The reason I said that it might be a servo is because I once had a  
servo take down the whole system.  I was doing a four point roll and  
the airplane never came out of the third point.  Everything seemed to  
work fine on the bench, but I discovered that, if I moved the aileron  
servo in small increments, it would get to a "bad" point and the  
whole system would freeze up and fail to function.  If I moved the  
servo off that "bad" point manually, the system worked fine.
