  2. For charging, connect the USB charging cable to the drone battery and a USB power source (e.g., computer USB port, USB wall adapter). The charging indicator light will show charging status.
  3. Install 3 x AAA batteries (not included) into the remote controller, observing correct polarity.

3. Propeller Check

Ensure all propellers are securely attached and free from damage. Replace any damaged propellers with the provided spares using the screwdriver.

4. App Download and Connection

Operating Instructions

1. Pairing the Drone and Controller

  1. Place the drone on a flat, level surface.
  2. Turn on the drone. The indicator lights will flash.
  3. Turn on the remote controller.
  4. Push the left joystick (throttle) all the way up, then all the way down. The drone lights will become solid, indicating successful pairing.

2. Take-off and Landing

3. Altitude Hold Mode

The X900 drone features Altitude Hold, allowing it to maintain a consistent height without continuous throttle input. Once the desired altitude is reached, release the throttle stick, and the drone will hover at that height, making it easier to control and capture stable footage.

4. Headless Mode

In Headless Mode, the drone's orientation is relative to the pilot, regardless of which way the drone's front is facing. This simplifies flight control, especially for beginners, as you don't need to worry about the drone's actual heading.

5. 3D Flips and Stunts

To perform a 360-degree flip, fly the drone to a sufficient height (at least 3 meters). Press the 3D flip button on the controller, then push the right joystick in the desired direction (forward, backward, left, or right). The drone will perform a flip in that direction.
