The FETtec FC G4 features the latest STM32G4 processor. Providing unparalleled processing power to your aircraft. Along with an IIM-42652 SPI gyro, two 5v BECs, 6-27V (2-6S) power handling, and a host of other features, the G4 from FETtec is on the cutting edge of Flight Controller technology.

Check out our large variety of Flight controllers , KISS Keychain Configurator V1.2 for Fettec Flight controllers and the rest of our Fettec Collection!

The next generation of FETtec's popular KISS flight controller has arrived! Featuring the latest STM32 G4 MCU with math accelerator for the ultimate in flight performance, IIM-42652 SPI gyro, 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.

This new "N" version simply means there is no onboard analog OSD chip. Due to global shortages, the OSD chip was removed. This only affects analog systems, there are no other restrictions and you can use the full potential of this FC as you are used to. The use of external OSD boards and digital FPV systems still work fine.
