You wrote pretty much the same as Jim, but you obviously didn't read my response to his email, where I tried to explain why he (and now you) do not explain my problem. You both seem to have decided that I am yet another victim of the viewpoint illusion, something that I do well understand and did so before. I *did* align YASim's and the bo's origin, and I *did* adjust the view point. It doesn't help, because the bo is *really* *yawing* around the nose. (It isn't pitching around the nose, only yawing/turning!) How could my method create the described illusion? I'm looking at the bo from a few meters above. The bo stands on the ground with it's nose over an easily spottable point (e.g. a taxiway corner). Then I increase the collective (without lifting off), and turn the bo to the left. And the bo turns around the nose. There's no room for an illusion here. The distance from nose to ground is much too small. Try yourself: the attached patch aligns the 3d model correctly with YASim (which isn't the case now!), and sets the viewpoint to the CG. m. PS: I may still have missed something, but not what you and Jim think. :-(
