Thanks for the feed back,I made a little table to camper all suggested engines and as far as I can tell yes the OS has the less Hp. And is not the smallest on cc and is up there on the RPM. So this makes it more confusing. What should I look for when deciding on an engine for a go fast plane?? Also I have read that it is kind of difficult to get parts for the Moki is that correct?? I didn't want the fastest since I don't race I just want something fast to have fun and look good.Motor
