In the old days many plans had high camber for low ceiling and low
camber was high ceiling. The reasoning used was more camber made them
climb slower and less climbed easier. My aero engineering teacher in
college use to fly indoor free flight as well as a kid and he once said
to me all they were doing back then was adding drag to slow the climb
down for low ceiling. I also use the same airfoils on my high and low
ceiling models, I just use other factors to control height climbed.
