I just got a 9Z, so I'm going to try snap spoilerons this season. I tried to make them work on the 9C, but it's not capable. The "snap" part of the equation eliminates (at least for me) the need to hold a switch for a wall, parachute, or waterfall. You can program the radio to bring spoilers up or down to a certain position (and hold it there) given a certain elevator position. For example, at 75% elevator throw, spoilers come up to 50% and hold, regardless of how much the elevator goes up after 75%. At elevator throw 0% - 75%, spoilers stay down.

So, if you are in bind, and need to get out of a harrier, you know anything less than 75% elevator (for example) will bring the spoliers down.

For those of you interested, the 9C (with a 5 point curve) can snap the spoilers up, give a certain elevator position, but continue to rotate after they've snapped up. They will not hold in a give position. 9Z will hold them, or so I'm told.
