Hi,
just wondering re extending the RW shaft, I remember that over the years a few have gone down that path, and I also remember that some had issues with flying i.e. porpoising, at the time it was thought that the cowling of the turbine was the issue.
I simply am looking for results issues and benefits as I have a tentative plan to fit a gearbox with a tail rotor drive (not the RW one) along with a new tail rotor hub and I am thinking a good time to lift the rotor head another 6" or so., Also a new swash plate with a far greater range, (The swash plate in the attached is for a 3 bladed design, and the shown bell cranks were for a full set of push pull rods.)

I also wonder if raising the rotor head without raising the tail rotor might also have something to do with it.
Just thinking out loud, maybe someone with some first hand experience could offer their thoughts??
