SpeedyBee F405 V5 OX32 55A 30×30 FC & ESC Stack

The SpeedyBee F405 V5 OX32 stack pairs a feature-rich F405 flight controller with a robust 55A 4-in-1 ESC. Engineered for demanding 5-inch freestyle drones, aggressive racers, and 7-inch long-range builds, this system drops into any frame with a standard 30.5x30.5mm mounting pattern. The introduction of the OX32 32-bit ESC architecture delivers exceptionally smooth throttle resolution and handles high-torque motor setups with ease. True to the SpeedyBee ecosystem, the flight controller features built-in wireless connectivity, allowing pilots to adjust tunes, configure peripherals, and check motor direction directly from a smartphone without needing a laptop.

Key features

• Wireless configuration: Integrated Bluetooth enables complete setup and field tuning via the SpeedyBee mobile app.
