The Futaba CGY755 is an advanced course-keeping and speed control gyro designed for high-performance model aircraft. It offers similar functionality to the CGY760, with the main difference being the absence of an integrated receiver in the CGY755.
Key Features
Gyro Section:
- PID Control: Utilizes a PID control algorithm proven on the CGY750, ensuring precise and stable control.
- Multi-Directional Mounting: Flexible mounting options to accommodate various model configurations.
Anticouple:
- Servo Compatibility: Supports both digital (1520uSec / 760uSec) and analog (1520uSec) servos.
- Adjustment Methods: Offers two types of setting methods—3D and Sports—along with some pre-set programs for easy configuration.
Lateral and Longitudinal Cyclic:
- Adjustment Methods: Includes two types of adjustment methods—F3C (fixed pitch) and 3D (variable pitch).
- Swashplate Support: Compatible with swashplate types H3-90, H3-120, H3-140, H4-00, and H4-45.
- Servo Support: Digital (1520uSec / 760uSec) and analog (1520uSec) servo motors available. (760uSec mode is planned for future updates.)
Speed Controller:
- PID Control Loop: Advanced PID control loop for precise head speed regulation.
- Head Speed Range: Usable for head speeds from 700 RPM to 4000 RPM.
- Control Modes: Selectable governor mode or revolution limiting mode.
