I found that I didn't like the scheme Futaba uses for throttle cut for a variety of reasons. As a workaround, I set up a simple dual rate for the throttle channel which I assigned to a switch. When the switch is activated, the throw going towards low throttle is increased which kills the engine. I also included a warning sound in the form of a wave file so I'll know if I accidently activate it in flight. The nice part is that it won't kill the engine unless the throttle stick is already in its lowest position. Also, when turning the radio on, I get the warning tone I assigned if the switch is activated, but the radio will still transmit normally. Works good for me. Hope this helps!
