Thanks gentlemen. I really appreciate the replies.
Thanks Baff. But this is a constant value. My issue changes depending on speed. At lower speeds, this FM responds exactly as I want it to. This P-40E isn't super-fast in angles turning, but in my estimation that reflects the reality. The P-40E was a steady gun platform. A slightly lower value in MaxControlSpeed makes this plane respond calmly and predictably to the stick, making it easy to establish a firing solution. Thus, a steady gun platform. I appreciate you offering a solution though.
Thanks Fubar. Turns out, this was it. I commented out this section from the elevator as a test and now the plane turns uniformly at all speeds. Now I can apply this to the A6Ms and get a realistic AI behavior.
Problem solved. Thank you.
