I know there was a thread in here about setting on mechanical differential for Ailrons. is it different from a shoulder wing to a low wing? I think I remember it correctly, for a left bank,,the right ailron has LESS deflection down compared to the left ailrons deflection up? Basically it takes more deflection to lower a wing that to make it rise?? and is there any advantage to using differntial in a pylon plane or just go equal throws. Also..I remember someone years ago saying to add a slight amount of "flap" to the plane to keep it from creeping into the pylon when on a knife edge..something about small amounts of flap cause the nose to drop?
Now that I have just confused myself[&o]

The idea behind using differential in ailerons is that the deflection of the control surface causes drag. If you reduce the deflection on the outside wing the plane will tend to pull toward the direction of the turn. The aileron on the outside wing goes down in a turn. Regardless of whether it is a shoulder wing or low wing, you want more up than down on both ailerons.

As for flaps, I wouldn't suggest using them for racing. Flaps are designed to slow the plane down. If your plane is creeping into the pylon on turns it is a often sign that the plane is nose heavy requiring extra up trim to fly level. Once the plane is turned on it's side, that extra up trim cause the plane to pull into the pylon.

IF you look at www.flyfastcomposites.com under Neme-Q setup, there are pictures that show how to set up mechanical differential.

And yes, a low wing is done the opposite as the shoulder wing in the example at that site.

Thanks Terry and Dave,,thats what I thought but just wanted confirmation.
