Rotor stall
Teathering versus Star flex
My simulator is R44, so fully teathering and coning hinges.
But as per Shawns remarks (he referred to the 407 correction: MD520 if I recall correctly) and my personal remarks, I do not thing this makes a big difference before main rotor stall. The only possible problem with teathering is that when retreating blade stall sets in brutally, tail cone contact will be made easier than with the star flex or other more rigid systems.
