Ok, I'm going to ask a question about Joe's set-up now for my own education: is it a good fix to separate the elevator halves and actuate them with 2 servos to achieve differential trim? All other options except CG perhaps are closed since wing and stab incidences are fixed. Please am I missing something else one might do in this set-up to improve upon the stated OP problem? Thanks for this terrific discussion, you guys Rock!
