I've got the KE figured out. I did the same, radio mix with a bit of up elevator and little RH aileron. Knife edges perfectly now. Couldn't be any better. But hovers are a different story. I wants to pull the the wheels and when you give enough up elevator it wants to flip over. Very difficult to control. Also makes pulling out of a hover hard because you are pull against an up elevator which causes drag. I think a bit of up thrust will help. At least that's what I'm gonna try. Another maneuver this plane does well is rolling circles, the easiest and prettiest I've ever seen.

Thanks
