New problem to watch for in flight... I see a "twist" in the top wing at moderatly high speeds, where the leading edge on one side catches the wind and dives and rocks the top wing out of position. When you have this happening, drop the throttle and it will let go and fly right. When it happens, the ailerons won't make the plane respond to roll commands. It took mine in, and it looks like it is due to the weak center cabane, allowing the top wing to twist on the Yaw axis.
In "speed dives" my HR will roll right pretty severely. Backing off the throttle and getting the nose up restores control. Scared me pretty bad the first time it happened since I fly in my cul-de-sac surrounded by 2 story houses. :O I don't blame the plane design though; it was clear I flew my lightweight plane out of its envelope. I was thinking that maybe it was that 10x3.8 slow prop bending under the stress (I can't see it with my own eyes of course). I'll watch the wings next time to see if its the wing twisting.
