Flight Stack HAKRC F7 55A

The HAKRC F7 55A is a flight stack designed for pilots who need a modern controller with future-proof performance. At its core is the STM32F7 MCU, which offers higher clock speed and faster data processing compared to F4 chips. This allows the stack to handle multiple peripherals without compromising stability.

The controller supports an extended number of UART ports, making it easy to connect GPS, telemetry, sensors, and other peripherals. A 16 MB Blackbox is included for flight logging and fine-tuning, while the integrated LC filter keeps signals clean and ensures stable operation with powerful video transmitters.

The power stage features a 55 A ESC (65 A burst) running BLHeli_32 firmware, optimized for 4–6S LiPo batteries. It is well-suited for FPV drones with 5–7 inch propellers, delivering smooth response and supporting modern motor control protocols for precise tuning.

A built-in current sensor provides accurate telemetry, helping pilots monitor consumption and manage energy more effectively — especially during long missions or near the limits of battery capacity.

All of this comes in the standard 30.5×30.5 mm mounting format, with a total weight of around 20 g. The HAKRC F7 55A offers a powerful controller, versatile functionality, and a reliable ESC in one compact and well-balanced solution.
