The company states the design goal of the AC-6 as a glider for the competition and training roles, even though it does not have provisions for water ballast. The AC-6 is a wing span development of the span AC-5M, with longer, higher aspect ratio wings terminating in

winglets Wingtip devices are intended to improve the efficiency of fixed-wing aircraft by reducing drag. Although there are several types of wing tip devices which function in different manners, their intended effect is always to reduce an aircraft' ...
