i have it balanced right at the recommended cg, 4.5 inches back. one other thing, when i was trimming it, it needed alot of up elevator to fly straight. i used a xoar 17x6 prop. i could put the apc 17x6 back on, i know that prop is heaver. other than that i got everything in the nose all ready other than my rx, i think my wires are too short for that. i could cut out my servo tray or the cockpit floor/ pilot to get weight out of the tail. i was really trying to do everything i could to keep lead out of this plane, maybe i will have no choice. maybe i will just need to put a dle 30 on this plane
