hiya all,

Now after having such a great weekend at the WMFC fly in with some of the LMA guys, Doug very nicely let me have a fly with his L39......

So now i'm hooked - well the wife says its ok - and although i'm not in a position yet to go spending that kind of cash i'm one for having a good look around and getting as much info as I can.

Several people have recomended Wren for the turbine so i'm going to go down for the open day this month - hmmm might have to leave the credit card at home though :)

Now then any advice would be very welcome :)

Regarding the engine selection, then Wren are a good choice, as are JetCAT.  I would go with whatever is more popular amongst the chaps you fly with.  I went with Wren because they are only a few hours up the road if I have any problems that I want to resolve pronto.

Have a think about the model you are going to go for too.  I went for a Boomerang Intro, and then a Nano, purely because it was the only model I was confident of being able to operate off my normal 45m grass strip.  I was quite surprised at the flight envelope though, on low rates it is really docile, and I reckon anyone who can fly a normal trainer could cope with it.  Up the rates (and the throttle!) and it is surprisingly aerobatic too.

If you are ever passing the Rhyl area in North Wales, give me a shout.  You are welcome to have a flight of my Wren 44 powered Nano.

Cheers

Hmm thanks for that Andy,

what do you do with Jetcat re - servicing then ?

Also would you recomend a boomerang type trainer over going straight in ?

Cheers,

I think for jetCAT servicing, the engine has to go back to the JetCAT HQ in Germany.  There have been reports of it taking quite a while for servicing in the past, but I have no idea if those comments still apply.  I have also heard of some UK servicing agents, but again, I don't know if they are authorised by jetCAT or not.  If you are considering a JetCAT seriously, then it might an idea to have a word with Ali M. or Dave Wilshere (jetCAT dealers).  they should be able to answer your questions with first hand knowledge, instead of my outdated knowledge!

Regarding the airframe choice, then it depends what you are after.  For me, the biggest consideration was my regular flying site.  It is grass, and not long, so I wanted something that was sure to cope well, and be a bit aerobatic too.  The boomernag fitted the bill nicely.  If you have a decent flying site, then you might want to consider one of the more "sport" type jets, like a Harpoon/Rookie, or Reaction or similar.  They are easy to fly if you have a bit of flying experience.  Going for a highly loaded scale jet is probably not the best idea if you are not a competent pilot, or have concerns about getting used to operating a turbine.  If you are unsure, then paying for an afternoon at one of the Jet flying schools is well worth it.  you can get a feel for turbine flying, and see how easy it is to operate a jet.  If you find that dead easy, then you could consider something a bit more advanced :)

A good compromise between ease of operation, and scale-ness, would be something like the ViperJet 2m for example...

Well we have a very long grass strip with no major trees etc.

I found Doug's L39 very nice to fly - and his U/C system works a treat for me. So when I go scale I think that would be a consideration

Like you say though its the learning curve. Might have a look into the jet days though...

If you have the good flying site, you can pretty much choose the model to suit your skills then.  Operating a turbine is not difficult at all, you just need to familiarise yourself with it, and get used to it.  It is perfectly possible to do this on pretty much any aircraft, but the models like the boomerang that have excellent access to the onboard equipment, make it so much easier.

That said, with a decent flying site, I would sell my Boomerang, and buy something much more stylish :)

I think Paul Heckles is the only guy to offer Jet Training, he is certainly held in high regard in the jet community.

I have both jetcat and wren turbines. My jetcat was away for 3 weeks when it went for service, which was all handled through Al's Hobbies. I haven't sent my wren away for service yet and any problems I've had with it, have been sorted without having to send it away. You can't really go wrong with either, but they say  a P80 would last you more models as a supersport has less airframes available to suit it.

There have been quite a few changes at Wren lately, so I'm not sure how/if things will change at all. Sara was always very friendly and helpful on the phone, her replacement is a bit different to deal with  ???

Which ever way you go, if you get the right help and advice, you will love it and find it very addictive  :af

Personally I've been chugging a fixed U/C Boomerang around the air now for a couple of seasons with a Wren (54 and lately a Supersport) and to date I would say the following:

Boomerang makes a great Jet Trainer with easy access to the turbine and installation of the various bits. Getting your head around the turbine installation was the scariest bit but in reality it's all very logical and simple.

The Boomer will fly of grass and tarmac with no problems.

Undercarriage mounts supplied with the kit are made of matchwood though. Beech replacements work great.

Once you are set up Jets are easy to run and maintain, fuel and go most of the time (make sure you get a decent fueling system).

Service from Wren has been great, a problem with the 54 was rectified and the engine serviced and sent back within the week. Cakes weren't bad either at the Nationals.

