Hello,

O.K. you 90's Fun-Fly plane guys... I need your opinions.

I've been working on a Fun-Fly competition plane for a while now and was wondering if a 4-stroke engine could give the same performance as the 2-stroke engine with a pipe. Most of you guys, at that time, were using the latter set-up to power your planes. I'm not looking to compete, but would like the same or better performance. Do you think a 4-stroke would be comparable?... better??... or worse???
The kit suggest a 25-35 size 2-stroke engine with tuned pipe. What would be the 4-stroke engine equalivant?

Thanks,
Phil
