1. Balanced charging: Switch off the transmitter's power. Insert the USB port of the charger into the computer's USB port, and connect the other end of the charger to the drone's charging port. The drone's indicator light will be red while charging. It turns off when fully charged.
2. The battery can also be charged using a mobile charger or car-loaded power.
3. Full charging takes approximately 100 minutes. A fully charged battery provides around 8 minutes of flight time.

1. Fly the quadcopter in a spacious indoor area or an outdoor area free of obstacles, rain, snow, animals, and people. Avoid windy conditions outdoors.
2. Ensure all propellers are installed correctly for proper takeoff.
3. Make sure the remote control is assembled with new or fully charged AA batteries.
4. Ensure the drone's lithium battery is fully charged.

1. Turn on the remote control by short-pressing the power button. It will beep once, and the "STATUS" light will flash (Pic.1).
2. Check the lithium battery (3.7V 650mAh) and ensure it is inserted into the battery compartment of the drone (Pic.2).
3. Place the drone on a flat, level surface. Press down the drone's power button to turn it on (Pic.3). The drone's lights will begin blinking.
4. Quickly shift the throttle stick (left stick) up and down. If successful, the transmitter will beep, and the "STATUS", "SPEED2", "SPEED1", "ROLL", "NORMAL" LED lights on the remote control will turn on (Pic.5). The drone's LED lights will flash slowly (Pic.6).
5. The drone is now connected to the remote control and ready for takeoff. Press the "A Key Take Off" button to take off automatically (Pic.7).

The display shows various modes: State Display, Normal Mode Display, Speed Display, Headless Mode Display, and Tumbling Display.

• The drone is equipped with Altitude Hold Mode by default, maintaining a constant altitude during hovering.
• Pushing the left throttle stick up ascends the drone.
• Pushing the left throttle stick down descends the drone.
• When the throttle stick returns to the neutral position, the drone maintains its current height.

Hover up and down

Push the throttle up or down to make the quadcopter fly upward or downward.

Forward and backward

Push the direction lever up or down to make the quadcopter fly forward or backward.

Turn left and right

Pull the throttle left or right to make the quadcopter turn left or right.

Sideward fly

Pull the direction lever left or right to make the quadcopter fly to the left or right side.

Sideward fly fine-tuning

If the quadcopter drifts left or right, use the fine-tuning button to correct the drift.

Forward and backward fly fine-tuning

If the quadcopter drifts forward or backward, use the fine-tuning button to correct the drift.

1. Before pairing, place the drone facing forward with its tail towards the pilot (Pic.8). After takeoff, press the Headless Mode button on the remote control. The "NORMAL" LED light will turn off, and the "HEADLESS" LED light will turn on (Pic.9).
2. In Headless Mode, the drone's orientation does not matter. Any side can face forward. Use the throttle and direction sticks to control movement.
3. Press the Headless Mode button again to exit Headless Mode. The "HEADLESS" light turns off, and the "NORMAL" light turns on.

The One Key Return function automatically brings the drone back to the pilot. Press the One Key Return button.

• In Normal Mode: The drone returns to the direction it was pointing when paired (Pic.10).
• In Headless Mode: The drone returns to the direction it was pointing when Headless Mode was activated.

Once familiar with basic controls, perform advanced tumbling actions. Fly the drone to approximately 3 meters, press and hold the Tumbling Key, and push the right control lever forward/backward/left/right. This initiates tumbling actions. Tumbling is not available in Headless Mode.

Caution: The battery's full charge ensures the best tumbling performance.

The camera is pre-installed. Check the camera wire connections.

Connect to the camera's WIFI signal "HolyStoneFPV***" and open the "Deerc FPV" APP on your phone to use the camera function.

A phone holder is included for FPV functionality.

1. Insert the phone holder stick into the middle top hole of the remote control (Pic.12).
2. Rotate the phone holder to secure it to the plastic tag on the remote control (Pic.13, Pic.14).
3. Lock the phone holder by clockwise tightening the black plastic screw (Pic.14).

The drone supports FPV real-time camera and gravity sensor control. Download the appropriate app.
