Hi what is the prefered cg setup on a 33% aerobatic plane i guess somewhere between 25% - 33% of wingcord is in the safe margin or do you go further back than 33% for 3d flight.

this is easy, keep moving batts back until at 1/2 throttle inverted the plane flys straight and level hands off. this balance point will be very close to airplanes neutral point. all 3d stuff will become easy, however, regular flying and landings will require lots of stick work and become more difficult.
