going to Top Gun in Florida for a few days to help out with the Pst Team.Talk to you soon,Cheers,John

To operate the twin rudders I'm repeating the method I used before and driving each rudder with its own servo and breaking all the rules by putting these in the bullet fairings at the rear of the tail booms. There is no other practical way of doing this and retaining positive slop free operation so I've used Hitec digital 5245MG servos being fairly lightweight and small enough to fit inside the bullet. I'm looking at church roofs with an evil eye !

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20076.JPG)

And with the rear cover added no fouling of the push rod was tested, all OK.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20077.JPG)

Litho sheet strips have been added around the tail surfaces to replicate the full size and a little light weight filler used to feather these into the tail booms.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20079.JPG)

I'm looking at one or two methods for attaching the canopy, it has to be removable to gain access to the internals so this will occupy the next part of the build, ignore any bad language heard from this locality.

The canopy was first masked off so I could size and mark it to fit.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20080.JPG)

When satisfied after the hacking.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20081.JPG)

I then glued shaped beech strips inside the fuselage and drilled and tapped holes and screwed in four 2.5mm bolts to act as guides for the canopy fixing.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20082.JPG)

Then made up the frame with slots in to engage the four bolts.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20083.JPG)

And finally after adjustments ( I built in vertical and horizontal slots to adjust for an accurate fit ) the canopy now drops onto the four bolts and then is pushed back locking it tight into place, no further fixing is required as the airflow will just try to push it back further thus holding it in place ( probably fall off when inverted knowing my luck _

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20084.JPG)

Now the outer framing will be done and the bolts will be hidden after cutting back by the framing. The reason for the removable canopy is so I can install the gubbings necessary and the seat and pilot and have relatively easy access to service the internals.

Been fettling with detailing the canopy by adding the frames in litho plate and also adding the "rib" tapes.

On the full size Venom, the fuselage forward of the engine access hatch is made from wood in the same way as the Mosquito was constructed, very De Havilland ! The main spar carry through and engine mounts were mounted to the rear bulkhead of the wooden structure, everything else was metal.

As a result, the whole forward fuselage was covered in linen and doped and the seams where the ply sheets butt jointed together were reinforced with linen strips pinked in the same traditional method as wing rib tapes.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20085.JPG)

All the edges of the cut outs in the fuselage for hatches and catches etc were treated in this way. When you get up close to the aircraft it looks quite rough and not the smooth surface depicted in photographs. I added the tapes and then coated them with a couple of layers of sanding sealer, then blew over a test area with primer to see the effect. It was as I wanted, not too obvious yet revealing the pinked edges at 25 to the inch ( 1/6th scale ).

Adding the litho plate frames is a fairly long job as the glue I use ( R/C Modellers Glue ) takes 12 - 24 hours to go off, I like this stuff as its water soluble so any excess can be removed with a little meths even after its set.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20086.JPG)

The forward part of the canopy almost done.

Hi Ian,

Looking fwd to seeing your Venom on Sunday at AB...I'll have my part finished DH-108 there which is racing towards the finish line (been at it for 8 years, reckon it'll be ready for flight in 1, maybe 10 years or so!). You're right abt the Venom (Vampire) fuselages being less than smooth. I took a whole load of pics of a Vampire at Kemble last year and you could clearly see the 'rib tapes' on the fwd fuse, along with many cracks in the plywood veneer! Still a beautiful aeroplane though! See you Sunday,

Dick

Mark Leavesley does an excellent Ejector Seat kit and a half pilot that does not take long to put together, its somewhere on his site

Hi Ian, Iíve been following this thread from the start; you appear to have turned out a very workmanlike effort, well done.

Back in 1997 I embarked on a huge project, to design, build and fly a 1/6th scale DeHavilland 110. I could expound on the subject if you wish or perhaps even start a new thread.

The reason for this reply though is just to say how good the two aircraft might look flying together one day, as they are the same scale. Does anyone have a 1/6th scale Meteor? Does anyone have a 1/6th scale Javelin?

Last photos before the painting begins.

