When you start it, one of the propellers may be damage due to odd sounds. Level all motors in the middle.

I have the same problem, if you're drunk does that what I recommend doing is putting a black and white motor in the top right, a red and blue with the top left corner, a red and blue bottom right corner, and a black and white in the bottom right

Pretty sure you put a clockwise propellor where a counterclockwise propellor was supposed to go. I was pulling my hair out on mine until I realized I forgot to replace one of the propellers on my son’s drone.

I just bought the BetaFPV Cetus with brush motors. 2 questions, How do I upgrade to brushless? and what are the advantages?

Your motor has been pushed to far down pull it up alittle on whichever is crating the sound
