Props not spinning the same

[cbrownknox]

Maybe I am just worried because I am new and I got a refurbished, but I've noticed when the device is idle one of the propellers doesn't spin as fast as the others. Is this normal?

Also, I've read holding down the throttle for 3 seconds should stop the engines, but that doesn't always work for me. After taking the following video I couldn't get the props to stop. I tried doing the both sticks in thing (CSC) and flipped it over. Any suggestions?

Sounds like you have an issue with that one. I would not try to take off until you get it checked out.

Try holding the left stick down

I was holding the stick down. When it wasn't shutting down I took this video.

Do you suggest contacting DJI?

It seems to fly okay. Of course, I don't have a reference for normal.

Honestly from watching your video I would not have thought it would fly with any stability. May be fine but I would still be suspicious.

Have you calibrated the remote?

Have you calibrated the remote?

No. I'll do that this evening when I get home.

I concur with JBR. I would not have the confidence that I personally would need. I only fly when everything appears 100%

I watched a couple videos online and they seemed to have one that was different to the others too. Does anyone else's do it here? Keep in mind on the video they are all spinning fast but one is definitely different than the others.

Here is a video of my Phantom 3 4K. One propeller seems to spin slower when on "idle".
Flyes great thought..

That looks just like mine. Cool. From an engineering standpoint I don't know why that would be. But I'm not an engineer.

Are you using Mode 2 for the sticks?

Are you using Mode 2 for the sticks?

Yes

Unless it is sitting on an absolutely perfectly level surface, it's possible that the motors are spinning slightly differently because of that. The IMU is extremely sensitive to even the slightest slant and will adjust the motors based on that even when idling.

As for the holding down the stick to shut down, do you always pull it down to the point it clicks at the bottom?

It is very possible I don't. I bet that is it.

Good news! I calibrated the remote and the IMU and everything works great. She purrs like a kitten, instead of a weed eater. Like I said earlier, I didn't have a reference for what jt should sound like. It was definitely louder before.
