Hi Steve,

Dead easy question even for me!  Take a piece of triangular trailing edge balsa and soak it.  Then use your knife to cut a lot of slots on the strip and glue and pin in place.  That way it needs next to no sanding.   :af

I laminated some soft balsa together, marked out the plan view and section then cut to shape. Lots of sanding later got a profile I was happy with. Then sanded out the base to match the fuselage curve and finally cut out the turret clearance hole.

Optional: Add expletives of your choice between steps 2 & 3 when you realise you've taken too much off  ...

Doh ! That was of course for the mid upper turret .....  :-[
I haven't actually fitted the rear turret fairing at all  ......

Hi Steve
         I done it different again ::)
I Held a piece of 1/16 balsa against the back end, cut in a 'u' to fit tight down the lower sides, then whilst holding in position drew the shape of the fairing i wanted, cut it out and glued to the rear former. I then simply sheeted with 1/32 sheet with the grain along the fus. Think it took 2-3 pieces cos of the funny shape I.E. bulged sides and flat but raised top. Very little sanding and hollow.
Don't forget you will have to cut the elevators to clear.

Cheers Walts
p.s. Gordon, you lucky fellow Re. the workshop potential :co

Hi guys...just a winge to Wiz.  I can't understand why it's so difficult to post pics on here now.  In the 'additional options' the attachments have been disabled, so no way to do it there.  Uploaded a pic to the gallery then got lost in trying to get it into this post.  The help area is also of no help whatsoever.  All in all Wiz, not impressed with the latest format dear boy  :'(

Yup, it was a pic to do with Steve's question  :ww

Steve, go to the gallery and look at the latest additions part, you'll see what I mean about how I did it.  :af

Gordon, Is this what you wanted,  this is the first attempt at using the post pics from the gallery and it worked first time



Have a look here http://www.rcmf.co.uk/4um/index.php?topic=25736.0 to make sure you are doing it correctly :af

Gordon,

Many thanks for trying - couldn't find the pic!  I absolutely agree with you that the new format is not great - I tried to post a pic a few pages ago, you might remember, and failed.  Also, I was trying to show my friendly model shop owner the same pic in the gallery on his laptop and found that you have to log in  to look at them!  I couldn't remember my password, so that was that.  You can view the threads as a guest, so why not let non-members see the pics?  I'll take rcfanuk's instructions next time I try.

Anyway, I did it Walt's way, 'cos this was close to the idea I had in my head anyway, but thanks to Walts, yourself and BD for responding so quickly.  Yes, walts, I was about to start the elevators when I realised that they would need a cut-out for the fairing!

Cheers

Steve

Is that the same Gordon who hadn't flown his Lanc last time I visited this site back in the last century?
House and family are no excuse mate. Get out there and do the business. (but not like I did).

Dek?  I knew a Dek many moons ago when the paint on my lanc was still fresh and the hobby seemed so full (fool) of time to do   8)  Howya doing Dek?  Long time no hear.  Me?  I'm painting the house soffits just now in a gap when it's not raining or blowing a gale up here!  Been thinking about the new model building I hope to start next year....keeps me sane after putting on the third coat of paint!!! 

 Still couldn't get a pic onto here...clucking bell!!   >:(

STEVE,

Thanks - I thought I'd done that, but maybe it was finger trouble.  You have to scroll down to ensure that you've got the entire URL: maybe I missed some!

BTW, Am I right that you have to be a member to view the gallery?  I was trying to show my local model shop proprietor the pic and he couldn't access it without logging in.

Regards

Steve

Gordon,
        Tell me about it! I'm getting a skin full of house work and garden renovating at the mo :( Still it passes the time until the weather is perfect, nearly there now, would be a shame to risk it on a less than perfect day having waited this long. Same go's for the Jug and Camel, all waiting for maidens :)
Dek old chap its good to hear your still around :af
And Steve,............What can i say looking superb as usual :af any idea of the weight at the mo?

Walts
p.s. I don't even bother trying to use the up loader any more, I just use a hosting service my good lady installed for me ;)

Walts,
As you see it in the picture, it weighs just over 5lbs.  That is minus Rx, props, elevators, ailerons, underwing covering, paint and. of course, batteries.  I will probably go LiPo and, depending on where the c.g. comes out, may use a separate RX battery way up front if ballast is required.  I hope I may be on course for no more than 7 lbs.  I have since given the wing top surfaces the Halfords-Primer-and-rub-down treatment to fill in any slight imperfections in the glass, so that looks like the fins - horrible at first glance but a beautiful smooth surface redy for top coat.