Supersport's drink fuel a lot quicker than a 54.

Can't wait for the Boomer's replacement to turn up and go to the next level of Jet flying. Hurry up Ali and get the ship to dock sooner :ev

That's what the throttle stick is for, flying jets has taught me that there is more to a throttle stick than "on" and "off"  :ev  :af

I've just replaced the fixed gear on my Nano, for some trailing link struts and retracts.  The fixed gear worked fine, but it must be adding a lot of drag to the airframe.  Hopefully being able to retract the wheels will make it slicker through the air, and the trailing linky-ness will make my landings look good again!

Throttle Stick? I just use the 3 postion switch, STOP, IDLE and GO, never could get the hang of this new fangled proportional equipment, next you'll be telling me the rudder isn't only for keeping it in a straight line when taking off.  ;D

Super Sport's give you more thrust than the 54 so it's bound to use more fuel.  :nananana:

All excellent stuff thanks guys.

Where do you get your fuel from ?

I think I'll go to the Wren open day and have a think, Paul Heckles is quite a way from lincs so i'm not sure a day would work - i'd be to tired to take much in I suspect.

Like I said - i'm planning on taking this easy and I need to get rid of a couple of models first anyway to free up some cash :)

Although the Wife is happy enough with the Idea...  :uk:

Fuel comes from B&Q or any other hardware store (paraffin), or sometimes you can get Jet A1 from an airfield.  :)

The Wren open day is a cracking idea :)

AS for fuel, I have two suppliers.  One is a local oil supplier (Caldo Oils) where I buy premium paraffin in 20 litre drums, and the other is a local garage where it is available in 4 litre containers.  It is not the cheapest fuel, althugh I prefer that to heating oil/Jet A1 as it has hardly any odour at all.  Just the ticket as I often sleep in the Van I transport models in :)

As I said before, if you are passing North Wales, you are welcome to have a go of my Boomerang/Wren 44....

Chris, if you can get over to just the other side of Stamford you can visit my strip and I'll talk you through it and maybe let you have a go on the sticks,

           Chris, i have sent you a PM.

                  Hi Gary are you all booked in for scampton ?

I have had mostly Jetcat turbines in the form of 70's, 60SE/80/80SE/120, but now also have a couple of Wrens. I have a 44 gold in a hack model . . . . which was giving me grief today! and the Supersport is just being fitted to a Boomerang Nano. I have to say that i find the Wren electronics quite basic when compared with jetcat, they do the job but i prefer the jetcat electronics as they do offer many more options and test facilities, much more user friendly. Boomerangs are a safe bet, all fly well and seem to be very tollerant of engine choice and would be my first choice. My own preference with regard to engines would be Jetcat . . . . loads about and are well supported, unfortunately if they do decide to play up and have to go back it can be 3 weeks or so before it is back, may be sooner if your lucky.

Mate there's a complete Boomer and turbine on the BMFA now. Seems a pretty good deal

I wanted a quick to build airfarme and did not fancy the Sprint, i like the proportions of the Nano and have seen on RCU that several people have fitted the SS so thought i would give it a go . . . . . certainly wont struggle but will not be using all the power unless for vertical manouveres and take off, would be too easy to overload the airframe.

brand1068

Thanks for your reply fellas.

Talking to a club member about a p80 turbine - now just need to look for a boomer then.

Had a real Eek moment when I saw the retract prices on Al's though... might leave the gear down for a while...

Have a look at digitech turbines for retracts/struts.  I picked up a complete set for my Boomerang Nano for less than £300.  Still not exactly cheap, but they make the models fly nicer :)

Hi Chris...


Could you not get a set of Springairs in and talk to Unitracts for a set of oleos? I might be a bit outdated, but Springairs were about £150 for a trike set and Unitracts would probably charge £30 ish (maybe less, maybe a but more) for a pair of custom made oleos.

......just looked at the Springair website and a set trike gear is $160. (300 series) handle 15lb models. If you want bigger, then they do a 400 series which would go upto 25lbs ish.

I have ordered direct before and had no troubles....you will probablt have to pay VAT upon arrival in the UK...but still makes them less than £150.

Just a thought!
On the build list...P-40, XP-55, Do335!, Grumman Goose, F4F, A-20, Me109e, Cougar, TSR2, Beaufort, Yak 3, Hurricane, Gee Bee R2, Super Sabre, B-58, P-80, Seafire

Ok starting to get (or should that mean BE) committed.

Have a Jetcat P80 arrving at the end of the month  :af

Now need to find a 2nd had airframe if poss otherise it'll have to be a new one.
