I'm kind of new at this. I'm actually Ku's Dad. We bought a small seaplane called a Glassair Sea Easy 1/2A ARF. It call for a .061 - .074 motor. I would rather have more power than less. I am not at all familiar with these small engines. Can someone recomend a real slick motor for this plane. Price is not much of an issue in this case. Are there 4 stroke motors this small ? Which manufacturer has the best quality? Thanks a bunch. Ku's Dad.
