Btw, a good way to land, if you are in a situation where you need to go down
(safely) asap is to make a hard right-hand turn and put the nose up slightly.
That does two things: 1) it kills your speed quickly and 2) as your
speed drops to the area when the shaking starts, the right-hand turn eliminates
the need for left rudder.
Also, play with the collective right and you can drop quite a bit of altitude too.
If done correctly, you should be almost hovering stationary.
