This aircraft has been converted to electric using a Great Planes Rimfire 1.60 63-62-250 Outrunner Brushless motor, and a Mejzlik 28.5 X 12 narrow 3 bladed carbon fiber prop. This is a large aircraft, so It is flown on four 8000mah 8s LiPo batteries. (The batteries are configured to emulate 16s 16000mah 67.2V) which yields about 4 mins flying time. With proper throttle management you will definitely exceed 4 mins. 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.
