Gimbal Description
To avoid motor damage, ensure there is nothing blocking the rotation of the servo drive modules.
Clear obstacles or immediately cut off the power if any blockage occurs.
The servo drive modules have two motor command input ports and one private encoder port.
The HDMI-HD/AV module converts HDMI to HD (or AV) using a cable connected to the camera HDMI
port; it also transforms the TX signal into a shutter control signal by using a shutter control cable.
The camera shutter control cable is removable. Unplug it if this functionality is not needed.

4. Mount the gimbal onto the landing gear with the mounting brackets. Tighten the screws and use thread lock.
Ensure the lens is pointing in the same direction as the aircraft nose.
Ensure the top and bottom plates of the damping unit stay parallel when mounting. This prevents
stretching and distortion.
Maintain good overall balance when mounting in order to ensure the center of gravity is balanced
on each of the three axis lines.
The gimbal’s center of gravity has been set by the factory. The center of gravity directly determines
the gimbal’s overall performance. Do not adjust the gimbal’s center of gravity yourself.
The gimbal is highly precise and depends on this precision for optimal performance. Do not remove
any screws on the gimbal, as this may result in poor performance or damage to the gimbal.
Do not unplug any cables attached to the gimbal ports or change the mechanical structure.
Make sure the wiring is correct, otherwise the gimbal may behave abnormally.

should be in the position illustrated above.
7. The gimbal will then go into a second stage of initialization. At this time, each axis will rotate very slowly.
8. Once each axis stops moving, the gimbal is fully initialized and ready to use.
9. Toggle the assigned Working Modes switch on your TX and make sure it is working properly.
10. Switch the Working Modes to Non orientation-locked, FPV Mode (Reset), and Orientation-locked Mode
respectively. Then push the controller sticks lightly in the Roll, Tilt and Pan directions to check that the
gimbal moves in the corresponding directions. If not, see Working Mode/AUX2 Switch Setup to correct
your settings.
Appendix
Attention
For safety reasons, please pay careful attention to all of the following items:
1. To avoid motor damage, ensure nothing blocks the servo drive module’s total range of movement.
2. Before powering on, spin the gimbal through its complete rotation by hand on each axis to ensure nothing
is blocking the mechanical movement of the gimbal.
3. Be sure to mount the side of servo drive module 1 with the ports facing towards the aircraft tail.
4. The gimbal’s center of gravity has been preset. The gimbal balance is directly related to its performance.
Please do not adjust the gimbal’s center of gravity by yourself.
5. The gimbal is a sophisticated device. Do not remove any screws from the gimbal. Doing so may result in
poor performance or even damage.
6. Do not unplug any cables attached to the gimbal ports or change the mechanical structure.
7. Make sure all wiring is correct, otherwise the gimbal may not operate correctly or efficiently.
8. Make sure to connect the wireless video transmission module to the GCU prior to powering on the system.
9. We recommend use of the included AV video power cable, if needed.
10. Be sure to solder the AV video power cable to the wireless video transmission module correctly. Ensure
the cables are insulated and protected to prevent any type of short circuit.
11. Pay close attention to the voltage of S800 EVO/S1000 and be sure it is within the defined limits (6S) when
using one battery for both the S800 EVO/S1000 and as a power supply for the gimbal.
12. Never touch the contact points of a power cable to the gimbal; this may lead to a short circuit of the
gimbal, resulting in complete failure.
13. Before powering on, adjust the roll axis of the gimbal to be level.
