Motor Chirps.

[I Talos]

I recently purchased a used Phantom 3. I noticed an frequent chirp sound from one or two of the motors. I purchased 4 replacement motors and installed them and I still hear chirps.
Is this a common issue or should I investigate further? There doesn't seem to be any other flight issues with this bird.

Makes these noises with the props off ?

I'll have to check.

No chirps. Thanks for the test advice.

On my Phantom 3 Standard - I had that. No issues whatsoever with anything - it flew perfect. I've only had one P3S - so nothing I can compare it to.

Chirping can be caused by lazy props or springs. If one of my drones chirps it means...find out why before something breaks. Know a mechanic, borrow his thermo-gun and measure the temperature of the motors after a few min. Should still be cool. Hot means insulation on windings is shedding or bearings are too restrictive. Noise always means something. Its up to you to find what.
