You can get it forwards, sideways, backwards, whenever the airflow across the disc is about 12 kt.
The directional stability will become a problem when you get towards the limits of tail rotor authority, and it will want to weathercock into wind. Also when going backwards the horizontal stabiliser will cause you to tuck the cyclic back into your intestines, and again you will run out of cyclic authority and have a windscreen full of ground, somewhat scary.
