G-F1 FPV FC
The G-F1 FPV flight controller is designed for fixed-wing, UAV, and VTOL applications. Powered by the STM32F405 processor with a high-precision IMU and integrated sensors, it delivers accurate flight control.
The G-F1 supports open-source firmware including Betaflight and INAV. Its compact design fits small frames perfectly.
