Ive been doing conversions for over a year now and besides being fun you have a sense of real accomplishment when ya go to the field and tell you can say your plane is flying on a weedie or saw motor.especially when ya say ryobi,echo,stihl,ect that everyone knows already.plus there cheap if ya find the engine at yard sales ect,but make sure they at least try to start.you could put a 30cc homlite or even a poulan 42cc on that stick.both are easy conversions and conversion parts are easy to come by.I believe av8tor just put a twin on his stick.maybe he will chime in.brillelli engines can fix ya up with poulan parts.heres a pic of my 24cc echo on left and a 28cc stihl on right.
