Just fly it around with out using the flaps. If you operate the flaps with the ailerons, (like a long strip aileron) then start using the flaps and ailerons seperately the plane will fly different from what you are used to. The plane flys just great with the flaps up and the small ailerons. When you start using the flaps, try them out and get used to them 3 mistakes high. The plane will balloon up, be ready for it. If you have a computer radio, you can dial a little down elevator in with the flaps to counter that. Have fun.
