Nov.17, 2000DearI have not encountered this particular problem before so hopefully other readers can help out as well. On previous applications where I have had a problem with loose keys I have either peened the key slightly to fatten it and thus hold it in the slot or used blue (not red) locktite to hold it in place. The blue is a little less permanent than the red. The fact that the key is epoxied in place does not stop it from doing its job of sheering under extreme stress. Also without seeing it I can’t be sure about this, but check your sprocket - is there a missing set screw or collar?My autopilot is an Autohelm 6000 so I don’t know if my default settings would correlate to what you need but here they are:Rudder gain (level)5Rate gain (level)7Rudder angle limit (degrees)30Turn rate limit(degrees/second)20Cruise speed (knots)8Off course alarm (degrees)20Trim level1Auto AdaptoffIf this doesn't help you should know that Autopilot is now owned by Raytheon. The only person I deal with there is Jim Ogles at the electronics product repair center in Manchester New Hampshire. Jim was excellent to deal with but the rest of them I spoke to would be challenged to play “Find Your foot”. Phone: 603-647-7530, Fax: 603-634-4855.
