GY701 Gyro + Governor +BLS251

The Futaba GY701 combines a gyro and governor in one unit, representing a quantum leap forward in technology*. Processing rates are incredible, resulting in response rates that are even more amazing. Basic and Expert menus make it easy for novices and pros to enjoy latency-free performance and virtually instantaneous set-ups. The GY701's OLED (Organic Light Emitting Display) is easy to read indoors or out. When combined with the Governor, you have a system that's optimized for even the most extreme helicopter competitions.
