Thanks Ernie for you comment. One of the fellows at our field has said the same thing. Once I see if my throws are in the ball park I will reprogram the radio to use a switch instead of the flap dial. By the way you called them an airbrake. I called them flapperons, and then there are spoilerons. Does anyone know if there is a big difference between flapperons or spoilerons? I was wonding if they are just opposite or are they in fact just the same, and would both of them be considered an air brake? Jim Tucker
