I just built this drone I have never built before and I don't think this sound is normal (refer to video) the grinding sound happens whenever I pitch, yaw, or roll but does not happen when it is idling, any ideas why this could be happening or if it is supposed to happen and I am just a dumb noob?

Video

give it a short try outside with props on.
while it doesnt sound like it should, testing without rotors doesnt give usable informations.

It functions fine still makes the noise though.

Sounds more like a loose magnet or two.

Props off.

In the motors tab of betaflight, run each motor one at a time.

Is the sound across all of them?

It only happens when pitch, roll, or yawing, does not happen when turning them on in betaflight.

tell us more about the build, maybe some pictures

is there a capacitator attached?

Yes, there is a capacitor, it is the analog version of Oscar Liangs build.

It's generally a bad idea to run motors from the radio with the props off, use the motors tab in BF. The PID controller is expecting some resistance from props and strange things can happen when it doesn't get that. If it doesn't occur when flying with the props on nor when using the motors tab I wouldn't worry about it.

Have you tuned it yet? Pulling a few punch outs, flips, rolls and yaw spins with BF defaults somewhere reasonably safe and checking out the black box logs may give more useful info

what motors and esc do you use?
