That's scary to look at, but I do not think that failure has anything to do with the control system being mis-rigged.
Shortening the input rod end is without a doubt to prevent servo and airframe damage.
If the input rod was too long AND the servo's bottom rod end bearing was not adjusted to the proper length to fit exactly in the bottom fitting the servo would be exerting force against the airframe between its upper mounting ladder beam and the lower fitting when at its fully extended position. Or at least that is my understanding.
My question is as to why the cyclic system gives an exact number of turns to shorten its servos' input tubes while the collective allows you a range of adjustment (which isn't really useful for any other part of the rigging procedure.)
It's not really important I guess, I just hate reading the manual and doing things "because that's what the book says" and not for a logical reason that I can explain to myself.
