I haven't done much here the last few days, mostly due to weekend LIFE, guys, but I thought I toss in these little facts:
1) The Comanche hovered 6 degrees left wheel low because the TR (fan actually) was low and almost perfectly lined up with the CG. That was because we didn't want it higher - why add an intermediate GB and why should there be a large yaw to roll coupling in sideslips at high speed flight (where the TR yaw restoring force would roll the aircraft as well as put the nose back straight. - BTW, why does a high TR create MORE roll in forward flight, in spite of that same TR-MR height issue???) The design team agonized about this, and even contemplated tilting the crew seats in a hover to help "fix" the problem.
2) The Fantail demonstrator hovered at 5 degrees left wheel down, vice the S76B that it began life hovering at 3 degrees.
The items we are discussing are not theoretical, and Crab and I are not just supposing, these facts are part of what one does when one designs these things.
Until you guys understand wat a free body diagram is, it is not terribly useful to sketch, debate and sketch again, fun though it might be.
