I've been PM'ed a couple times on rudder throws, which are not specified in the Skymaster instructions.

I have used 3/8" each way on high rate (100%), with 75% at mid rate and 60% on low rate. We test flew at mid-rates and these throws seem to work well - Buck Garza and other F-18 drivers have cautioned against using too much rudder in flight as they are very effective and can cause the Bug to depart controlled flight quickly if "abused" at both high and low speeds.

Have fun!
