Core Features & Benefits

1. Flagship H7-Grade MCU with Top-Tier Computing Power

Powered by the STM32H743 high-performance Cortex-M7 core MCU, it delivers significantly higher clock speed and computing power than the F7 series, representing the first-tier configuration in the RC flight controller industry. It easily supports higher gyro refresh rates, multi-layer dynamic filtering algorithms and complex function plugins, with lower latency and higher accuracy in attitude calculation. It handles both extreme maneuvering in high-speed racing and complex navigation operations for long-range fixed-wing flight with ease, providing professional pilots with ultimate tuning space and performance ceiling.

2. High-Precision 6-Axis Gyroscope for Accurate & Smooth Attitude Perception

Equipped with the industrial-grade ICM42688P 6-axis gyroscope and accelerometer, it features excellent low noise, high vibration resistance and minimal temperature drift. Leveraging the strong computing power of the H7 main controller, it enables finer filtering tuning and attitude calculation, effectively filtering out high-frequency vibration interference from the airframe. It delivers accurate and sensitive attitude perception, maintaining stable and smooth flight during high-speed flight and aggressive maneuvers, with greatly improved control responsiveness.

3. Flagship All-In-One Interfaces for One-Step High-End Assembly

The FC integrates all peripheral interfaces required for professional RC aircraft, eliminating the need for extra adapter boards to build a complete high-end aircraft system. The dedicated ELRS receiver port supports plug-and-play without soldering; the DJI-O port is fully compatible with DJI digital air units and transmits OSD FC data synchronously; dual camera ports support video switching; 2 servo ports perfectly fit fixed-wing and VTOL aircraft. With additional standard ports for GPS, LED strips, VTX and ESC, it greatly simplifies assembly wiring and reduces the risk of line interference.

4. Deep Compatibility with Open-Source Firmware, Full Advanced Features Unlocked

Fully compatible with mainstream open-source flight controller firmware including Betaflight, INAV and Emuflight. Relying on the super computing power of the H7 platform, it unlocks all advanced firmware features completely. It supports deep custom PID tuning, multi-stage filter parameter configuration and navigation function expansion. Pilots can perform extreme performance tuning according to flight scenarios, building both ultimate racing drones and long-range fixed-wing systems with complex route cruise, with unlimited gameplay expansion.

5. Industrial-Grade Optimized Design for Reliable Extreme Operation

It adopts industry-standard mounting holes and optimized hardware layout, perfectly fitting most high-end aircraft such as 5-inch racing drones, medium and large fixed-wing planes, and VTOL craft. The optimized power supply and wiring design effectively reduces electromagnetic interference and improves operation stability under extreme working conditions such as high load and long-time flight, meeting the strict requirements of professional competitions and long-duration operations.
