Mine was with the TT46Pro only, more than enough power. Try your 46AX on an APC 11x5 or the standard 12.25x3.75. Only thing about this plane is that being your first 3D plane you will notice that the plane can fly really slow. But do not get so slow that it stalls. This plane bleeds speed much faster than your standard aerobatic plane, so be a little careful on the final approach. When I first landed mine I was almost short!
