P.S. Further thoughts:
Lee wrote: The left wing at stall attempted to drop radically to the left. The pilot gave a full right aileron movement and that kept us straight and level. When you look at the aileron action on a Coupe, the downgoing aileron goes down a moderate distance then comes back up when the yoke is turned still farther. The upgoing aileron goes up, up, up, WAY UP. Compare the upgoing aileron with the spoiler surface area and angle on a sailplane - the kind they sometimes use instead of ailerons. The Coupe upgoing aileron area is massive and the angle is as steep as any spoiler I've seen. I'm thinking that it'd be pretty hard to overpower that upgoing aileron and hold a Coupe in a spin. Also, you'd have to keep the high angle of attack to keep the inside-the-turn wing stalled. By its design, if you even hold the elevator full up, the elevator should not have enough authority to hold the plane at a high enough angle of attack to maintain a spin. If you relax the up-elevator, I suspect you'd pop immediately out of any kind of spin. Out of CG limits conditions invalidate the design.
