Hey Todd - what rudder servos are you using, how many cells in your battery, and are you using a regulator (if so, what voltage).

David Reid, Vernon, and myself all had this full-deflection problem happen with 3421 servos and an unregulated 5-cell pack. Installing a regulator seemed to cure the problem, and then shortly after that BVM started recommending a different rudder servo - perhaps partly because of the above issues, and partly because BVM rep Harley Condra managed to melt his servos.

BTW, I have the 450, not the 460 - not sure what DavidR et al had.

You might also want to look at what gain you are using. Following our full-deflection issues (discussed here at great length on at least two different threads), a lot of people were recommending backing away from the very high percentage gains that were common at the time.
