Flight performance Flies really well and has plenty of power with the 4 geared Speed 400 motors. Will ROG (run off ground) on grass with a fairly short take-off run. Climb at a comfortable speed is approx. 15°. I haven't tried any aerobatics as it isn't really designed for them, but I will explore some later

21 Jun 01 - I bought this model at the same time as the Twin-Jet (on 2 Jun 01). I have built this exactly as intended with the only variation being the fitting of different servos and speed control. I decided to fit the optional gearbox sets which allow ROG (run off ground) from short grass to save hand launching from my normal site. The first flight was fairly uneventful, but the elevator did need a lot of down trim initially. In the instructions it warns that some down elevator trim will be needed at full power, so I set-up a mix. Having adjusted the mix in flight, I found that it needed almost as much down trim at half throttle, reducing to nil with the motors off. On my JR set the mix values are 0 - 15 - 20 elevator at 0% - 50% - 100% throttle. I will be making some parachutist and parachute load pallets to drop on my next flights.
