I can understand that, but I guess whats throwing me is why does it go up when spoilers are deployed, if its supposed to kill lift? Heres a pic to if anyones interested.
You're so short coupled that raising the big ailerons as flaps probably moves the lift/center-of-effort to well forward of the ceter of gravity. The surface area of your ailerons is probably about the same as the horizontal stab. Is your center of gravity on the 23% +/- distance from the leading edge? Your S.P.A.D. probably thinks it's a flying wing or delta wing because the empennage has such little leverage.
