95tequesta,

Maybe, but I don't think so. What did I say that contradicted something else I said? I didn't find any such contradictions in my postings in this thread.

You claim that "a fast pylon racer can utilize a cg farther forward of the center of lift. While a slower flyer will benefit more with a CG farther aft than that of a pylon racer". This does not make sense to me, contradicts what I have learned about stability, and, I think, is a false statement. Can you explain it to me in more detail so that I can understand it? I'd appreciate that.

Dick's claim that I disagreed with was that "1- If the plane is extremely light - the CG does not matter". This is not untraditional logic that works for Dick, it is simply untrue, and is an absurd statement. I'm sorry if that seems harsh to you. I may not have made the comment, except that this thread is in the context of offering aerodynamics advice to beginners. In that context, claiming that CG location does not matter for a certain type of aircraft is not an appropriate thing to do.
