Most did not have flaps; however, the Sterling Yak and Mustang of the same era had flaps, as did several older designs: Nobler and Chief for example.

In PAMPA Old Time Stunt there is a 10 point no-flap bonus. I would like to build a British design called Lil' Abner. It has flaps maybe 1/2 inch wide and I can't decide if I fly well enough that losing 10 points is no problem, or if I fly so poorly that losing 10 points would nt be noticed.[&o]
