RE: Retrojet 75 Turbine trainer
Very nice.
I'm building one now with a Wren 70 fitted.
The extended flaps / air brakes look very effective.
Looking forward to completing mine.
Cheers,
Pete

Today i Maiden the retrojet, just a few clicks of trim and it flew hand off, little bit windy, but it flew very steady, trainer indeed. Video http://www.youtube.com/watch?v=av3idOuACHQ Viggo

Can't believe how quickly it took off
Nice flying as well.

RE: Retrojet 75 Turbine trainer
Thanks for sharing the video. Congratulations to a happy maiden! It really flies like a trainer as far as I can see. I am going to stretch the nose about 100 mm and mowe the turbine forward about 70-100 mm compared to the plan. I will probably also decrease the downward angle of thrust slightly. I think....

What kind of main and nose landing gear did you use Viggkri? Did you make it yourself or did you buy it of the shelf? If so, where?

Viggkri,
As a matter of interest, did you fix the tailplane and fin in place before you covered the fuz?
I mention this because there is balsa quadrant glued around the bottom of the fin.

RE: Retrojet 75 Turbine trainer
Viggkri,
Thanks for your reply.
Sorry to hear you had a heavy arrival because of the elevator failure, but guess you will be airbourne again shortly!
I'm not usually keen to film cover a fuz with the tailfeathers in place, as it makes it more difficult to make a neat job around the fin area, but in the case of the Retro jet, I don't think there is any alternative.

Viggkri,
How did the test flight go? Hope all went well.
We went to a Large Model Association meeting / trade show here in the UK yesterday And there was a Retrojet being flown there - very impressive performance for this type of model.
Hope to complete the build of mine when this extreme heat subsides here in the UK!

The testflight went great, it was a bad crosswind, but i got some help with it, one flight today as well, no wind, perfect.
The covering on the underside cant tolerate the heat in the long run, so i sheeted it with aluminium.
Soon redy for 3 weeks vacation, hope too fly it a lot.

Update: I have 4 hours on the Retrojet so far ( 30 flights) for me it has been a perfect trainer, it build confidence for the flights with my Elan, i have flown 10 flights with the Elan this summer.
The nose gear must be strong, it take some abuse on bumpy fields, i have changed mine too a heavy duty Thunder Tiger nose wheel asambly.

Vid I caught at the weekend of this docile jet trainer...if you fancy something slow and stable that's pushed along by a kero burner I'd say its a good option...also has an amazing short take off capability...literally took 5 feet on the first flight I saw
