Shel,

The UK needs that much dihedral to fly knife edge correctly. I think you will 
find that the model will tend to tuck down and roll in the opposite direction 
of applied rudder, in adverse roll and pitch couple. It will make the plane 
harder to fly in a neutrally balanced, Pattern like way. You can always mix 
in the correct elevator and aileron electronically, but why go through the 
trouble? I

In fact if you choose to make your change and do not mix in the correct 
mixes, landing would become more difficult everytime you correct the plane in 
yaw.
