Pete: Sorry for the confusion but sometimes my fingers don't
say what I'm thinkin. No I don't warp the aileron but raise the
full length . This practice is best used on planes like the P-51,
AT-6, etc. where the ailerons are short sections but even on
longer ones I haven't seen much difference.

Point of warning !! This helps control the plane at stall
speed at landing but is not a cure-all for bad landing habits.
You still have to have good low approach and enough speed.
This washout isn't going to help if you dive in at the field then
flare up to about 4 or 5' then the surfaces guit flying -- there's
nothing that can help then other than a trash bag.
