As embarrassing as it is, I had the aileron servos reversed after swapping servos last night in my Midwest Cap. My pre-flight was half-@$$ and I only saw that the ailerons were moving. Took off and it only took a couple seconds to realize what I did, a full left roll with right stick.
Somehow I kept from crashing long enough 'til someone could go into the programming on my 9C and reverse two channels during my flight demo. It was real scary when only one servo was switched, no roll control at all. In the end I'm one lucky SOB. Should have had to bring it home in a bag. Probably all out of good luck after this one. I changed servos because one died in flight yesterday.
