Description

The SpeedyBee F405 V4 BLS stack combines a robust flight controller and a powerful electronic speed controller into a single, compact unit. The flight controller’s STM32F405 processor handles rapid data computation, while the ICM42688P IMU delivers precise gyroscopic data for responsive and stable flight characteristics, essential for aggressive racing and freestyle maneuvers.

The integrated 4-in-1 ESC is rated for a continuous 55A per motor with a 70A burst capability, providing ample headroom for demanding motor setups on 3S to 6S LiPo batteries. The stack’s design includes a 1000uF low-ESR capacitor for clean power delivery and features like a built-in barometer and current sensor scaling enhance its functionality for advanced pilots using Betaflight or INAV.

Key Features

  • High-performance STM32F405 flight controller with ICM42688P gyro for low-latency control.
  • 4-in-1 55A BLHeli_S ESC supports DSHOT300/600 protocols for ultra-responsive motor signaling.
  • Integrated AT7456E OSD chip provides customizable real-time telemetry overlay directly in the FPV video feed.
  • Built-in barometric sensor enables altitude hold and variometer functions in supported firmware.
  • Type-C USB port ensures a reliable and reversible connection for configuration and firmware updates.
  • 30.5x30.5mm mounting footprint with 4mm holes for standard FPV frame compatibility.
  • Multiple UART ports allow for easy integration of GPS, telemetry, and ExpressLRS receivers.
  • Includes a pre-soldered 1000uF low-ESR capacitor to minimize voltage spikes and protect the ESC.

Applications

  • 5-inch FPV racing drones requiring a high-current 4-in-1 ESC and a feature-rich flight controller.
  • Freestyle quadcopters built on 30.5mm mounting frames needing integrated OSD and barometer for advanced flight modes.
  • INAV-based long-range or autonomous builds leveraging the multiple UARTs for GPS and telemetry modules.
  • High-performance 6S drone setups where the 55A continuous current rating ensures reliable motor control.

Frequently Asked Questions

What is the maximum LiPo cell count supported by this stack?

The SpeedyBee F405 V4 BLS stack is rated for a power input of 3S to 6S LiPo batteries. Its 55A continuous current rating per motor provides sufficient headroom for high-performance 6S setups commonly used in modern racing and freestyle drones.

Which flight firmware is pre-installed and supported?

The stack comes pre-configured with Betaflight firmware. It is also fully compatible with INAV firmware, allowing pilots to choose between a performance-tuned racing setup or a feature-rich platform for autonomous navigation and long-range flight.

Does the package include the necessary capacitor for installation?

Yes, a 1000uF low-ESR capacitor is included in the package. This capacitor should be soldered to the main battery input pads on the ESC to help filter voltage spikes and ensure clean, stable power delivery to the flight controller and ESCs, which is critical for reliable operation.

What mounting pattern does this FC & ESC stack use?

The stack uses a standard 30.5mm x 30.5mm mounting pattern with 4mm diameter holes. This makes it compatible with the vast majority of FPV racing and freestyle drone frames designed for 30x30mm components. Standard M3 screws and nylon standoffs are used for installation.
