Flight Stack HAKRC F4 65A

The HAKRC F4 65A flight stack combines a robust power stage with the proven stability of the F4 controller. It is designed for pilots flying larger drones who require more headroom in power and endurance.

At its core is the STM32F4 MCU with a precise gyro, ensuring predictable control and stable handling even during aggressive maneuvers. Multiple UART ports make the system flexible, allowing easy integration of GPS, telemetry, and additional peripherals.

The 65 A ESC running BLHeli_32 is optimized for 4–6S LiPo batteries and can withstand bursts up to 75 A, offering reliability during extended, high-demand flights. This makes it ideal for drones with 6–9 inch propellers, where extra durability is essential.

A built-in current sensor provides accurate energy consumption data, while the integrated LC filter reduces electromagnetic interference, ensuring stable operation of video systems. Together, these features give pilots clean signals and confidence in their platform.

With the standard 30.5×30.5 mm mounting pattern, the stack fits most modern frames. The HAKRC F4 65A is a perfect choice for those who want to go beyond entry-level solutions and equip mid-size drones with reliable, well-balanced performance.
