Setup
1. Install Landing Gear
Attach the four pieces of landing gear to the underside of the drone. Secure each piece with the provided screws using the small screwdriver.
2. Attach Propeller Guards
For beginner pilots, it is highly recommended to install the propeller guards to protect the blades from damage during initial flights. Gently snap each guard onto the motor arms, ensuring they are securely fastened.

4. Charge the Drone Battery
Connect the drone's battery to the USB charging cable. Plug the USB cable into a compatible USB power source (e.g., computer, USB wall adapter). The indicator light on the charger will typically show red for charging and turn off or green when fully charged. Ensure the battery is fully charged before first use for optimal flight performance.

6. Install Phone Holder (Optional)
If you plan to use the FPV feature, attach the phone holder to the top of the remote controller. Secure your smartphone in the holder, ensuring it is stable and does not obstruct any controls.
Flight Operation
1. Power On and Pairing
Place the drone on a flat, level surface. Turn on the drone's power switch. The indicator lights on the drone will flash. Turn on the remote controller. Push the left joystick (throttle) all the way up, then all the way down. The remote will emit a beep, and the drone's lights will become solid, indicating successful pairing.

2. App Connection for FPV
Download the "MJX FPV" app from your smartphone's app store (iOS/Android). Turn on the drone. On your phone, connect to the drone's Wi-Fi network (e.g., "MJX_H_C4005_XXXX"). Open the MJX FPV app and enter the monitor interface to view the live video feed from the drone's camera.

3. Basic Flight Controls
Take-off: Gently push the left joystick (throttle) up to lift off. To land, slowly pull the left joystick down.
Directional Control: Use the right joystick to move the drone forward, backward, left, and right.
Headless Mode: Activate Headless Mode by pressing the dedicated button on the remote. In this mode, the drone's forward direction aligns with the remote controller's forward direction, simplifying orientation. Press again to exit Headless Mode.

4. 3D Flips and Rolls
To perform a 3D flip, press the 3D roll button on the remote, then quickly push the right joystick in any desired direction (forward, backward, left, or right). The drone will execute a 360-degree flip in that direction.
