Flarz--that is a good option. I like that style of plane and flying.
Ahicks--my engine is an RCGF 25 (if I have the lettering in the correct order). It pulls arount my quater scale cub ok, but I am tired of the plane. Starting to get a little beat up also. I bought this engine after getting burned in the Brilleli Engine bankruptcy. I had sent him a check for an engine that never arrived, just some legal paperwork if I wanted to join the bankruptcy proceeding. Not many folks probably remember that issue. The RCGF seems to run just fine. not sure what I am tacking on an 18-6, but definetly not lugging down.
