A OS 46AX or a 50SX would be enough. Anything bigger than a 61fx would be way over kill, but if you go with the 61fx, you might as well get a 91fx because they have the same bolt pattern and the 91 is lighter. Acceleration straight up is always impressive, but this might over stress the airframe. Just don't fly wot.
