Matt,

I can't speak for AMT but I'll describe what I hope will happen with my experimentation with my AMT Mercury.....

Program in the radio a failsafe that is tied to the emergency shutdown switch. Failsafe over-ride to shut down the turbine after a predetermined time will only occur in the event of a failsafe. If no failsafe condition exists, the switch will work normally. (No delay.) This makes sense to me as all of the other channels work normally during non-failsafe periods and are over-ridden only when a failsafe conditon occurs and the failsafe is programed. Does this make sense to you???
