Freebird, I flew my plane with a rossi .40 for a full season before I added the 46ax. I had everything in the stock locations for the rossi .40. I had the three servos in the belly just aft of the spar. I had my battery and RX in front of the spar.
Are you saying that you plane is very nose heavy? where is it balancing right now? I had my balanced about 1/2 and inch behind the spar.
