RE: Control Surfaces at Hover
The hover is a "balancing" act and if you have to hold in a lot of elevator then you're not at the balance point.
With my GeeBee, Katana and Mojo, hovering is almost "hands off" when it's properly balanced in a hover.
You'll find that most planes won't torque on their own (ie: without using aileron) until they're really balanced in the hover that's because if they're either forward or back of balance they'll be moving slowly through the air and that stabilizes them from torquing.
Are you letting the engine torque the plane or are you using the ailerons? If the latter then you're not on the balance point and need to lean it back or forwards a little more so you can ease-of that constant elevator input.
When I'm hovering, most people comment that I'm hardly touching the sticks.
