That's a condition I haven't tried...YET! I do have upline and downline snap conditions that are very similar to what you described, but they are dictated by either low or high throttle positions. They've been working well for me, but I may play around this season with the surface deflection setup you described.
I agree - that's the reason for the way I set it up!!I have seen SOOOOO many zeros because of wrong switch settings...
Some pilots are flipping switches so much its ridiculous. Thats just one more thing to mess up, unnecessary workload.
