thank's for the answers guys, I guess the aerodynamical advantages of a tailrotor 'feeding' on downwash isn't big enough for Robinson to re-design the R22 to the more efficient, not that it needs a more efficient TR anyway, maybe this effect is more noticeable/needed on bigger choppers. The Hughes 300 spins the 'wrong' way around (like the R22) aswell if I'm not mistaken?
Cheers
