Hi All,

I've seen the Honda 31cc engine that's been converted to gas and would like to know if there are any larger 4-strokes that can be converted for airplane use. I'm trying to come up with an engine that is fuel efficient and can run for long periods of time.

Any information would be greatly appreciated.

Happy flying,

Jim

Look in the "engine conversion" forum. Search for "ryobi", "4-stroke", "4 cycle" etc. The Ryobi search will bring up a bunch of good threads on 4 stroke gassers.
