And it's easy to program: Basic and Expert Menus are included, so that heli pilots at any level can enjoy latency-free performance and virtually instantaneous set-ups. An Organic Light-Emitting Display (OLED) allows clear viewing indoors or out. Together with its 1,000-3,000 rpm governor, the GY701 is a system that's ideal for even the most extreme helicopter competitions!
