    Mounting Hyper Quick Release

    Using 4xM2.5 to mount the top part onto the frame or damping isolator.

    Pay attention to the arrow on the hyper quick release which indicates the home position or forward position of the gimbal.


    Connect the UBEC cable to the Hyper QR.



    STEP 1: The marks on the top part and bottom part must be aligned. The mark on the ring should be aligned with the unlocked icon as shown in the first picture.

    STEP 2: Keep everything aligned and attach the bottom part to the top part.

    STEP 3: Rotate the ring clockwise until the mark on the ring aligned with the locked icon.


    STEP 1: Rotate the ring counterclockwise.

    STEP 2: When the mark on the ring aligned with the unlock icon, the PIXY U can be detached from the top part of the Hyper Quick Release.

  • 07. Powering Up The PIXY U

    After connecting to the power supply, the gimbal will perform a series of alignments, self tests, which last about 2 seconds and the status of the gimbal will be indicated by the Status LED color. During this time, don’t touch the gimbal or camera.

    If there is a remote-control signal, changing modes or turning motors on/off by other methods will not take effect because the remote-control signal has the highest priority and will override the command.

    Step 1

    Make sure the Hyper Quick Release is mounted to the drone and its power port is already connected to the power supply correctly. Next, let’s mount the gimbal to the Hyper Quick Release, it will be automatically powered up.

    Step 2
    Wait about 2 seconds, do not touch the gimbal or camera.
    Step 3
    If the status LED is blinking green, the gimbal is ready for use.
    If the status LED is solid red, something is wrong with the gimbal and motors can not start. Connect to the software/apps to check the details of the error message.
    Read “LED STATUS INDICATOR” in next section for more information.

  • 09. Operation Modes

    LOCK MODE: is a stabilization mode where the camera maintains orientation independently of the rest of the gimbal and the orientation can be changed by an external control signal from remote control.

    FOLLOW MODE: in this mode, the camera will mimic the operator’s movement and allows one person to control camera tilt and pan without using an external device like a remote control.

    PIXY U Supports


    DUAL OPERATOR: a second operator can use a Remote Controller (SBUS, SPEKTRUM, PPM) to control gimbal’s movement.

  • 10. Working Operation

    PIXY U has 2 working operations: Normal and Inverted.

    After powering up the gimbal , it will automatically detect if the gimbal is in inverted operation or normal operation based on pan motor position.
    During working, switching to other working operation made easy by changing pan motor position, the gimbal will automatically detect new type of working operation.

    Swithing Between Modes

    Using mode channel on remote control

    Midle Lock mode
    Motors ON
    Low Motors OFF

    Using software

    If there is a remote control signal, changing modes or turning motors on/off by other methods such as using the function button or software will not take effect because the remote control signal has the highest priority and override the command.
