Why do you think I am "pissed" at you? AF

By the way, Cm_de (that is, pitching moment given an elevator
deflection) is nominally negative. So, you can see, a positive elevator
deflection results in a negative pitching mo

In every aeronautical engineering publication I've seen, the
convention for "positive" has been:
-- Positive aileron deflection creates a positive rolling moment,
positive around the +X axis, i.e. roll to the right;
-- Positive rudder deflection creates a positive yawing moment,
positive
