Palm-sized and micro helicopters can be flown indoors or out in calm weather or still air. Larger models that have bulk and power resist being swept away. Use common sense the model may be lost if flown in too breezy conditions. Most models are virtually ready to fly and complete with a good quality radio control unit, batteries and chargers, providing a brilliant way to get acclimatised to RC helicopter control.
Hover and train with low level lift off until landings are achievable. All models require careful flight training, manuals should be read and the basics of control mastered before extended flight is attempted!
