RE: Fidgit contest plane pics
I just cobbled together this thing out of scraps so that I could get a handle on how this might work. I balanced it at about 12% and when the AOA of the upper wing is increased, it climbs and vice versa. It does roll when the AOA of each side is different from each other, but it requires much more up than down. I would think that if you want to turn effectively that you'll want to increase the AOA of the opposite side from the way you want to turn, rather than decreasing the AOA of the side you are turning to, or it will dive.
