Johnson, MD" : At altitude, I sometimes need to help the servos out with manual inputs for large/rapid course changes due to the stiffness of the control boots around the aileron axis. At low altitudes, the wandering off heading I noticed occurred with the NAV function only when the box was slaved to my GPS. STEC told me that anytime flying slaved to a GPS, one should have both NAV/APR buttons active, as the GPS tone was too pure for the NAV button to track alone. Seems to work well--not wandering off since. Doug Johnson 654DM
