Hey guys, I want to use the snap roll button (also upper left trainer button) to activate a tank drop servo. So far, I haven't figured out how to do that. I seem to remember someone used it for a tank drop some time back. Does anyone remember, or know how to program the snap roll button to only activate one servo to drop a tank, instead of actuating the ailerons/elevator for snaps?

Any advice would be very helpful.

Thanks, Les Morrow
