4.4 Fungsi Khas
4.4.1 Altitude Hold

Rajah 4.4.1: Visual representation of the Altitude Hold feature, where the drone automatically maintains a set height, indicated by a lock icon.
The drone automatically maintains its altitude once the throttle stick is released to the center position. This allows for more stable flight and easier photo/video capture.

Rajah 4.4.3: Illustration of the One Key Return function, showing the drone automatically flying back towards the take-off point after a button press.
Press the One Key Return button. The drone will automatically fly back towards its take-off point. Ensure there are no obstacles in its return path. This function works best when the drone is within a reasonable range and has a clear signal.
4.4.4 3D Flip and Roll

Rajah 4.4.4: Dynamic image showing the drone executing a 360-degree 3D Flip and Roll maneuver in the sky.
To perform a 3D flip, fly the drone to a height of at least 3 meters (10 feet). Press the 3D Flip button (usually a dedicated button or a combination of stick presses). Then, quickly push the right control stick in the direction you want the drone to flip (forward, backward, left, or right). The drone will perform a 360-degree flip.
4.4.5 Gravity Control Mode (via App)

Rajah 4.4.5: Illustrates the Gravity Control Mode, where the drone's movement (turn left, turn right, forward, backward) is controlled by tilting the connected mobile device.
Within the MJX FPV app, you can activate Gravity Control Mode. This allows you to control the drone's movement by tilting your mobile device. Tilt forward to move forward, tilt backward to move backward, and tilt left/right to turn left/right. Ensure you are in a safe, open area when using this mode.
