FlyingRC F4 Wing Mini Fixed Wing Flight Controller with Type-C Interface
Take your micro fixed-wing builds to the next level with the FlyingRC F4 Wing Mini Flight Controller. Engineered for small and ultra-compact fixed-wing aircraft, this featherweight board packs serious processing power into a 27.9 × 20.3 × 11.2 mm footprint — weighing just 2.8 g. Whether you're flying an F80, ArwingMini, micro claw, or a modified hand-throw glider, this flight controller delivers high-performance stability, precise sensor data, and flexible connectivity in one tidy package.
Made in Mainland China.
Key Features
- Powerful STM32F405RGT6 Processor: ARM Cortex-M4 core running at 168 MHz with 1 MB Flash — over 5× more capable than competing mini FCs that rely on STM32F0-series chips.
- ICM42605 Gyroscope: 3rd-generation TDK sensor purpose-optimized for drone flight dynamics, delivering smooth and responsive attitude control.
- SPL06 Barometer: High-precision domestic barometer for reliable altitude hold and smooth flight.
- Dual Onboard LDO Regulators: Sensors are independently powered, reducing electrical noise for consistently stable flight.
- 7× PWM Outputs: Drive up to 7 servos or ESCs simultaneously, plus 3.5 serial ports (SBUS counts as half a serial port).
- Type-C Interface: Direct plug-in connection with superior durability and longevity. Connect to your smartphone via dual USB-C cables and configure via QGroundControl mobile app (AP firmware).
- Wide Voltage Input (2.5–30V / 1–6S LiPo): Supports up to 6S battery input via SH1.0 2-pin interface, with battery voltage also powering the HD image transmission port.
- HD Direct Plug-In Support: SH1.0 6-pin interface for HD OSD (compatible with Snail HD, OpenIPC, etc.). Note: analog OSD is not supported.
- ELRS Receiver Ready: Direct plug-in for ELRS receivers to keep your build as compact as possible.
- External I²C Ammeter Support: No onboard analog ammeter; connects to an external I²C protocol ammeter for current monitoring.
