Another consideration is servo resolution. It's wise to always adjust your endpoint adjustments to the max (providing maximum servo rotation) and go back from there to even out throws if needed. Also (something I preach but don't practice yet) it would be wise to adjust your rates to be as high as possible. This adds even more servo travel. This allows you to use LONG horns on the surface but short arms on the servo, and provides the maximum amount of mechanical advantage.

Tom, what you mentioned in the above paragraph is what I am now experimenting with. I am now starting to reduce my servo arms length to increase my servo travel for the desired surface travel. Instead of setting up the plane with max surface travel initially, it seems like the smart thing to do is setup for moderate travel and slowly increase the travel until you have enough travel for your desired mode of flight. I am starting to think that I have too much travel in the surfaces for what I need, and I am wasting mechanical advantage, as well as servo resolution at the expense of high throw rates that I can't use.
