Hello there, I want to ask a question about propellers. While taking off and gaining height, I can hear a small buzz from time to time. It's hard to explain since the propellers normally make a lot of noise, but I find it a little bit suspicious. Also while descending I heard it before landing. While training in the past days, I touched the propellers without damaging them, they're not bent at all, at least to my eye, but who knows, I'm still a newbie. Is it normal or I should change them?
Hope to be understood, thanks for your time.

After landing, does the intermittent buzz continue? About once per second?  Flashing red LED on rear and props on any motor twitching?  This is usually an indication of a problem with the props on that motor. Earlier posts have discussed this.

when it doubt, change the propellers since they are cheap.  see if there is any difference, if not then you know it's not the props.

Hello there Oniwolf93. I am sorry for the trouble this has caused and thank you for reaching out. Are you receiving any error message on the DJI Fly application and kindly please try to replace the propellers of your DJI Mavic Mini to see if the issue will still persist? Kindly please keep us posted for further assistance. Thank you.

This. Always. Simon Templar is correct.

Not at all, nothing when landed, only while ascending and descending. i also thougth that maybe that sound is made by some air currents during the movement

Hello, no error on propeller whatsoever. Just an imu calibration reminder that disappears after a few seconds before taking off. Also did the calibration so i don't know. I'll try to change the props, maybe by touching them under a wall, i made some invisible damages

Well the Mini 1 is a noisy little beast, and the propellor note does change dramatically all the time.  Maybe yours is fine. If the screws on the props are tight and the blades aren't catching on eachother.

Screws should be fine, they rotate on themselves but i guess it's normal. This evening i should check if they are tight too, as you said, but i guess it's all about my anxiety

As others have commented - if in doubt, change the props. They are a cheap and disposable item, after all.  Don't over-tighten the screws if you do change the props.

Always use the new screws that come with the props,  they are pre coated in thread lock.
