ill have to check the lateral balance...   the servo's are very very close ... my left elevator servo seems to have the very slightest hesitation at the very top end of high rates to match the right side...  but i could only notice that when I had 3 foot extensions on the elvators to make sure everything was lined up perfectly.   linkages are solid.   literally required no trimming.

it will still happen if I gradually bring back the stick more and more until all of a sudden it just snaps to the right...
