2. Power on the drone. The LED lights will flash.
3. Power on the remote control.
4. Push the left operating lever (throttle) all the way up, then pull it all the way down. The drone's LED lights will stop flashing and remain solid, indicating successful pairing.

2. Gyroscope Calibration

After pairing, push both operating levers down and to the right simultaneously for 2-3 seconds. The drone's lights will flash rapidly and then become solid, indicating successful calibration. This ensures stable flight.

3. Takeoff and Landing

One-Key Takeoff

After pairing and calibration, press the One Touch Takeoff/Landing button. The drone will automatically ascend and hover at a certain altitude.

Manual Takeoff

After pairing and calibration, slowly push the left operating lever (throttle) upwards. The propellers will spin, and the drone will ascend.

One-Key Landing

During flight, press the One Touch Takeoff/Landing button. The drone will automatically descend and land gently.

Manual Landing

Slowly pull the left operating lever (throttle) downwards until the drone lands. Once landed, pull the lever all the way down to stop the propellers.
