bruce,

Im not talking about all servos. The crash of my Mustang was due to IF burned of Rx. One of my servo was acting up, yes, but the cause of my plane's crash was IF not the servo. What I experienced couple of times during flying, that left aileron stopped responding, one of the senior flyer who is also commercial jet airliner pilot he flew it too, and told me the same thing, but somehow as it was flying and engine was running on and off it would respond and not, but he landed her safely and told me don't fly it until you resolve this glitch. When my plane crashed it took a left turn, it moved right aileron it didnt respond, as it took a deep nose left dive and crashed, finally I gave it to a friend of mine most senior flyer and electronics experts, he showed me it was burned. That would have been the major cause of crash not one servo. But one servo playing up may cause severe problems.
