Simply said, no, I hadn't even thought about it. Used spoilers on gliders to kill lift, wouldn't that be the same though? Would it slow the plane more in the 'up' position, and/or would it steepen the approach? Do they have a different effect on aileron function when in that mode? Since your familiar with them, I'm curious as to your observations. Seems like it would just as easy to program in. I've got the horns set a couple of notches forward for differential- would I change that?
