The aircraft has been balanced and tuned to fly exceptionally well with no trim, by adjusting the CG, tuning the incidences of the flying surfaces and the motor, adding mixes and applying AS3X flight stabilization. I've used an O.S .55 AX ABL 2 stroke with a 12 X 8 APC prop, which yields much better performance. I've been able to correct just about all the bad characteristics of this aircraft. It will hover, and you'll be amazed how well it holds it's attitude, whether right side up, inverted or during knife edge flight. On landings, just line this baby up with the runway, chop the throttle all the way down, and watch her land herself.
Enjoy.
