5. Setup
5.1 Battery Charging
- Connect the drone battery to the USB charging cable.
- Plug the USB cable into a 5V/2A USB power adapter (not included).
- The indicator light on the battery will show charging status (e.g., red for charging, green for fully charged).
- Charging time is approximately 120-150 minutes per battery. Ensure all three batteries are fully charged before flight.
5.2 Propeller Installation
The propellers are marked with 'A' or 'B'. Match them to the corresponding motor arms as indicated on the drone.
- Unfold the drone arms carefully.
- Identify the 'A' and 'B' markings on the propellers and motor bases.
- Attach the propellers to the correct motor shafts and secure them with the provided screws using the screwdriver. Ensure they are firmly attached but not overtightened.
5.3 Controller Preparation
- Ensure the remote controller is fully charged.
- Extend the antenna (if applicable) and any phone holder.
5.4 Power On/Off
- Power On Drone: Insert a charged battery into the drone. Press and hold the power button on the drone until the indicator lights turn on.
- Power On Controller: Press and hold the power button on the remote controller until the screen lights up.
- Power Off: Reverse the power-on steps, ensuring both drone and controller are powered off after use.
6. Operating Instructions
6.1 Pairing the Drone and Controller
- Place the drone on a flat, level surface.
- Power on the drone, then power on the remote controller.
- Push the left joystick (throttle) all the way up, then all the way down. The drone's indicator lights will stop flashing and become solid, indicating successful pairing.
- Wait for GPS signal acquisition. The drone's lights will flash slowly once GPS is locked. This may take a few minutes outdoors.
6.2 Basic Flight Controls
| Control Stick | Movement | Action |
|---|---|---|
| Left Stick (Throttle) | Up | Ascend |
| Left Stick (Throttle) | Down | Descend |
| Left Stick (Yaw) | Left/Right | Rotate Left/Right |
| Right Stick (Pitch) | Up/Down | Fly Forward/Backward |
| Right Stick (Roll) | Left/Right | Fly Left/Right (Sideways) |
Use the one-key takeoff/landing button for easy automated flight initiation and termination.
6.3 GPS Functionality
The built-in GPS system provides precise positioning and stable hovering. Once GPS is locked, the drone will maintain its position even in light winds. The Return-to-Home (RTH) function allows the drone to automatically return to its takeoff point when activated or in case of low battery/signal loss.
6.4 Obstacle Avoidance
The drone is equipped with intelligent obstacle avoidance sensors. When activated, the drone will automatically detect and maneuver around obstacles in its path, enhancing flight safety. Always monitor the drone's surroundings, as obstacle avoidance may have limitations in certain conditions (e.g., very thin objects, reflective surfaces, or extreme lighting).
6.5 Dual Camera Operation
The drone features a main front camera for high-resolution aerial photography and video, and a bottom optical flow camera for improved stability at lower altitudes.
- Photo Capture: Press the dedicated photo button on the remote controller to take a still image.
- Video Recording: Press the dedicated video button to start recording. Press again to stop.
- Camera Angle Adjustment: Use the designated button or dial on the controller to adjust the main camera's tilt angle.
- Viewing Footage: Footage is saved to an inserted SD card (not included) or can be viewed live on the controller's screen.
6.6 Special Features
The SG901 MAX drone can perform exciting aerial maneuvers, such as tumbling. Refer to the controller's specific button layout for activating these features. Ensure sufficient altitude and clear surroundings before attempting any special maneuvers.
7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your drone.
- Battery Care: Store batteries in a cool, dry place. Do not fully discharge batteries for extended periods. Charge them to about 50-60% for long-term storage.
- Cleaning: Use a soft, dry cloth to clean the drone body and camera lens. Avoid using harsh chemicals.
- Propeller Inspection: Regularly check propellers for cracks, bends, or damage. Replace damaged propellers immediately using the spare parts provided.
- Motor Inspection: Ensure motors are free from debris and spin smoothly.
- Storage: When not in use, fold the drone arms and store it in a protective case or its original packaging to prevent damage.
