RE: CG Super Chippy
Never in 45 + years "suffered" from an "underpowered" plane. I have however learned a lot more from flying marginally powered planes , than high powered heavyweights . Better to learn the wing than expect an engine to make up for mistakes. BTW, I admit to having some planes with a lot more power than needed. Low power is how my father and brothers taught me to fly however. I am very glad for it.
Don't know if I could ever say "You don't want....." ??? I know what skills some folks could sharpen though !
I have indeed owned a few Chipmunks. Light planes fly great IMHO , even with a litttle less power.
Lest we forget the original question. Yes, the 55 is enough. Overpower anyone can do.
Define "easy"ou can modify for a heavyweight engine up front at any tiem. Learn to fly it light and you may not care to put a brick in the nose.
