701 Gyro & Gov w/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.

Gyro/Governor Features

• Small and lightweight — only 1.7 in. x 1.2 in., and weighs less than 1/2 ounce*.
• S.Bus capable with a single cable connection to the receiver.
• Free firmware and software, using the CIU-2 PC Interface (sold separately).
• Easy for anyone to program. Features both Basic and Expert menus.
• Organic Light Emitting Display (OLED) for easy viewing indoors or out.
• Works with analog or digital servos.

Gyro Features

• Utilizes MEMS (Micro Electro Mechanical System) technology:
• Ultra high-speed processing.
• Advanced PID control algorithm.
• Smooth, consistent pirouette rate and yaw control.
• Patented, internal “Feed Forward” mixing through S.Bus means no latency and no tail offset (available in S.Bus mode only).
• 3D/F3C mode-selectable.
• Sensor features an aluminum alloy case and 3-color mode indicator LED.

Governor Features

• RPM range of 1000-3000.
• Mode selectable for governor or rev limiter.
• Clutch-mounted sensor or optional back plate mount for O.S.® .91, .55 and .50 engines.
