The all up weight of the palne, based on stock power system is 20 ounces or 1.25 pounds.

I would sugget you shoot for 75 to 100 watts per pound for spirited flying. That means you want a motor in the 90 to 125 watt range.

One of these should work nicely if the plane has a stick mount for the motor

Or this might be better if you can't use a stick mount
