You'll be amazed at how well this airplane flies with my setup. Knife edges are almost effortless. If you have enough skill it will even hover.This 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 a more usable AS3X flight stabilization. This allows both beginners as well as more advanced fliers to take advantage of this aircraft. Enjoy. Please rate and comment so that I'll know if I'm on the right track with my setups. If I am, I'll keep doing it. If I'm not, I'll take your suggestions to make things better.
