NTRODUCTION
Futaba CGY760R/CGY755 is gyro, 3-axis Stabilization System combining AVCS
gyro and head speed governor in one box designed for flybarless helicopters. Its cut-
ting 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 performance.
CGY760R has a receiver function.
CGY755 has no receiver function.
This manual is for both CGY760R with receiver
function and CGY755 without receiver function.
If your gyro is CGY755, ignore the description of the receiver
function in this dotted box.

  • Page 15 MACHINE MAINTENANCE: WARNING Even though the CGY760R/CGY755 is a high performance gyro and governor, it will be necessary to ensure that the helicopter mechanics are also in optimum operating condition. Please use the guidelines below and address all issues before installing and flying the CGY.

  • Page 16: Mounting / Part Name / Connecting

    *The CGY760R/CGY755 should be mounted on a rigid platform, at least 6 in. [152 mm] away from a Nitro Engine. It is not necessary to mount the gyro near the main shaft of the model but it is very important that the mounting area chosen is rigid.

  • Page 17: Mounting The Cgy(Cgy760R/Cgy755)

    Mounting The CGY The CGY760R/CGY755 can be mounted in the orientation shown below unless it is installed so that the roll and pitch detection axis are aligned with the model. However, if there is a deviation of , equal to, or greater than 1/2 degrees, performance will degrade. In this step, please pay special attention to ensure optimum flight performance.

  • Page 92: S.bus Servo Setting Screen

    S.BUS SERVO SETTING Screen An S.BUS servo can memorize the channel and various settings you input. Servo setting can be performed on the GPB-1 screen by wiring the servo as shown in the figure. *With some S.BUS(2) servos, there are some functions which cannot be used. If a function cannot be used, the display screen will change.
