Just the American way: more, bigger, faster.
But then, full size airframes are no different. You never see a Mk II version of a fighter with a lower speed or weaker engine.
More power! Yeah, that is what I mean!
Really though it all depends on what one determines is more power. For me you really gotta go crazy on the HPs up front before I consider it more power. For instance, putting a 120 on a 46 size airframe is totally overkill in my department, but a 55AX on a 46 size airframe is perfecto!
Now let me see if maybe I can fit this DL50 on this 40 size Twist [X(]
