Default RE: Flaperons on GP Slow Poke .40

ORIGINAL: RPM1

Ok now I am a bit confused again. Since the plane has a short coupled airframe and a wide cord the flaps were overpowering the elevator, essentially working opposite of what they should. I thought I understood that if I deflected the flaps up on the outbound portion of the wing it would essentially add "Wash Out" to the wing. reducing the possibility of tip stalling. Therefore you could increase the AOA. Where did I go wrong reading the posts? Feel free to educate me as now I am lost.
OK, read my last post again. Draw an airfoil if you have to. Draw a centerline through it.

Now draw it with the flaps down and draw a centerline as I indicated in the last post.

Wash-out is reduced incidence at the tips. If you have separate ailerons and flaps and deflect only the ailerons up, then you have wash-out.
