That is a speed 400 motor. Anything over 15 amps should be adequate. 20 to be safe. Motor should actually run about 10 to 12 amps.

Side of box says 7-9 cells which would be NiCd or NiMh cells. That would be 8.4 to 11.8V. 2S to 3S lipo should work.

I am going to guess a 9X7 prop.

I would use a watt meter to insure that you are not pulling more than about 12 amps or you will burn the motor up pretty quickly.

I would recommend using LiPo batteries. Much lighter than NiXX.

This will work for 2-3 cells lipo

I don't know what kind of room you have in the plane but I would suggest something in the 1200 to 2100 mah range, depending on the plane and the space available.
