OK ChrisC . . . I'll be careful with the settings. I did finish the installation today, but it's way too windy to try it out. Anyway, I have the sensitivity wired to work with the proportional knob. The only way the knob works is to have the sensitivity on the co-pilot full clockwise (on). After reading your post . . . I'll turn it down to start with.

Thanks,

c130nut . . . all I can tell you is most everyone that uses the co-pilot are very pleased. So for $100.00 it is worth a try. If you do a search "FMA Co-pilot" on RC Universe you'll get plenty to read. Good luck with your C130!
