I have a vintage build, Kwik fly 3 currently using a period correct .60. However, the 40 year old finish is really taking a beating from the glow slime. I was wondering if the new Evolution 10GX or 15GX would be a sensible gasoline powerplant for this model, or would it lose all its nice flying qualities? I also have an old Bridi Trainer 60 that looks like a good candidate for one of these engines as well. Anyone else gone this route for their vintage plane?
