This is probably the best flying Edge 540 you'll ever download. 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. 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.
