Hi Royden,

The strap pack on the OH-6 consists of 16, .009 inch stainless steel laminae. Each is coated with a teflon paint which aids in their movement while flapping and feathering. The only hinge is the lead/lag hinge located at the junction of the straps and the rotor blade. Covering the straps are cuffs where the friction damper and pitch horn are mounted. The cuff attaches to the l/l hinge and goes back to the hub where it forms a flange. The flange rides on three metal protrusions at 3, 6, and 9 o'clock to the flange. The 3 and 9 o'clock protrusions are to insure that all blades flap at the place and angle. The 6o'clock one is a droop stop.

Royden, I think that's pretty much it. Please remember that was 39 years ago since I flew the Loach.
