Ok so i have this rv9 450 almost back together and on its maiden my flaps were inh and my dr expo was totally wrong. So on its next maiden i was thinking im gonna put a little flap in it and make sure dr is right does this sound right please advise.
I'm not quite sure what you are asking as I never saw a question in there. But flaps are for landing and taking off. They are used to slow the plane and provide more lift toward the center of the plane so the center of the wing will stall last.
