4. Configuración e instalación
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. Comprobaciones previas a la instalación
- Ensure your workspace is clean and static-free.
- Verifique que todos los componentes estén presentes y sin daños.
- Gather necessary tools: soldering iron, solder, flux, wire cutters, heat shrink tubing, multimeter.
4.2. Mounting the ESC Stack
- Adjunte la damping pads to the mounting holes on your frame.
- Carefully place the 4-in-1 ESC board onto the damping pads, aligning the mounting holes.
- Place the flight controller board on top of the ESC, ensuring proper orientation and alignment.
- Secure the stack using the provided nuts or standoffs, ensuring not to overtighten.

4.3. Conexiones de cableado
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.
- Entrada de energía: 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.
- Conexiones de motores: 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.
- Controlador de vuelo a 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.
- Conexión del receptor: Connect your receiver (SBUS, PPM, or Spektrum) to the appropriate UART port on the flight controller. Refer to the flight controller's pinout diagram.
- Otros periféricos: 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. Configuración de firmware
The flight controller supports Betaflight and Cleanflight firmware. The ESCs utilize BLHeli_S firmware.
- Controlador de vuelo: 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.
- 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.
5. Instrucciones de funcionamiento
Once installed and configured, the Keenso F4 V3S PLUS ESC Stack is ready for operation.
5.1. Comprobaciones previas al vuelo
- Asegúrese de que todas las conexiones estén seguras y libres de cortocircuitos.
