Flight Stack HAKRC F7 70A

The HAKRC F7 70A flight stack is designed for FPV drones that operate under heavy loads with large propellers. It is ideal for builds, where stable power delivery and component endurance are critical.

Its power stage features a 70 A ESC (80 A burst). Running on BLHeli_32 firmware, it supports modern motor control protocols, delivers smooth throttle response, and allows pilots to fine-tune their drone for specific missions. The built-in current sensor provides accurate telemetry, while the LC filter keeps video signals clean even under heavy load.

At the core lies the STM32F7 MCU, which ensures fast data processing and stable performance. With multiple UART ports, it can handle GPS, telemetry, and sensor connections for complex builds. A 16 MB Blackbox is included for flight logging and detailed analysis, making it easier to fine-tune.

The stack uses the standard 30.5×30.5 mm mounting format, making it compatible with most frames, and weighs around 22 g — an optimal figure for this class of hardware.

The HAKRC F7 70A delivers durability, stability, and precise control, making it a reliable choice for FPV drones running larger propellers and demanding robust electronics.
