Actually, motor is from a string trimmer (weed wacker), and no airplane I currently have is really quite big enough to put it in right now. Am currently in the process of acquiring materials for a large SPAD to use as a suitable test bed. Haven't flown power for about four or five years, and only made a few sailplane flight in the last couple. Work and school have kept me off the flying field the last couple years. But I WILL be back.
