Thanks for the guess. It's interesting to see what people think might be similar examples, and it's always informative. But do you wonder how well those speed planes do aerobatics? And if they might just snap easier one direction than the other? Like on takeoffs with different wind directions? Wouldn't you guess that they'd suddenly snap on you sooner one way or the other in just about any situations that're different one way from the other, like inside versus outside loops or loops upwind versus downwind? It's been fairly well documented that this little Ultimate will surprise you with unexpected snaps.

Keep in mind that one point of this thread is that it's dead simple to configure these 4 different ailerons to operate all the same.
