Foxeer F405 V2 FC Reaper 55A ESC 8S Stack

The Foxeer F405 V2 FC Reaper 55A ESC 8S Stack is an integrated flight-control and motor-control solution designed for advanced FPV drone builds. It combines the Foxeer F405 V2 flight controller with the Reaper 55A 4-in-1 electronic speed controller, providing the essential control hardware for a four-motor brushless drone.

The flight controller uses the STM32F405RGT6 processor and ICM42688-P gyroscope to process flight data and manage drone stabilization. Its DPS310 barometer provides altitude measurement, while the onboard Betaflight OSD and flash memory support flight information display and black box recording.

The Reaper 55A ESC supports four brushless motors, with 55A continuous current and 80A burst current per channel. It supports 3S–8S LiPo batteries and BLHeli_32 firmware, offering compatibility with several common ESC control protocols.

With six UART ports, USB Type-C, DJI connectivity, GPS/compass connections, camera switching, and SmartAudio support, the stack offers flexible integration options for FPV electronics. Its standard 30.5 × 30.5mm mounting pattern allows installation in compatible drone frames.

How to Use

1. Install the flight controller and ESC using the supplied silicone grommets and compatible mounting hardware.

2. Connect the FC and ESC using the supplied FC-to-ESC cable.

3. Solder the battery power leads and four brushless motor wires to the ESC according to the board markings.

4. Connect the FPV camera, VTX or compatible DJI digital video system using the appropriate connectors and wiring diagrams.

5. Connect the GPS, compass, receiver, and other peripherals to the appropriate ports.

6. Connect the flight controller to a computer through USB Type-C.

7. Configure the flight controller using the appropriate Betaflight or supported ArduPilot software.

8. Configure the ESC settings and motor protocol according to the selected firmware.

9. Verify motor order, motor direction, receiver inputs, and failsafe settings before installing propellers.

10. Perform a careful bench test and check all electrical connections before the first flight.

Important Notes

• The ESC supports 3S–8S LiPo batteries, but always verify the complete power-system requirements and battery voltage before connecting a battery.

• The FC and ESC have separate power specifications. Follow the official wiring diagram when supplying power to the stack.

• The ESC does not include a separate BEC; the 5V and 10V BEC outputs are provided by the flight controller.

• The 55A continuous and 80A burst ratings apply to each of the four ESC channels, subject to adequate cooling and operating conditions.

• Use a suitable low-ESR capacitor on the battery input as recommended for high-voltage FPV builds.

• Check motor connections carefully to prevent short circuits and incorrect wiring.

• Verify connector pinouts before connecting DJI systems, GPS modules, cameras, or VTX equipment.

• Remove all propellers during configuration, firmware updates, and motor testing.

• Ensure the frame supports the 30.5 × 30.5mm mounting pattern.

• BLHeli_32 and flight-controller firmware compatibility may depend on the installed firmware version and configuration.
