I have a Limbo Dancer that has plenty of power for 3D as well as plenty of throw in the control surfaces. However, when I position the airplane in torque roll/hover position, the rudder has apparently very little authority, even though it has plenty of travel (50 or 60 degrees each side) and is apparently large enough to kick the tail around. Whenever it starts to fall of a hover, I kick in some rudder and it simply doesnt seem to make much difference. BTW, I am using high torque servos on rud. and ele., so, lack of torque is not an issue. It feels to me that the prop wash doesnt reach the rudder as the rudder may be too high so it isnt in the path of the wash. does it make any sence?
I have seen several pics of people hovering their Magic, which to me, looks a lot like a limbo dancer. In fact, I wouldnt be able to tell the difference between them.
Why is that happening?

Thanks