Hi Steve
         My Lanc came out so bl***y heavy that I've now got a separate RX battery wedged tight behind the bomb aimers dome, and a 10 cell 3300mah nimh tight against that to get the balance right :o
I've decided not to mess around with anymore prop changes at the mo, going to try it as is when i get a perfect day. Its got plenty of power now, just don't know wether the motors can stay the abuse till i get a chance to throttle back. Its not ideal but thats the price i pay for building a ridiculously over weight model, and I'm not prepared to plough any more dosh into this, i want to move on :)

Hi all,

Steve, nice pic but why is it so small?  (the pic i mean  :ev).  Think everyone is a little peeved off about changing a good system for uploading pics (rcfanuk please note!).  Ok, so it saves space on the site...point taken and accepted, but why spoil a really good facility that your members use...upgrade your system dear boy?   :af

Walts....100% agree on the lanc front, I'll be running her this summer and if she's a non-starter then so be it.  I've got loads of fun from making and exhibiting her and would recommend the 'new' kit to anyone, so the flying is the jam on the bread and butter in my opinion!  :af  How's the 'house' work?  My soffits nearly painted and guttering now bought....gawd wot a price!!   :'(

Gordon if you click on the small pic it will open up a larger one  :af, this saves everyones bandwidth by not loading large pics, unless you want to look at them. This is especially good for our friends on dialup. :af

Hi Gordon
           The house work is going to be a never ending saga, having not long moved in. I think I'll have a good go at it until the summer gets here then lay off and get some serious flying done  :af
Have you got any plans to build anything else at the mo?

Hi Guy's
         Just a quickie to say i maiden-ed the P47 Jug this morning. Had a little scare when i hand launched it as it dived for the ground. But i kept my thumb on the elevator stick and managed to retrieve it! After putting in loads of up trim the rest of the flight was a breeze! It flies with authority even on the supplied 480 can motor and has a real presence in the air being capable of flying quite wide circuits with out being difficult to see. A stunning little model, Well done E-flite :af

Cheers Walts :)

Well done Walts!  Good to know some of us have broken the duck and got airborne  :af  It seems with these 'chuckers' that putting in a good measure of up elevator is good insurance?  As for building any more models...I doubt it for this next year since there's so much to do in and around the place.  :'(  I hope to focus on the Ripmax Spitfire I've got and if successful I'll fly the lanc in the summer, for good or bad  :ww

Incidentally, saw an unusual balsa kit for sale on e-bay...it was for a small Boulton Paul Defiant  :co

Walts.....here's something unusual, me talking about the lancaster!  Was in Borders today with SWMBO and daughter and did something unusual for me; I bought a model mag!  No, just never do, but this time it was the May edition of RC Model world, because it has a really good picture of a launch dolly on Page 80.  Now that got me thinking on 2 fronts. 

Firstly, if your lanc (and perhaps mine too) used a dolly, the weight saving could bring the model seriously down without getting into the tail chasing mode of larger motors/props etc etc?  Also using a dolly could help anyone who has a rough grass strip where retracts could be damaged (but landings could be fun???).

My more serious idea would be in fitting a dolly to my Ripmax Spitfire (and what about your Thud?).  I can use my local 'B' road at weekends as it's seriously quiet on Sunday mornings!! 

Incidentally, RC Model World has a smashing article on a Mk22 Spitfire and RCME has a rave review of your Thud Walts.  :af

Nahh Gordon, mines going out on its rather heavy battery load, could look quite realistic returning from it's first mission with smoke billowing out the nacelles, must get some pic's :ev

Hi Guys,

just thought I'd give you an update of my Lanc....

I had a major burst of effort this last two weeks and reached the stage where I got the plane assembled and running under its own power yesterday.  Did some taxies on the driveway an it looked and sounded great. Still have a few tweaks to make but it should be in an airworth condition soon. Now all I need is a runway... I'll get some pics soon.

I did a cofg check, having put the LiPos as far forward as possible I found I needed about 2.5 oz of lead to balance. I've still to re-measure its all up weight but based on earlier weigh-ins I'm anticipating ~5lb 12oz unpainted, so that combined with a measured static 440W should get me in the air.

In the mean time, I'm interested in the take of dolly you were mentioning Gordon, for my Hurricane and still to be built FW190.  Being in Hawaii I doubt I could get a copy of the article, could you provide more detail?

