        Q: Will it fit a 540 motor mount?
        A:
        No, not as is, but you could modify the motor mount easily by drilling a couple holes. Or you’d need to make one of the holes on the current mount into a slot so that you could move the motor closer to have contact between the pinion gear & spur gear