All the access panels and fuel filler caps have been added as have the navigation lights and pitot head. Markings for the rivets are on the tail and have been done on the wings since the pictures were taken, the full size Venom had all the rivet heads filled and sanded flush where the aerodynamics were deemed important as the prototypes exhibited a severe tip stall and it was thought airflow breakaway was the cause. This was eventually cured by adding fixed leading edge slats at the wingtips plus a wing fence at wing midpoint, but the production Venoms still had the rivets filled. Operational use popped the filler off in some areas so I will be using evidence from one of the Swiss Air Force Venoms where these areas are. Incidently, the rear quarter of the wing and tail were'nt filled and looked quite rough.

Started spraying the model on Saturday (at last) but had to go and rest at Kemble yesterday where I had the icing on the Fathers Day Cake, a superb display by a full size Venom..........the mutts nuts...... ::cc........even though it was an FB1 (mine is an FB4, there are one or two differences), you should have seen my sons face when the pilot initiated the engine start up, they use a cartridge start which emits a huge plume of smoke from the engine cover vent and a noise like car tire going down very quickly, I suppose I was cruel not warning him..............heh heh heh.

Anyway, a couple of pics of the story so far.

John, how are you doing ? Appreciate the comments very much.

The C.G. is 1/2 inch back from the front of the engine hatch leading edge ( if that makes sense ). It can be moved back further by about another 1/2 inch, as mine finished up when I removed a little nose weight as it was quite damped in pitch, I never got the chance to move it any further back. Its where I'll start when I cget around to test flying, at the moment it is being masked off for the final colour coat ( green ). I'll post some piccys up in a few days.

Now the main part of the painting has been completed, with the exception of the serial numbers which is in hand, I've been fitting the undercarriage doors. I'm leaving the front nose leg door till last as this is the most awkward one to do. This is the one that swings back and forth as the noseleg cycles. The only way to do this is to replicate the full size mechanisms, I did this on the first one and it worked perfectly but its a little fiddly setting up the swinging links, more of this when I do it, meanwhile, some piccys of the doors and we're not talking "Baby, Light my Fire"  :co

Finally finished the painting with the serial numbers for the booms and the underside of the wings added. I must thank lozza for the excellent paint masks he provided, they were the mutts nuts. I've never used these before and they certainly save time from my usual method of masking off.

(http://www.rcmf.co.uk/RCMFLive/albums/userpics/11858/Venom%20103.jpg)

Whilst waiting for the paint to harden off before dirtying down the airframe, I've started the radio and turbine installation. I need to keep room inside the cockpit for an ejection seat and pilot. There is not much room to play about with especially with a reciever the size of the Weatronic so everything is attached to the cockpit sides. On the floor of the cockpit is sited the last  fuel tank ( 1 litre ) and the hopper or air trap, the seat will velcro on the top of the tank with Flt Lt Hartley in it, I can easily remove these to get at the gear if need be.

Dear Ian
Congratulations are in order for your beautiful Venom, any chance you could bring it to our Battle of Britain event at Coltishall, on Friday the 14th of September. It would be nice to see you again, and as you are probably aware that Venom's were at Coltishall between 1953-56.

Dear Ian
A damn shame that, if anything changes please let me know.
A Lightning and Venom in the Coltishall skies would have been wonderful.
Just to reiterate once again, the Venom is an absolute credit to you.

If I could ask your advice please, I am trying to find a tool/way to replicate the pinked pieces on the elevators and rudder on my 1/4 scale Spitfire. They need to be twenty points per inch.
I can buy them of MR but I would rather try and make them myself.

A quick update, once the serial numbers were applied, I started to dirty the model down using my usual wash method then after a break for a holiday and the Nationals I made up all the lettering for the airframe, once these were applied I fuel proofed the airframe and finished off the radio and engine installations. This went smoothly until it was all done, then I pressurised the air systems only to find a leak and managed to blow off the end cap off a door cylinder.

Oh well, the leak would be in an inaccessible place, sods law, gear out and a y-connector found to be the culprit. I would'nt mind but having experienced this before I test each individual component before fitting, this one obviously stuck two fingers up at me  :nananana:

Door ram replaced, gear back in and all is well, system pressure at 100 psi held for a 24 hour test, I'm happy !

Spent this afternoon programming the Weatronic reciever with my laptop and getting the servo senses the right way round and the throws to where I want them.

