Take the pull start off, you won't need that. You'll need a drive hub and some way to secure the prop to the shaft--I'm not that familiar with buggy engines. Otherwise, it should be fine. Make sure you get a good prop and check the RPM's. Keep it around 10,000 and you should be fine. I would think it will actually run cooler on the plane than in a buggy becaues of that huge fan blowing on it!

Oh, one other thing, does the shaft on your buggy motor spin counter clockwise when looking at it from the front? If not, then you'll need to get a pusher prop rather than a tractor prop--which is actually just a prop made "backwards" that is designed to go on an engine mounted to the rear of the plane, but will also work on the front with a motor running "backwards" as most people use them with counter-rotating twins.
