Hi,
owning (and flying) 5 helicopter from 26g to 3800g I am very interested. However I don't think it will be that simple in the end. Tuning a helicopter for normal flight is complicated as hell, so such a system requires much work to get it right. There are some ready systems on the marked evolved over the last years (Helicommand, V-Stabi, GAUI GU-356, Gyrobot etc) so I guess you tackled a problem which will keep you busy some years. Also check the mikro copter project!
Best Regards,
Carsten
