RE: Evolution 10cc gas engine
I visited the engine forum and the evolution 60GX is equivelent to a 40 sized nitro engine.
A tuned exhaust should significately boost performance but not enough for a 60 sized Classic Pattern Plane. I imagine a .90 (15cc) sized engine would be the ticket for Classic Pattern.
The new Os 95AX converted to gas would fit perfect. I've thought about buying the Evolution 60GX conrod just to see if it could be used on another engine.
