SpeedyBee F405 V3 BLS 50A 30x30 FC & ESC Stack

SpeedyBee F405 V3 BLS 50A Stack for Confident FPV Builds

The SpeedyBee F405 V3 BLS 50A 30×30 FC & ESC Stack is designed for pilots who want a reliable, configurable flight system that is straightforward to set up and consistent in the air. Combining a capable F4 flight controller with a robust 4-in-1 ESC, this stack delivers stable control, responsive handling, and flexible tuning options for a wide range of 3-6S multirotor builds.

The F405 flight controller is built around the STM32F405 processor, providing fast signal processing for smooth flight performance and precise control response. With a standard 30×30 mm mounting pattern, it fits easily into most 5-inch and larger frames. Integrated Bluetooth allows you to configure key parameters directly from your smartphone via the SpeedyBee mobile app, reducing reliance on a laptop at the field. Betaflight OSD support lets you monitor voltage, current draw, flight mode, and other critical data directly in your FPV feed, so you can keep track of your craft's status while flying.

The included BLHeli_S 50A 3-6S 4-in-1 ESC is engineered to handle high current draw typical of modern FPV motors, helping maintain consistent power delivery during punch-outs and aggressive maneuvers. It supports 3-6S LiPo input and is designed for efficient heat dissipation under sustained load. The stack supports SBUS, IBUS, PPM, and RSSI input, making it compatible with most popular radio systems. Additional features include FPV camera control for in-camera OSD and settings adjustment, as well as a VTX power switch that lets you remotely control your video transmitter power, useful for pit mode and channel changes in group flying environments.

Why It's a Smart Choice

• Integrated FC and 4-in-1 ESC stack simplifies wiring and reduces build complexity.
• Bluetooth configuration and Betaflight OSD provide convenient setup and in-flight telemetry.
• 50A BLHeli_S ESC supports demanding 3-6S FPV builds with consistent power delivery.
