Hi KWard, be aware that the saitek throttle, most of the time, doesn't meet the 100% on/off mark.
In this case, in the SA-342 Gazelle helicopter that is, there is an issue with the autopilot.
I donn't know if there are more plane's/helicopters that have this problem.
But i saw the picture of you're saitek throttle and thought i warn you in advance.
