Know before you buy
The G4 processor runs at 180MHz and includes a dedicated math accelerator, which allows for faster loop times and more precise flight calculations. This results in significantly smoother flight performance compared to older F4 or F7-based flight controllers.
Yes, while the board is optimized for the FETtec ecosystem with solderless connectors, it still includes traditional solder pads. This gives you the flexibility to use it with almost any standard ESC on the market.
Yes, the board comes with a 30x30mm mounting pattern and features removable tabs that allow it to fit into 20x20mm frames. This makes it a versatile choice for a wide range of drone builds.
The true power-cutting Pit Mode allows you to completely cut power to your video transmitter when the drone is on the ground. This prevents your VTX from overheating while you are working on your settings or waiting at the flight line.
The FETtec FC G4 features a full graphic OSD designed specifically for the FETtec ecosystem. It provides live data overlays, but ensure your chosen FPV system is compatible with the FETtec OSD implementation before installation.
The board supports an input voltage range of 6V to 27V, making it compatible with 2S through 6S LiPo batteries. It also includes switchable BEC outputs to provide clean 5V or 16V power to your receiver and video transmitter.
