I remember the Bell 47 had a lot of play on the servo input link (sloppy link) and as a tech, I even remember rigging them. As "You have" flying ballast I even recall that there was a fair bit of play in the cyclic too.
But for the life of me, I can't remember the jack schematic diagram... Anyone got one to hand? I have been trying to explain it to some youngsters who work with and for me and they can't understand a.: why and b.: how.
Was this a typically Bell 47 Sioux thing, or did other Bells use this slotted input link too? Hueys, Jet Rangers...
Thanks
