Skystars H7 Dual Gyro HD Flight Controller

The Skystars H7 Dual Gyro HD is a 30.5x30.5mm flight controller built for 5-inch freestyle, cinelifter and long-range digital FPV builds. A fast STM32H743 processor and a dual-BMI270 gyro layout give firmware more data to filter out vibration noise, and a dedicated 10V VTX output wires straight into DJI, Walksnail or HDZero air units.

Key features

• Dual BMI270 gyros let Betaflight cross-check or fail over between sensors on a vibration-heavy frame
• 480MHz STM32H743 processor with headroom for demanding filtering and fast PID loop rates
• Dedicated, switchable 10V power feed and a plug-in port for digital HD video transmitters
• Built-in analogue video switcher accepts two cameras when running a traditional OSD instead of digital HD
• 16MB onboard blackbox flash for detailed PID tuning and vibration analysis
