Futaba CGY755

Features of the Futaba CGY755 rc helicopter gyro:

It is successor of CGY750. The system combines the 3 axis heading hold gyro and the head speed governor. Functions and setting parameters basically follow CGY750 Ver.2.0.
Small and light weight, it has a luxurious appearance.
The wireless setting of some parameters is available through trainer function of the transmitter connected with GPB-1.
760 uSec swash servo (under development) will be available.

Gyro section:

Advanced and adaptive PID control loop which is proved by CGY750. Various mounting directions options.

Rudder (Yaw): Digital (1520uSec / 760uSec) and analog (1520uSec) servos are supported.
2 types of setting method, 3D and Sports.
Feedforward operation is implemented.

Aileron (Roll) - Elevator (Pitch): 2 types of setting method, F3C and 3D.

Supports H3-90 / H3-120 / H3-140 / H4-00 / H4-45 swashplate types.
Digital (1520uSec / 760uSec*) and analog (1520uSec) servo are supported. (* 760uSec mode is for the future.)

Head speed governor section:

Advanced and adaptive PID control loop which is proved by CGY750.
Capable of governing head speeds from 700 RPM to 4000 RPM.
Digital (1520uSec) and analog (1520uSec) servos are supported.
Governor or revolution limiter mode selectable.
Cutting edge control algorithm provides more consistent RPM governing.
Revolution sensor is compatible with the GV-1 and CGY750. The CGY760R also supports an optional revolution sensor.
RPM data can be send to the transmitter. (Telemetry function).
