Axisflying Argus Mini FC+ESC Stack — F722 + 40A 4–6S 32Bit

The Axisflying Argus Mini FC+ESC Stack combines an STM32F722 flight controller and a 40A 32-bit 4–6S 4-in-1 ESC in a compact 20x20 mm form factor. Built with a full aluminium CNC heatsink casing for structural rigidity and thermal management, this mini stack is engineered for 3.5-inch to 5-inch freestyle, racing, and cinematic builds where frame space is limited.

Key features

• Full aluminium CNC heatsink enclosure protects the PCB components from physical crash impact while actively dissipating thermal buildup during high-current draws.
• Features a BMI270 gyroscope, 16 MB blackbox flash storage, and 6 hardware UARTs to support digital video units, GPS modules, and external receivers.
• Dual integrated BECs delivering clean 5 V / 2 A for logic peripherals and a dedicated 9 V / 2 A circuit optimized to power DJI O3, Walksnail Avatar, or HDZero air units.
• 40 A continuous (45 A burst) 32-bit 4-in-1 ESC provides smooth, high-frequency motor control with bi-directional DShot and full telemetry support.
• Dedicated plug-and-play harness port for digital HD video transmitters alongside well-spaced solder pads for versatile wiring configurations.

Designed specifically for lightweight quadcopters that cannot accommodate a standard 30.5x30.5 mm stack without adding unnecessary bulk. Fits cleanly inside sub-250g 3.5-inch freestyle frames, lightweight 4-inch long-range cruisers, and compact 5-inch racing quads needing high processing capacity and direct digital video integration.
