OK, there are no flap surfaces, but it is an asymmetric airfoil. The "upper" part of the airfoil faces left and a little down, producing right yaw and a little pitch up in forward flight. I think it also has some incidence. I should be able to make this work, starting by making the dihedral 70 deg. It's all academic at this point though, since wings are ignored on helos ATM.
