Hi, I don't know if this is normal or not, but maybe a fellow Air 2S owner can confirm. I had a small crash, no visible damage at all except for a broken propeller (now replaced). Checked out the drone and noticed the AF is making a lot of noise. Video looks fine on the drone but I'm a little OCD about my expensive purchase. I have DJI care and don't know if this is worthy or a replacement or not

Here is a video showing the sound:

I would send the drone to the service for a check. IMHO it’s worth to spend some money on it and avoid nasty surprises.