Whilst the uneducated eye might jump to the comclusion that this was caused by a model jet, the experienced incident investigator will be able to confirm there is no doubt whatsoever that the damage shows the obvious signature characteristics of a cat which has been booted at speed by a selfless and hardworking husband who had spotted it just as it was about to cr*p on the patio.

Well the basic certified copy runs to one Wren Supersport. The "Silver Service" provides a certified copy plus a telephone support line offering authoritative-sounding confirmations after announciing itself a "Home Office - Lawn Cat Incursion Investigations Department". The full "Gold Service" provides a team of forensic investigators in SoCO Suits to quarantine the affected area, take samples into a mobile lab and then announce a Moggie Movement Order authorising teams of marksmen to shoot all cats seen within 1000m of the property.

Prices for Silver and Gold depend on the location and nature of the particular incursion, so they are subject to specific quotation. Of course for the less profligate customer there's the "Popular Plus" service, which comprises a man with 2 square metres of turf and some gardening equipment in his van. This costs about £250+VAT.

Today I test flew the Venom  :af

I actually finished it ready to fly mid September but I went off on holiday for a month and since returning, today was the first day where I wasn't working and had half decent weather !

A very grey day at my club strip  at Wroughton, but flyable ,with the wind straight down the runway, the model was assembled and two range checks were done, one without the engine running to establish performance of the Weatronic Receiver and then one with the engine running to see if I got the same range and no glitches.

A refuel then with Geoff White as my lookout/spotter and Dick Spreadbury lurking with a camera I taxied out and opened up.
Certainly the most relaxing test flight of any model I have built, it flew straight off the board needing one click of up trim which I took off on the second flight. I had 30% expo on the ailerons and whilst it was very stable around the neutral point the aileron roll was a tad quicker than scale so I shall increase expo to 50% and also reduce the throw. A few circuits, rolls and a couple of loops and then at 5 mins the timer reminded me it was time to set up for a landing. A gear pass was done then downwind I progressively lowered the flaps to 75%, no pitch up or down, great, so turning onto short finals I increased to 100% and let her just settle onto a very credible three point and no bounce landing.  ::cc

Chuffed or what ! So a little later I had a second flight, this time a little longer having though forgot to increase the timer, so a manual count after 5 mins and I think I managed 8 mins or thereabouts. Another smooth flight this time exploring aerobatics. Rolls, loops, reversals, Derry Turns and some low passes.

The light had gone and the rain was starting so I packed up and will have some more flights when the weather is better, but in the meantime here is two shots taken by Dick in very trying poor light condidtions.

I think the miserable looking day compliments it perfectly. It's a fantastic looking model and the painting and weathering is, in my opinion, pretty much perfect (which isn't something I'd say about many models - especially my own  :''). Against a typical crappy British day as a backdrop I think you have made a hugely convincing model of a DH Venom  :uk: :uk:

Had that hangar been further in the distance to make the model look bigger I could easily have believed that was a real Venom  :D

Well done Ian!!
You have now built two Venoms in the time it's taken me to order the wheels from MR and loads of balsa for building + skinning mine!!
P.s Question,
 For the new reprofiled wing root rib did you use the same flap cutout dimensions as Mick did on his root rib?
The tip rib is that the one from the kit minus 3/32" top and bottom?

cheers
Best of luck and many happy landings
David
Title: Re: DH Venom
Post by: IB on November 25, 2007, 10:53:26 AM
Hi Dave

The tip rib I mention is the ones supplied in the MR semi kit and is standard ply, not lite ply. Make one more and remove 3/32 inch off this top and bottom and you have the tip rib template. Using the root section off the fuselage, do the same.

The flaps as shown on the plans are correct, almost, but refer to scale drawings and you need a servo for each flap (4 ) and don't use the method as shown on the plan to operate the flaps or you will  experience blowback and twist as the aluminium flap joiner has to distort slightly as the flaps are lowered, use litho sheet that has not been annealed so it is still springy and reverts back to its original bend as the flaps are raised. You'll note the difference in hinge line between the inner and outer flap ! On the full size the hinges are aligned vertically and offset to make the hinge line parallel. A little complex to achieve on a model and not necessary to achieve the scale flaps.

PM me if you've any questions and get cracking !

