You won't get rid of it on the H9 Edge. i use about 1/4 inch spoileron with 50 degrees up ele. (rear mounted ele servos.) it is a horrible thing to 3D, however i think if i invest in a load more power i could have it hovering very happily!
I'm using an MVVS 1.6 gas... plane weighs 12lbs... no vertical performance whatsoever. This model taught me to harrier, but at the same time scared the hell outta me! Worth it though!
Keep practising and experimenting.
