Hi guys, I recently flew my drone indoor and my drone drifted and the propeller scratched the walls, but I grabbed the drone as quick as possible to prevent it from actually crashing it. That's when I started inspecting all the parts on my drone. I realised that one of my motor is slightly rougher than the other 3, it's not very very different in roughness, but its noticeable, I tested this by hand turning them back and forth. As you can see in the attached photo,the right, rougher motor, the space between the motor and the actual frame is smaller than the other 3. I just want to ask if anyone mavic mini owners are experiencing this as well, or is this caused by the propeller scratching the wall. I have contacted dji support, they say as long as there is no warning or error in the app should be fine. Thank you in advance for helping me. I have been thinking and worrying all night since this is my new drone and it's only a few days old.
