Well, terms used may be different but it sure shows up: for the BO 105 does the rotor turns anticlockwise when viewed from above?- if this is the case then it seems to be the similar phenomenon. I had considered the contributing factors in this phase of flight as the rigid rotors with low inertia blades at 2 'g' turns to the left.
It just two factors I could think of......
I may not go with the jack stall or servo transparency though.
Could I know the forums that this has been discussed?
