Heading-Hold Gyro & Governor

Sophisticated simplicity.
Beginner-friendly – competition-ready.

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.

*Also available in separate gyro or governor units.

“The Futaba GY701 rocks! Like the GY520, it offers superior gyro performance, with an easy-to-use programming interface featuring Basic and Expert modes. Piro rate consistency is unmatched. The governor is just as phenomenal, reacting to tail rotor demands even before the engine does. The GY701's compact size, user-friendly interface and S.Bus support result in a winning combination that's tough to beat!”

– Ray and Kyle Stacy, Team Futaba Members
