I currently have a Wing Dragon 4. For anyone unfamiliar with it, the Wing Dragon is a 4 channel pusher prop trainer (From hobby-lobby). It has an 8 cell nimh battery (9.6v) and swings a 7 inch pusher prop (I don't know what pitch). I have flown it for a while, and would like to put a more powerful motor in it.

I have the option of using a friend's Neumotor 1110/2y/4.4 (4.4 is the gear box ratio). He also has a 70A Jeti Speed controller.

How do I tell if I can use my current battery with that motor and speed controller, and what prop do I use? I can't go bigger than the 7 inch prop, as there is no more room, and it has to be a pusher. Will that hardware work?

(I know I might be better served by building/buying a new plane, or using a different motor, but this option would cost me almost nothing, so I'd like to know if it's possible.)
