Read what Weads put up:
If stuck in a gentle left pedal turn in the hover:
a. roll off a little throttle. Turn will initially speed up and acft wants to sink - hold off the ground with lever. More torque but lower TR RPM, turn will slow down, maybe even stop.
b. If still turning, repeat.
c. when turn stops, allow bird to sink slowly to ground.
As Helmet Fire said in the archive, it is aircraft specific. Works on some. Roof-mounted throttles are a bit trickier to make it work if you don't have anybody up front with you.
