GCU Connection

Skip this chapter if you have the Phantom 2 version of the H3-3D gimbal, as it does not

come with a GCU.

The GCU must be connected to the flight control system before it is powered on.

Be sure to mount the camera onto the gimbal before powering on the aircraft and the

gimbal. Otherwise the servos may be damaged due to an incorrect center of gravity.

Re-calibrate the remote control whenever the NAZA-M firmware is upgraded.

Ensure all connections are correct, otherwise damage to the gimbal or the flight control

system may occur.
