RE: how do you hover?
How to hover?
Increase the throttle until the model lifts off the ground. Modulate the throttle so that the heli maintains a steady altitude. At the same time, modulate the rudder so that the model maintains a steady heading. At the same time, modulate the cyclic controls so that the model maintains a steady position.
Or are you asking how to develop your skills so that you can do all of this successfully? Take a read through [link=http://www.dream-models.com/eco/flying-index.html]RADD'S SCHOOL OF ROTARY FLIGHT?[/link]
