Getting Started

  • 01. Introduction

    The new T3 features HDMI Quick Release as well as new I/O design and the ability to start up in 2 seconds. Moreover thanks to the increase in regulated voltage, motor power is also increased up to 20%

  • 02. Features
    HDMI Hyper Quick Release
    New mechanical and electrical integration quick release features floating connectors that allow to transmit high speed HDMI video signal while still maintain reliability after many mating cycles.
    Say goodbye to complex setups and time consuming process. The T3 provides an easy one step plug and play installation that takes only 5 seconds to complete.
    Intuitive hardware interface including a variety of ports has relocated on QR to quickly interface with multiple devices such as 3rd party flight controller, remote control, auxiliary I/O and power your ideal system of cameras/accessories.
    Heated & Temperature Controlled IMU
    Heated and temperature controlled IMU sensor with advanced 6-point calibration allows reliable performance even in extreme weather. Temperature is maintained within 0.2 degrees Celsius accuracy.
    High Performance Gimbal Controller
    gMotion Controller, designed and made by Gremsy based on a 32 bit high performance ARM microprocessor providing fast response and accurate calculation. Sensor data and motors correction are updated as fast as 2000 times per second to enable incredibly smooth footage.
    No exterior wires, more solid. This clean design helps the T3 overcome wind resistance with ease to bring out the best video quality while staying agile.
    The T3 has a lot of nice features that enable users to apply it not only for aerial inspection and mapping but also for high end aerial cinematography.

    Mounting Hyper Quick Release

    Using 32mm square M3 pattern to mount the top part onto the frame or damping isolator.


    STEP 1: The marks on the top part and bottom part must be aligned. The button 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 hearing a snap, the button should be automatically popped out and aligned with a locked icon.


    STEP 1: Press and hold the button.

    STEP 2: Rotate the ring counterclockwise.

    STEP 3: When the button aligns the unlock icon, the T3 can be detached from the top part of Hyper Quick Release.

  • 08. Powering Up The Gremsy T3

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

    Always start the gimbal with a balanced camera set up otherwise after initialization the controller will return an error followed by a red color indicator.

    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. By default, the gimbal is in Follow mode if the motors are turned ON by the Function Button.
    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 details of the error message.
    Read “LED STATUS INDICATOR” in next section for more information.

  • 10. 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.

    GREMSY T3 Supports


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

  • 11. Working Operation

    GREMSY T3 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 another working operation made easy by changing pan motor position, the gimbal will automatically detect new types of working operation.
  • 12. Swithing Between Modes

    Using function button

    Once time Turn motors ON
    2 times Lock mode
    3 times Follow mode
    Hold 3 seconds Turn motor OFF

    Using mode channel on remote control

    High Follow mode
    Motors ON
    Midle Lock mode
    Motors ON
    Low Motors OFF

    Using software/application

    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.
  • 13. Installing Software/ App

    Mobile apps are available in App Store and Google Play

    App name: gTune

    Searching: “gremsy gtune”


    Desktop software

    Download at: -> Support -> Product Support -> GREMSY T3

  • 14. Using USB/ Bluetooth Connection
    To configure and monitor data of Gremsy software/app either USB/Wi-fi connection is required.
    Make sure the Silab USB driver is already installed. The driver can be found at: -> Support -> Product Support -> GREMSY T3
    • 1 - Power ON the GREMSY T3.
    • 2 - Connect USB cable from gimbal controller to Mac/PC.
    • 3 - Run the gTuneDesktop software.
    • 4 - On Connection Tab, select the Serial option.
    • 5 - Select the correct COM port in the list.
    • 6 - Click on the “Connect” button.
    • 1 - Enable bluetooth adapter of mobile devices
      On Android: the OS will ask for Location Data permission for BLE scanning feature (updated by Google since Android 6.0)
      On iOS: the OS will sometimes have issues with its Bluetooth adapter. Users should check the device’s quick settings and general settings to enable the adapter and the Bluetooth icon should appear on the device’s status bar.
    • 2 - Turn ON the gimbal and run the app.
      After switching to Bluetooth, the app will begin scanning for Gremsy Bluetooth integrated gimbals.
      If only one gimbal is found, it will be connected automatically.
      If more than one gimbal is found, a list of gimbals will be shown to allow the user to select the desired one.
      If no gimbal is found, an error will be shown.
