Thanks. The longer this runs the more knowledge that comes along. I have never used flaps so the ones on the P-40 were not used and were made to not work. I am now building a Great Planes Cherokee that has flaps that will be used as a training aid. When I get used to flaps I will fly the P-40. This is a work in progress and one of the reasons to enjoy RC.I have a simulator but it just doesn't seem to give total real life playback.Time will tell.Flaky is an excellent term.