Thanks

Simon

Sounding good Simon,
                 and certainly bags of power to weight ratio there.Can't wait to see some pic's, That must make nearly 4 Lanc's on here waiting for maidens. I was lucky to get an envelope in the wind to fly my little P47 in last week. Just waiting for another and its the Lanc's turn' Win or lose!! :af

Take care Walts
p.s. Gordon, i always keep one in my flight box just in case. But pray i don't need it ;)

I wish I had found this thread back in October when I started my Lancaster. I have been posting progress as I went to the following thread at RCUniverse:

http://www.rcuniverse.com/forum/m_3322308/tm.htm

It's pretty much built to plans with some minor deviations with the cowls. I plan to run 6V 400s on gear boxes series/parallel. I am currently pulling ~350 watts at 4900 RPM with 9x7 Master Airscrew three blades. I think I need to change my gearing from 2.6 to 2.3 and cut down the props to ~8in to get the RPM a little higher. Anything above 5500 should be a bit better as far as pitch speed goes.

I choose the Master Airscrew since they make pushers in this size. I currently have them set up so they counter rotate. Here is a link to a run-up I did a month ago.

Small | Large


My primary concern with my setup is getting proper cooling around the motors. The cowls don't leave much room to add that.

Scott.

Hi Scott,
         and welcome to the RCMF Leccy Lanc thread :af
 I've just read through your entire build thread, and some mighty impressive work there.
As Phil G pointed out the weight is a big issue with this model, His post re scale weights was quite interesting, but believe me a 7 1/2lb model will not fly on the recommended power train, I've proven that and have subsequently had to modify my gear boxes to accept 8x6 props and added more cells to increase the power! I've got the power to fly now, but can't guarantee the set up will be capable of maintaining it :o
As soon as the wind drops I'll be giving my one its second attempt.
Keep us posted with your progress
All the best.
Walts

Hi guys

Weighed the Lanc last night, 5lb 14oz unpainted so slightly more than I expected but not by much. I figure the 2.5 oz of ballast can be traded for some good front end detailing.... Need to go light on the back though.

Cheers

Absolutely Simon, If you can keep it light now you're on to a winner :af

Hi y'all

Good to see some of the old names still here. I've started practicing for my 'B' licence with a newly built CAP from a Glens Models Kit. Very nice indeed. I designed and built a semi scale FW 152 Moskito last year. It uses a couple of the Lanc motors along with RAF pilot & co-pilot. My next project is going to be a Storch for an old RCV 60 which has been looking for a slim nosed home for several years now.

Keep the faith
Derek

Hi Dek,
      Good to hear from you, Yep there's still a couple of old pieces of furniture lying around here, struggling to get our Lanc's airborne for one reason or another :D
A Storch sounds interesting, have you checked out Neil's on line build? Take care bud.
Cheers Walts

Power setup "Plan B" looks like a non-starter. I can't change the gear ratio from 2.6 to 2.3 on my in-line gear boxes. So, I on to "Plan C" now. I just ran a test with one motor and a 3 blade 9x7 Master Airscrew hooked up to a single 15C 3s lipo pack. At full throttle I am pulling about 12 amps/ 120 watts and 5600 RPM. So I could get four 2000mah 3s packs in parallel and run all motors in parallel. This means I'll need a new speed control that can handle 50amps or so. But my total wattage should be up near 500.

The amps seem a bit high but I should only need them to take off ... or hang the lanc by the props ;). I could also cut the props down to ~8in, that should cut an amp or two out at full go and give me some more pitch speed.

So how does that sound for sanity?

Scott.

No good asking me Scott, I ain't been sane for years :D >:( :P :'( ;D

Graham, I believe that Ripmax lost the contract to distribute Eurokit retracts. I got mine from Galaxy models a while back now. So if you call them they may be able to tell you who is now distributing them, or they may even have some instock if your lucky. But make sure they are the new type as the design of the connectors is far superior to the originals i got :af

Hi Scott...and welcome to the Dark Side!!   :ev :ev

Gotta say for a madman Walts is talking some sense here.  Got my Eurokit retracts from Galaxy too!  Water slide decals I got made by a guy in Paisley (I live in the Highlands so hardly a next door transaction).  He made a great job of them and will try and get his address for u  :af

Hi guys
dusting my Lanc off for another seasons flying ...... I remember someone had a leaky retract valve & they used grease or something on the o-rings to seal it ..

Can anyone fill me in on on the gaps ?

regards
BD
