Infinifly is a patent-pending technology developed by Hoverfly Technologies for long duration flight of multirotor aircraft. Infinifly consists of a ground power supply and automatic spooling system. A nanowire tether supplies power to an aircraft as far away as 400ft (determined by the spooling system). A 12VDC or 120VAC power source is all that is needed to allow multirotor flight for several days. The Infinifly system is designed to operate flawlessly with the Hoverfly Venu for live event coverage and long duration surveillance operations.
