Bell 212 Collective rigging question
This is a question for my fellow Engineers.
I am bored at work today and was re-reading the maintenance manual (yes I am that bored) and It has always bothered me that I cannot come up with a good reason for why the manual states in paragraph 67-2 step 5 to shorten the servo input rod 3-5 turns for the collective servo while for both cyclic servos you are to shorten the input rod exactly 3 turns.
Obiously this is to protect the servos from being bottomed out and damaged at their extremes of travel but why is there a range allowed for the collective servo and a specific number for the cyclic servos?
I have had conversations with co-workers about this and haven't really been able to come up with a logical explanation, anyone on here have a fancy reason I can impress people with?
