RE: FEJ L39 1/7TH
i had first generation 1/7 l 39 from fly eagle
rated at 19 lbs not so mine weighed 25 and with fuel almost 29 but this was first gen build it light you should be ok also fly it in dont glide it stay on power i made mine a submarine quickly hopefully new kits are much lighter this was 2008 though thought i would never order another fly eagle but then again the improvements have been excellent now i have 2 fly eagle and ready to buld the small viper f e j cant wait good luck guys |
RE: FEJ L39 1/7TH
This thread reminds me of Todd's recent similar attempt to obtain info (without much luck).... So let me kick this off.
This one time, at band camp, I talked to a guy whose brother's friend had one of these planes, or maybe it was another one, I'm not really sure. Either way, it had a turbine and servos and he really loved it. :D:D:D Jim |
RE: FEJ L39 1/7TH
gtoro26,Thanks for heads up.I'll weigh mine empty no eqipment / fuel.And again when it finished with fuel.My kit arrived December 2010 just 6 months ago,don't know of any design changes since then.I have 3 FEJ jets. L39,F14 twin and the new L viper on the way.Yes I have the fever.

RE: FEJ L39 1/7TH
Just finished checking the weight.This result is with the gear and every thing that came with the kit,hardware/pipe etc.
RH main 7lbs 5oz LH main 7lbs 6oz nose 5oz - 22 lbs Need to add engine,servo's, batt etc. I have an old P80(18lbs thrust) new in the box and wanted to use this engine.I may have to rethink this now. |
RE: FEJ L39 1/7TH
might have same issue
plane with p80 and electronics can possibly be up in 25 26 dry it will fly but with mine it was the plane flying me not me flying the plane it was more reaction to what planes tendancies were best of luck i have spare gear if you need good shape |
RE: FEJ L39 1/7TH
i flew it with a rabbit and it pushed it nice
no issues with turbine it is fresh from service with no time i am selling it with my elan but if you want it 1800 p 80 is a big can also response time might be issue on landing need the acceleration |

RE: FEJ L39 1/7TH
with 120 it is same can as p80 on the heavy side
i think even p80 is too much engine make it light fly better gear let me check if my builder still has them no upgrade but it was first gen i never had issues i can sell for 100. 00 shipped let me know gabe 3056076535 |

Mine is first generation (over two years old). The plane is 10.5kg with full tanks. Engine is wren supersport.
Flies great, glides well at that weight. After all the mods I made, it's a really good plane. Yann |

RE: FEJ L39 1/7TH
So you gents think my old 18 lbs of thrust P80 will fly a 25-28lb new FEJ L39 well?
|
RE: FEJ L39 1/7TH
Thanks. Very effective and convenient for maintenance.
The only issue I found with this brand is they sell their products as ARFs... while they are not ! |
RE: FEJ L39 1/7TH
at 28lbs, your plane is on the heavy side for sure. It should fly OK, but watch your airspeed.

Oh god !!! that was the question I didn't want you to ask...
On the fuse: Changed the rudder setup. Changed the thrust pipe for a wren pipe. Removed (easily) most of the formers, to change them. plywood was not up to my standards. Changed the turbine beams to suit the small footprint of my wren. Wings: Custom made new springs for oleos (absolutely necessary) Changed O-ring brakes for regular rim brakes. I could not brake evenly with stock ones. Changed most of the servo pockets as some of those parts were missing from my kit. So I dit it all over, my way. Modified flaps setup as well, to allow more deflection. Modified main gear doors my own way. Still don't understand how FEJ wanted me to do it. That's it for the most important parts. There is more, but that was more on the cosmetic side... |

You see how the plane stands higher off the ground with custom springs?
Few more shots of flap setup. |
RE: FEJ L39 1/7TH
Also main retract bay has been heavily reinforced with carbon fiber after the first fight (after the pics were taken). The stock wood is far from perfect and cannot be removed.

RE: FEJ L39 1/7TH
OK, so you're good with the formers. Yes, I might be able to provide you with a set of spring the stock springs are way too weak.
FEJ, at the time I asked, was not able to provide different stiffness of springs. The flap mod is very important too. It lets you come in much slower. A friend of mine had the same plane without the mods. He was coming in mch faster. |
RE: FEJ L39 1/7TH
Yann,
Thank you for the springs,how do you want to work the payment?.Is a USA check OK? I don't have paypal but a friend of mine does,I have to talk with him first. My kit is a pro kit so it came with all the flight controls installed.I don't want to cut the flaps right now.We have a large paved runway at the club so a slightly faster landing would be fine.But it is something I may do after I get a few flights on her,they just look cooler they way you did yours. |
RE: FEJ L39 1/7TH
Let's find out first if I get you a set of those springs first. We'll figure out payment after.
I don't even remember how much I paid for my set... |
RE: FEJ L39 1/7TH
That's fine,I should have worded it differently.But if you do find a set around I'll buy them from.
