3. Setup

3.1 Propeller Installation

1. Ensure the drone is powered off and the battery is disconnected.
2. Identify the correct rotation direction for each propeller. Propellers are typically marked with 'R' for clockwise rotation or are unmarked for counter-clockwise rotation.
3. Align the propeller with the motor shaft and secure it using the provided screws. Do not overtighten.
4. Verify that all propellers are securely attached and can spin freely without obstruction.

3.2 Battery Installation

1. Use a recommended 2S 18650-3000mAh LiPo battery.
2. Carefully insert the battery into the designated battery tray or strap it securely to the frame using a battery strap (not included).
3. Connect the battery's XT30 or XT60 connector to the drone's power input. Ensure correct polarity.

3.3 Receiver Binding (ELRS / TBS Nano)

If your drone did not come pre-bound, you will need to bind the ELRS or TBS Nano receiver to your compatible radio transmitter. Refer to the specific binding instructions for your ELRS or TBS Nano module and radio transmitter.

3.4 Flight Controller Software Configuration

The HGLRC SPECTER 15A ELRS AIO flight controller typically runs Betaflight or INAV firmware. Connect the drone to a computer via USB and use the respective configurator software (e.g., Betaflight Configurator) to:

• Calibrate accelerometers and gyroscopes.
• Configure receiver settings and channel mapping.
• Set up flight modes and arming switches.
• Adjust PID tuning (advanced users).

4. Operating Instructions

4.1 Pre-Flight Checks

1. Ensure the battery is fully charged and securely installed.
2. Verify all propellers are correctly installed and free from damage.
3. Check that the radio transmitter is powered on and correctly bound to the drone.
4. Inspect the drone for any loose wires, screws, or damaged components.
5. Confirm your FPV goggles or monitor are receiving a clear video feed.
6. Perform a range check of your radio control system in the intended flight area.

4.2 Arming and Disarming

The drone's motors will not spin until it is armed. Arming procedures are typically configured in the flight controller software:

• Arming: Move the designated arming switch on your radio transmitter to the 'armed' position, or perform the stick command (e.g., throttle down and yaw right). The motors will start spinning slowly.
• Disarming: Move the arming switch to the 'disarmed' position, or perform the stick command (e.g., throttle down and yaw left). The motors will stop.

Always arm and disarm in a safe, clear area.

4.3 Basic Flight Controls

Standard FPV drone controls typically include:

• Throttle: Controls altitude (left stick up/down).
• Yaw: Rotates the drone horizontally (left stick left/right).
• Pitch: Tilts the drone forward/backward (right stick up/down).
• Roll: Tilts the drone left/right (right stick left/right).

4.4 Landing

To land, slowly reduce the throttle while maintaining control over pitch and roll. Once the drone is on the ground, immediately disarm the motors.

5. Maintenance

5.1 Propeller Inspection and Replacement

Regularly inspect propellers for cracks, bends, or nicks. Damaged propellers can cause instability and reduce flight efficiency. Replace any damaged propellers immediately with new ones of the same type (3520 3.5-inch 3-blade).

5.2 Battery Care

• Always use a LiPo charger designed for 2S batteries.
• Do not overcharge or over-discharge batteries.
• Store batteries at a storage voltage (typically 3.8V per cell) when not in use for extended periods.
• Inspect batteries for swelling or damage before each flight. Discontinue use of damaged batteries.

5.3 Cleaning

Gently clean the drone's frame and components with a soft, dry brush or compressed air. Avoid using liquids directly on electronic components.

5.4 Firmware Updates

Periodically check the manufacturer's website or the Betaflight/INAV project pages for firmware updates for your flight controller. Updates can provide performance improvements, new features, or bug fixes. Follow official instructions carefully when performing firmware updates.

6. Troubleshooting

• Drone not arming: Check receiver connection, radio transmitter settings, and flight controller arming conditions in Betaflight/INAV configurator. Ensure throttle is at its lowest point.
• No video feed: Verify VTX power, antenna connection, and FPV goggle/monitor channel. Check for damage to the camera or VTX.
• Unstable flight: Inspect propellers for damage, ensure motors are clean, and check flight controller settings (PIDs, calibration).
• Loss of control: Immediately disarm the drone. Check receiver binding, antenna placement, and signal strength. Avoid flying beyond the range of your radio system.
• GPS not locking: Ensure the drone has a clear view of the sky. Allow sufficient time for satellite acquisition. Check GPS module connection.

8. Safety Information

Operating FPV drones requires caution and adherence to safety guidelines:

• Local Regulations: Always comply with local aviation laws and regulations regarding drone operation. This includes airspace restrictions, registration requirements, and privacy laws.
• Flight Environment: Fly in open areas, away from people, animals, buildings, and obstacles. Avoid flying near airports or restricted zones.
• Weather Conditions: Do not fly in strong winds, rain, snow, or other adverse weather conditions.
• Battery Safety: Handle LiPo batteries with extreme care. Do not puncture, short-circuit, or expose them to extreme temperatures. Charge them in a fire-safe location.
• Propeller Safety: Keep hands and face clear of spinning propellers. They can cause serious injury.
• Line of Sight: Maintain visual line of sight with your drone, even when flying FPV, unless local regulations permit otherwise.
• Pre-Flight Checks: Always perform thorough pre-flight checks as outlined in this manual.
