The real plane has small wings that extend when the main wing goes to partial and full sweep. These help compensate for the center of lift moving aft. I added working invisible wings that sweep opposite of the main wing. This seems to help with lateral stability along with minimal down aileron travel with wings extended. The actual plane had a tendency for roll reversal at high alpha because the up stabilator would stall and the plane would snap over. Adding flapperons and increasing flap area hepled with slow flight too. CH 8 switch for sweep angles locking out ailerons(like actual F-14) at full sweep. This is a great looking plane and the tail snaps around in the turns just like the real bird!
