【Product Overview】

The F405 30.5×30.5 Flight Controller + 55A/65A 4in1 ESC Stack is designed for freestyle, racing, and long-range FPV drones that require responsive control, reliable power delivery, and stable performance. Powered by the STM32F405 main processor and the highly stable ICM42688P gyro, this stack offers precise flight handling and excellent anti-vibration performance—ideal for 5"–7" builds and mid-to-large FPV platforms.

The included 65A 4-in-1 ESC supports up to 6S LiPo, providing robust current handling with advanced electrical protection. Combined with multiple BEC outputs, 6 UART ports, full Betaflight compatibility, and convenient Type-C connectivity, this stack delivers a powerful and reliable solution for FPV enthusiasts and professionals.

⭐1. Powerful F4 Flight Controller with STM32F405 + ICM42688P Gyro

Equipped with a fast F4 processor and low-noise gyro, the FC ensures responsive control, better filtering, and high stability—perfect for freestyle, racing, and long-range drones.

⭐2. Dual BEC Power Output: 5V/2A + 12V/2A

Multiple regulated power outputs support cameras, VTX, receivers, LEDs, and GPS devices without voltage drops or video noise.

⭐3. Integrated OSD + Built-in Blackbox (16MB)

AT7456E OSD provides stable on-screen data, while the onboard 16MB Blackbox allows detailed tuning and flight log recording.

⭐4. 65A 4-in-1 ESC (3–6S) with TVS Protection

Delivers 65A continuous and 75A peak (5 seconds) per motor. TVS diode + external capacitor help suppress voltage spikes and ensure smooth, safe performance.

⭐5. Standard 30.5×30.5mm Mounting for Wide Compatibility

Fits a wide range of 5", 6", and 7" freestyle or long-range frames, providing maximum build flexibility.