I hope I have done the right thing, and Ian, I hope you are a very patient man, as I sure there will be loads of questions that you will be able to answer.
Building experience so far on jets, Avonds F15, Avonds F16 and Boomerang XL, so the Venom is going to be one hell of a challenge ( but hopefully worth it ).
Fantastic Venom you have built there Ian ( if mine turns out half as good, I will be one happy man )

Hi Simon,

The Venom is not difficult to build at all, at least not now I've sorted out the issues that existed though its not a "quick" build by any means but it is a superb model once completed and it has no vices in the air.

I managed another two flights last friday at Abingdon at the Winter Jet Meet, it was effing cold and very gloomy, on the first flight I disappeared into cloud/mist on the first circuit so I had to keep it close. Pete Tindal took some photos which he very kindley let me have, I reworked the airbourne shots into a semi presentable state. One day it will be nice and sunny, says so in the Scriptures so it must be true !

Title: Re: DH Venom
Post by: IB on December 17, 2007, 08:56:08 AM
Hi Ray

What a coincidence, I met a gentleman last Friday at Abingdon who flew the FB1 and FB4, I spent some time chatting with him about the Venom and its flight characteristics, seems mine is very much like the full size inasmuch as it will pitch up if the flaps are lowered when the airspeed is high. I did'nt experience this on the first two flights as the airspeed must have been correct but on its third flight because I was flying it very close in due to the poor visibility it pitched up as the airspeed was high when the flaps were lowered, not a problem though as a power reduction and a gentle push on the stick stopped any further pitch up.

Must get on with the Hunter, just waiting for the retracts to be made and then we'll be off !  :af

The full size Hunter does the opposite to the Venom then when the flaps are lowered at high speed.  Especially to 'inadvertant' flap selection, in fact the RAF lost several Hunters to this problem before it happened to a T-bird and the IP realised what had happened.

Anyway Ian, get that Hunter started :af  what mark are you doing?


Mark.
Title: Re: DH Venom
Post by: IB on January 11, 2008, 21:48:01 PM
Hello Brian,

I'll dig out some photos of the nosedoor attachment system, however, its done as per the full size which is shown on the plan. The top part of the door has two metal strips which are allowed to swivel and these in turn are attached to the u/c mounting plate and these too are allowed to swivel at the fixing point.. So far so good, the bottom of the door has two rods attached which pivot in the vertical plane, these in turn are fixed to the nose leg on a sleeve around the nose strut. These rods attach to the sleeve via a ball and socket fitting which allows the rods to swivel. As the leg retracts backwards the rods pull the door back and the two metal strips allow the door to swing down and backwards and fit securely to the fuselage when the leg is fully retracted. The length of the strips and rods are fairly critical but fine adjustments are made in the rod length as these are threaded 2mm push rods. The reason for the use of a sleeve over the strut is so the door stays in position as the strut rotates for steering purposes otherwise unwanted strain occurs on the door fixing points and also the sleeve can slide up and down the strut which ensures a good closure fit.
Clear as mud but all will be revealed in the photos.

Mark,

Hunter Mk5, straight leading edge, no extension............the classic Hunter..............Suez colours and piloted by Flt Lt J. R. Hartley !

Hi Ian , thanks for reply can I ask what your finished weight of your venom and as to the pro linkx retracts do you know the type your mate is installing as two possibles, one showing up to 8kg and the others at up to 20kg, have you got any photos of your revised linkage of your front doors as you state you have fitted balljoints

Title: Re: DH Venom
Post by: IB on June 25, 2010, 16:07:02 PM
The Venom finished up at 22-23lb dry though I removed some noseweight which I thought was around eight ounces.

Not sure which of the two sizes he's fitting but I would go for the larger size to err on the side of caution.

No photos to hand but the ball joints are attached to the strut ( drilled and tapped ) and the other end fitted onto the door into an elongated slot to allow for the noseleg steering and retained with small collets.

I realise that this is an old thread and you are probably sick of requests for tanks etc. I have just bought a Mick Reeves Venom here in Australia. It is of unknown vintage so I will treat it as one of the early ones. My questions are;

Do you still have the rib profiles somewhere? There is a local kit cutter from whom I can get new ribs cut.

Are your custom tanks still available? They look like the easiest and best way to go.

Is your Venom still flying?

Thanks for your time Ian

Col
