RE: Control Surfaces at Hover
All my 3D planes are set up 0-0-0 and I've even gone away from using right-thrust on the motor now (that's what the rudder is for :-)
In a plane that you intend to 3D, anything other than 0-0-0 is just something you'll have to fight on the sticks anyway because when you're hucking hard you'll spend as much time inverted as upright and more time flying on the prop than on the wing.
