Rotorbee - perhaps things are getting confused here - I think your reference to just push the cyclic forward is about a situation in a hover taxi with some MR/TR vortex interaction giving some undemanded yaw and NOT as a cure to the wildly spinning Cabri - am I right?
We used to demonstrate MR vortex entering the TR on the Wessex, usually at high AUM in a hover taxi with the wind from the 10' o'clock position (anti-clockwise rotor) - it caused vibration and some minor heading variations but nothing more. Changing the speed or the wind angle removed it entirely.
