The SpeedyBee F405 V4 stack is here, and it’s built for large FPV drones and cinelifters running Betaflight or INAV. From the iconic yellow soft mounts to the aluminum alloy heatsink on the 4-in-1 ESC, this stack delivers both style and performance.
With 60A continuous and 70A burst current ratings, it’s a big upgrade from the V3’s 50A, making it the perfect choice for 8-inch or 10-inch prop drones.
