Thanks, Nick. Wasn't sure if S-76 had flapping hinges - so it does not have such a high offset as i thought. I imagine that hingeless and bearingless designs would need to use flap/pitch flexure in the blade itself (like a fixed wing). The S-300 rotor hub, just above the Sikorsky link, shows trailing pitch links - i didn't realise that trailing designs existed.
Must admit, to understanding Lu's point about the D3 in the R22 (rest his soul). I don't claim to have anything like the experience i would like, and to me it flies fine - as long as cyclic inputs are restricted in reduced g auto entry. However, I can see that if a pilot got himself disoriented when cloud crept up then having the rotor optimised for 1g coning could be problematic. This could probably be said of many designs.
