Description:
The Holybro FETtec FC G4 features the latest STM32 G4 MCU with math accelerator for the ultimate in-flight performance, onboard OSD for KISS flight tuning, 2 dedicated BECs for 5V and 16V switchable power, DSHOT2400 outputs for support of up to 8 motors, and dual 20x20 and 30x30 mounting holes.Note:
Currently, the Holybro Fettec FC G4 does not support BLHeli_32 ESC Configuration via FC Passthrough and BLHeli_32 ESC telemetry/current reading. An Betaflight Flight Controller is needed to configure BLHeli32 ESC Setting.
