Can a Slow-G hover?
No. Unlike a helicopter with a powered rotor, an autogyro depends on airflow over its rotors for lift and over its tail feathers for control. A Slow-G can fly with very little forward speed and will appear stationary in the slightest headwind, but it will not hover in the true sense of the word. It can descend vertically, but at zero airspeed its aerodynamic controls will have zero effectiveness, so you always want to carry at least some forward airspeed.
