For the persistent but aerodynamically challenged:

Flexing an aileron upwards makes ''lift in a downward direction'' along that portion of the wing, and that's half of what banks your airplane (The other aileron moving downward and increasing lift on that side is the other half). With us so far? Good.

Flexing BOTH ailerons up makes ''lift in a downward direction'' along the portion where the ailerons are located on both wings simultaneously. Still with us? You sure? Great, you're almost there, so hang on.

With both ailerons flexed up part of each wing dedicated toward making ''downward lift'', and there is less wing on each side still making ''upward lift''.

There is no way, none, that an aircraft in this configuration has a lower stall speed. That. Is. Physically. Impossible. It may indeed be flying more slowly than without the reflexed ailerons simply because of the extra drag, but the stall speed is higher. Not lower. Period.

Sorry, I'm not picking on anyone. I promise. The physics just is what they is.

If I learned anything from the now infamous ''Downwind Turn Myth'' thread though, it's that some will deny the truth at all costs rather than even contemplate the possibility that they have been operating under false impressions or assumptions. Them folks just is what they is too, so God bless 'em!
