"Ricardo, Thank you for the response. As for the Failsafe options, I would like CH-5 to operate the release and then have the plane RTL. It would seem that I can only enable or disable the throttle channel for Failsafe, which I don't want to do.…"

"Currently (until the new version comes out) you have to put the DO-JUMP command between 2 waypoints, the second waypoint is just a dummy and won't be flown to but for some reason it needs to be there otherwise the DO_JUMP won't be executed."
