Figure 2: The aircraft features a module battery and a low battery alert system. Two batteries provide approximately 40 minutes of flight time.
4.2 Installing Batteries in the Remote Control
- Open the battery compartment on the back of the remote control.
- Insert 2 C batteries (included), ensuring correct polarity (+/-).
- Close the battery compartment securely.
4.3 Pairing the Aircraft with the Remote Control
- Place the aircraft on a flat surface.
- Turn on the aircraft's power switch. The LED lights on the aircraft will flash.
- Turn on the remote control.
- Push the left joystick (throttle) all the way up, then all the way down. The aircraft's LED lights will stop flashing and remain solid, indicating successful pairing.
5. Operating Instructions
5.1 Basic Flight Controls
- Takeoff: Press the One-Key Takeoff button or push both joysticks outwards and downwards simultaneously to start the propellers, then push the left joystick up to ascend.
- Landing: Press the One-Key Landing button or pull the left joystick down to descend.
- Ascend/Descend: Use the left joystick (throttle) up/down.
- Forward/Backward: Use the right joystick up/down.
- Turn Left/Right: Use the left joystick left/right.
- Fly Left/Right (Strafe): Use the right joystick left/right.
- Speed Adjustment: Press the speed button on the remote control to cycle through three speed modes (low, medium, high).

5.2 Headless Mode
In Headless Mode, the aircraft's orientation is locked to the remote control's orientation at the time of activation. This means pushing the right joystick forward will always make the aircraft fly away from you, regardless of which way the front of the aircraft is facing.
- To activate Headless Mode, press the Headless Mode button on the remote control. The aircraft's lights will flash to indicate activation.
- To exit Headless Mode, press the Headless Mode button again.
5.3 Altitude Hold
The Altitude Hold function allows the aircraft to maintain a stable altitude without constant throttle input. This makes it easier to control and capture stable photos/videos.
