Very interesting observation, Ty. Next time out I will try to observe whether the nose-down attitude is greater with down elevator, although if the nose went down steeper with down elevator in an upright spin, I think that I would have noticed. Reversing the aileron deflection while spinning one of these birds slows the spin rate, and greatly slows the sink rate, as the airplane approaches a flat spin, and I will also test the effect of down elevator in a flat spin. Live and learn, as they say. Aerodynamics has a way of keeping a person humble.
