The servo type parameters within the CGY750 must match the type of servo you are using. In- correct setting may damage the CGY750 or the servos, possibly resulting in a loss of control dur- ing flight.

Do not drop the CGY750 sensor onto a hard surface or subject the CGY750 sensor to a strong shock as this may damage the sensor.

RECAUTIONS transmitter, always set the throttle servo maxi- mum operating point to less than the point at which the governor is activated. If this is not done the governor may activate while in condition hold. While preparing for flight or starting the engine always ensure the throttle remains below the gov- ernor activation point and do not select any flight modes that may activate the governor.

The gyro operation is disabled within sev- eral of the settings menus to help with setup tasks. Always check the operation of the CGY750, verify that the controls are operating the correct direction and ensure the gyros are correcting in the proper direction for all axis before attempting to fly the model.

The CGY750 should compensate by adding clockwise rotation pitch to the tail rotor blades. If the CGY750 compen- sates by adding counter-clockwise rotation pitch to the tail rotor blades, then it will be necessary to reverse the Compensation Direction setting by pressing the [+] or [-] data key.

To obtain the best performance it is recommended to set the limit in the CGY750 the servo arm length to set the mechanical endpoints. After that has been completed use the servo limit parameter to make small adjust- ments that could not be made mechanically.

(2) Gyro direction [default: Normal] This parameter controls which direction the CGY750 (pitch axis) will compensate when the helicopter pitches forward or backward. Pick the helicopter up and rotate the nose of the helicop- ter downward. The CGY750 should compensate by adding aft cyclic to the swash plate.

The available presets are 450-550, The size profiles change many of the options within the CGY750 to tailor the gyro towards a certain helicopter size and the way that it reacts in flight. When using this option the CGY750 will be adjusted to provide a consistent feel for various helicopter sizes.

(5) Flight mode presets [default: 3] The flight mode presets are used to control the overall feel and aggressiveness of the CGY750 in flight. The adjustment range is 1 through 5. Flight mode 1 is the least aggressive and is intended for beginners, sport, scale and even pilots who are not very aggressive.
This setting is used to set the operational direc- tion for the Aileron CCPM servo. The easiest way to set up the CGY750 is to observe which direction each servo needs to move when the collective stick is moved towards positive col- lective pitch.

ENSOR NSTALLATION Important: The CGY750 gyro sensor must be mounted so that the roll and pitch sensing axis are in alignment with the helicopter. Any misalign- ments over 1/2 of a degree will cause a loss in performance. Please take extra care in this step to ensure the optimum flight performance.
Throughout extensive testing it has been found that the CGY750 gyro sensor performs best when the sensor is mounted rigidly to the airframe. This is mainly...

Vibrations contribute to this ground resonance. Verify that everything on your model is balanced correctly. * When the CGY750 is used with a ESC or BEC and a power switch is not used there is a possibility that the intermittent connection as you connect the flight battery may cause the CGY750 initialization to fail.
