We are kind of getting off topic; but I think the term "aft CG" really doesn't mean anything. Aft of what? Each plane has an optimum CG for whatever you are going to do with it. But I am in way over my head here. I like the hands off inverted flight because you know you just have to do things lower and lower to the ground. With my limited skills, it makes things a lot nicer when you don't have to worry about a momentary slip putting you in the dirt. Besides, I love making a low inverted pass and right in front of the pits take my hand off the radio and scratch my butt But I see now that I am in for a lot more reading and practicing.
