Default RE: H9 Showtime 4D electric conversion

It's not about the motor, it's about getting enough Watts through the motor. Any of the motors you listed will work if they can handle the kind of power necessary to fly the plane in a fairly efficient manner. In your list, the only one I'd doubt is the smaller Actro.

The plane should weigh in the 9lb range, which means you need 1350-1500 Watts for full 3D (that's 150+ Watts per pound) performance. On a 10S LiPoly, that's in the high 40s for Amps, something like 46 or 47 Amps. All you need to do is get a motor that will handle a 10S LiPoly (or 32 NiMH cells) at 46-47 Amps, and prop it to draw that much. You'll be in pig heaven

Of the bunch, the AXi is the most cost effective.
