Proper installation is crucial for the performance and safety of your FPV drone or RC airplane. Always refer to the specific wiring diagrams for your frame and components.

4.1. Licheke tsa ho Kena Pele

• Ensure your workspace is clean and static-free.
• Etsa bonnete ba hore likarolo tsohle li teng ebile ha lia senyeha.
• Gather necessary tools: soldering iron, solder, flux, wire cutters, heat shrink tubing, multimeter.

4.2. Mounting the ESC Stack

1. Hokela damping pads to the mounting holes on your frame.
2. Carefully place the 4-in-1 ESC board onto the damping pads, aligning the mounting holes.
3. Place the flight controller board on top of the ESC, ensuring proper orientation and alignment.
4. Secure the stack using the provided nuts or standoffs, ensuring not to overtighten.

4.3. Wiring Connections

Connect the ESC stack to your drone's power distribution board (PDB) or direct battery connection, motors, receiver, and other peripherals. Always double-check polarity before powering on.

• Kenyeletso ea Matla: Solder the main battery leads (red for positive, black for negative) to the designated pads on the 4-in-1 ESC. Ensure the capacitor is soldered across the main battery pads for voltage spike suppression.
• Khokahano ea makoloi: Solder the three motor wires from each motor to the corresponding motor pads on the ESC. The order of wires may need adjustment in software for correct motor direction.
• Flight Controller to ESC: Use the provided connecting wire harness to link the flight controller to the 4-in-1 ESC. This typically carries telemetry, current sensing, and motor control signals.
• Khokahano ea Moamoheli: Connect your receiver (SBUS, PPM, or Spektrum) to the appropriate UART port on the flight controller. Refer to the flight controller's pinout diagram.
• Other Peripherals: Connect FPV camera, video transmitter (VTX), GPS, or other accessories to the designated pads/ports on the flight controller, paying attention to voltage requirements (5V/9V BEC outputs are available).

4.4. Firmware Configuration

The flight controller supports Betaflight and Cleanflight firmware. The ESCs utilize BLHeli_S firmware.

1. Motsamaisi oa Sefofane: Connect the flight controller to your computer via USB. Use the Betaflight Configurator or Cleanflight Configurator software to flash the latest firmware and configure settings such as PID tuning, motor output, receiver protocols, and OSD.
2. Li-ESC: Use the BLHeliSuite software (accessible through Betaflight/Cleanflight passthrough) to configure ESC settings, calibrate motors, reverse motor direction if needed, and update BLHeli_S firmware.

• Confirm radio control link and arming switch functionality.

5.2. Powering On and Arming

1. Connect the flight battery to the ESC stack. You should hear a series of beeps indicating successful initialization.
2. Beha drone sebakeng se lekaneng.
3. Arm the motors using your configured arming switch on your radio transmitter. The motors will typically spin slowly or make a distinct sound to indicate they are armed.

5.3. Throttle Modes

The ESC supports various throttle protocols for precise motor control:

• DShot300/600: Digital protocol offering high resolution and noise immunity. Recommended for optimal performance.
• Multishot: Analog protocol, faster than Oneshot.
• Oneshot125: Analog protocol, faster than standard PWM.
• PWM: Standard analog protocol, generally not recommended for FPV drones due to latency.

Select the desired throttle mode in your flight controller software (e.g., Betaflight Configurator).

6. Tlhokomelo

Regular maintenance helps ensure the longevity and reliability of your ESC stack.

• Tlhahlobo ea Pono: Periodically check for any signs of physical damage, loose connections, or burnt components.
