I read plenty of discussion on RV7 vs RV9 (or 7A vs 9A), but here's a newbie question that I need to get a better handle on. Why a 7 vs 7A? or 9 vs 9A for that matter? Maybe start by discussing which is easier to takeoff and land. I have read that a 7 is probably better for grass strips because of less flip over potential, but what are the other considerations?
