you know, i have to say this is a great question... i noticed that nowhere in my preflight do i check linkages and such for cyclic until im already @ RRPMs that would almost allow flight. i mean, we do a cakemixer check of them when we first get in but dont actually get down on the floor and look at the mechanical linkages that are held in with what looks to me like cotterpins. im talkin an s300cb, and when i move the pedals aft, so i can reach em, i make a point to at least LOOK at the control linkages and make sure something didnt flop out of the cupholder and get in there to limit movement.
