Believe me ... I truly know how minor mine was, I watched a friend's X-cell 60 pro graphite roll in from 30ft, after it hit, the throttle jammed and it proceeded to ad insult to injury by beating itself to death. All because of a PCM lockout. His ship looked pretty bad, was a little spendy to fix. Now he's spooked about flying it. We still haven't figured out why it locked up.
