Something everybody tends to forget or have never run into is LTE (loss of tail rotor effectiveness) at least in the R 22 when in a hover. Try to avoid the wind off the nose from the 10 to 11 clock angle when in a high hover so the main rotor vortices stay out of the tail rotor. If it shoud happen the tail can snap around extremely fast to the right and scare the crap out of both of you.
