RE: Flaps or flaperons?
slipping a stearman or cub was never used to slow the plane. it was used to lose altitude with out gaining speed.,,,these earlier planes didnt have flaps so the only way down when too high was the side slip.500 hours in a 450 stearman and 100 in a clip cub made me into a real expert in slips. i have a goldbergh cub that fly great with a .40. it has been modified with flaps and has no problem landing. one intersting thing is that the N number decal was the same as my stearman,,,N-4734-C,,,scale aierlons on a cub should be set up with diferentual to corect for adverse yaw.,,,also true cub aeirlons on cubs and stearmans do not work at all in a stall. not thast that matters in a model. my sig 1/4 cub flys OK with a fox .60.,,,also,,,cubs fly fine with the door and window open.
