As per #4 and #5 ...
Most important rest your forearm on your thigh if you can, and keep it there; hold the cyclic lightly between thumb and the first two or three fingers only. Concentrate on the horizon and as soon as the aircraft attitude changes adjust it back quickly to the hover attitude with small movements before the aircraft moves; there is usually quite an interval between the change in attitude and aircraft movement unless the attitude change is big. If it does move go back to the hover attitude first then make small cyclic changes in opposition to the direction of travel until stopped, then hover attitude again. It's easier to prevent losing the hover than regaining it! Glance closer to the aircraft only to judge height and movement over the ground. Prolonged hovering is not easy so don't try for too long, try to relax, especially that hand and arm! We all felt as though we were rolling about in a saucer when we first tried to hover.
