i just throw some expo (-30%futaba 8uaf) on the throttle so that you have more resolution in the hover range than normal. i use the 3 way switch for the spoil-off-flap setup.
i like "the crash switch" it can be very true, dual rates can screw me up so i stopped using them, but i have found that i have been reducing throws on my stuff to the point where they fly more consistent and still do flat spins and everything else, but i still love huge aileron thow all the time.
I'm still on the fence about whether expo is a bad thing or not, i reduced my expo then started adding back again because i found my flying to not be as smooth as i liked without using D/R, i found i was overcorrecting on hovers even with the smallest stick movements. I dont want to start a whole EXPO debate but what are your thoughts on this people??
