Futaba CGY770R is gyro, 3-axis Stabilization System combining AVCS gyro and head speed governor and receiver in one box designed
for flybarless helicopters. Its cutting edge MEMS (Micro Electro Mechanical System) sensor design, ultra high-speed processing speed,
and advanced PID control algorithm put it a league of it's own ahead of all ahead of all other heading hold gyros in size, weight and per-
formance.
• 3-Axis Gyro and Governor and Receiver in one box.
• High speed operation and extremely low latencies result in greater stability.
• Low profile, small size, and light weight.
• Easy set-up and tuning the gyro and governor program using the GPB-1.
• Settings divided into Basic and Expert menus. The basic setting is for initial set-
ting and Expert setting is for more advanced settings.
• Firmware can be updated from a Windows based personal computer when used with
the optional CIU-2 or CIU-3 interface.
• S.BUS 2 compatible.
• UR (ultra response) System compatible. When combined with the UR servo(for
helicopter), ultra-high-speed response is achieved.
*Car UR servos cannot be used.
• Gyro section
• Advanced and adaptive PID control loop is utilized.
• Simultaneous control of 3-axes (roll, pitch, yaw).
• Compatible with 1520 μs Analog, 1520 μs Digital, 760 μs Digital and UR
mode servos.
• Rudder (yaw) section:
• Capable of sensing angular velocity up to +/- 1,000 deg/sec.
• Feed Forward Option allows the CGY770R to consider other control functions
during operation. This results in more accurate corrections and precise opera-
tion.
• Cutting edge control algorithm provides a consistent pirouette rate, precise op-
eration, and smooth yaw control in any flight condition.
• Aileron, Elevator (roll, pitch) section:
• Developed specifically for flybarless helicopters.
• Supports H3-120, H3-140, H3-90, H4-00, and H4-45 swash plate types.
• Governor section
• Advanced and adaptive PID control loop is utilized.
• High speed operation and extremely low latencies provide a more consistent
and accurate operation.

FEATURES FEATURES
• Capable of governing head speeds from 700 rpm through 4,000 rpm
• Compatible with 1520 μs Analog and 1520 μs Digital throttle servo types.
• Feed Forward Option allows the CGY770R to consider other control functions
during operation. This results in precise governing of the head speed.
• Governor or Revolution Limiter mode selectable.
• Supports gear ratios from 1.00 through 50.00.
• Cutting edge control algorithm provides more consistent RPM governing.
• Revolution sensor is compatible with the GV-1. The CGY770R also supports
an optional back plate revolution sensor and brushless phase sensor.
• Receiver section
• Switch FASSTest - 2.4 GHz (18/12CH mode) system and T-FHSS - 2.4 GHz
system using the Gyro Program Box GPB-1 system.
• By S.BUS 2 system compatibility, it is possible to transmit the battery volt-
age information of the receiver and the optional sensor information con-
nected to the S.BUS 2 port of the receiver.
• Diversity antenna system.
• DUAL RX system.
• Other functions
• Maximum rpm memory.
• Cumulative engine operation timer.
• Integration function of engine operation time.
• Applicable systems
• Transmitter : Futaba FASSTest-2.4 GHz (18/12CH mode), T-FHSS Air-2.4 GHz
*Wireless tuning function is only supported by FASSTest.
*There are restrictions on wireless tuning depending on the item.
