I have had a throttle servo die, engine come loose and another time the linkage had come off. All those times made much easier due to cutoff.
Geez Eagleburger
I hope they didn't happen all at once
Oh - I just realised - it was probably "that 4 lettered product" that shook it apart
I prefer to use cutoffs for safety. (I only use the smartfly one these days) The only time I have ever needed to use one was due to my own error in an assembly. Nowadays, I also leave the throttle return spring on the engine.
