I'm in the process of getting my CMP 140 sized P40 ready for flight. Ive been braking in my super tiger 2300 and its starting to run smooth and reliable on the ground. Before I fly though I need to find out where the CG is for this plane. The instructions that came with this plane are for the 50 sized model and they say the balance point is 90 mm back from the leading edge. Does anybody know the proper CG point for the 140 sized version, I marked the wing at 90mm and is looks way to far forward.
