What would cause the flap sero to opposite deflect and then set itself properly when the TX engauges. I.e., when I turn on the RX the flap servo deflects all the way one way. When I turn the TX on it moves where it's supposed to be.

I have the Flap INH to use with the 3 way switch on the upper left. I know this is probably a simple fix, I just can't think whats causing it right now.

If anyone knows, I would appreciate the answer.

Thanks,
Andy
