Default RE: Control Throws for Pattern Flying?

I am a pattern flyer who likes to have a funfly to goof off with, and got a Reactor which I'm now putting together with a YS63. I want to do fun-type 3D, nothing outrageous, plus I'd like to see if I can set up the low rates to demonstrate/practice various pattern maneuvers as well. I'm setting up high rates at +/- 45 on rudder, 25 ailerons, 45 elevators, then low rates 30 rudder, 12 ailerons, +10 and -12 on elevators. These are initial settings, subject of course to changes as the model gets flown. The 45 degree throws on rudder and elevator high rates will be ample for any maneuver I expect to fly, and 25 on ailerons may be way too much for my kind of flying. The ailerons and elevators are way, way too big for normal pattern flying, so I will almost surely tone down the low-rate throws after I've made a few flights with it.

The important thing, as I see it, for a 3D/pattern hybrid, is to have full servo travel (maximum end-point adjust) at the high rates, so resolution is compromised no more than necessary on the low rates. This is mainly a matter of the relative moment arms on servos and control horns. Also ball links for linkages, to eliminate slop as much as possible.
