I just googled the motor, and holy cow, talk about over kill.

400 watts, with 550 watts for 30 seconds, up to 24 volts.

What's the capacity of your battery? You might want to make sure you don't pull too much current for it.

One thing you might not realize about electric motors, if you put a larger motor in to a plane, but keep the same battery and prop, the performance won't really change unless you previously had a really under-sized motor. Sure, there are differences in motors, but they are fairly small compared to the differneces in batteries.

I suspect that motor/controller is heavier than what you have now. I'm not sure you'll get enough extra power to make up for that extra weight.

Anyway, you won't smoke anything, so yes, you can put that motor in your plane. I bet you don't get a noticeable improvement, and you might get a performance drop. Put a bigger battery in there like a 3 or 4 cell lipo and that motor makes more sense.
