I just built a Bruce Tharpe Flying King (the smaller one). I have powered it with a TT 91 4S. Battery is about center as are the servos. According to the plans the CG is to be located anywhere from 4" to 5" behind the LE of the wing. I set it up as indicated. The plane took off just fine, but at full up elevator there was no way it would loop. I know other members in our club who have this a/c and they claim it will loop at 1/2 throttle. I can only conclude the CG on my craft must be wrong. Any ideas??
