I have got a Matek f722 fc. When i connect it to betaflight, the model of the drone in setup starts rotating automatically. the fc is placed flat without any disturbance. pls help
More than likely your Channel Map is wrong. Go to the Receiver tab and see if it is set to TAER1234 or AETR1234. Mine is AETR because that is what my TX is set to, it doesn't matter what it is as long as the quad and the TX are set to the same thing.
Maybe you might want to consider calibrating the accelerometer. If that doesn't work maybe try to flash the sofware. But I'm still a beginner so that might not work. Worth a try tho. Hopefully you figure it out. Good Luck!
