Is a subtle rattle normal for a Tello when flying?
I only have a few hours on mine and notice a subtle rattle while it is flying.
Maybe it is typical of brushless motors? Anyone else's make the same rattling sound?
To me it sounds like one of the motors, but I can't quite localize where the rattle is coming from.
I hope one of the motors isn't already wearing out ... :(

Here's a video. I had to wear headphones to hear the rattling separate from the buzzing in the video's audio:

I can't hear any unnormal tones. It sounds like my Tello.
Do you see any vibrations on the video?

A rattle could be an indication of bent shafts, or a broken prop. Something that causes bad vibrations

So far I fortunately haven't had any indications of bad vibrations, just that rattling sound. It seems to fly normally and the video looks fine, no jello.
All 4 shafts seem to have the same amount of up/down play/movement and when I spin them by hand, I don't see an obvious indication of a bent shaft.

Does anyone else have a close up video with clear audio of their Tello for me to compare? :)
