Sorry, Left out that important bit of info, they are barn door type ail. Essentially if I get what you are all telling me is it would be better if they deflected up not down to get the desired effect.

FYI The .40 has ail. from the polyhedral break to the tip. there is not a lot of polyhedral on this airplane just a couple of degrees, it does have a flat bottom wing however.
