I have a Venture50. I dont think your problem is in the motor unless you have a compression problem. The 32 flies the venture with a good climbout. I on the other hand went to the OS50. It really makes the venture fly. I have a long boom conversion on it so it can run 600mm blades, using TT carbons right now. The one problem with the 50 is the throttle curve. It will take awhile to get it set, to much power have to calm it down alot. I used a GV1 to solve that problem.
