I just noticed that one of my motors has some side to side play on the bell. Is there any way to fix this? If not, can someone recommend another 960KV motor that doesn't have this problem? WHen I first ordered my E310 propulstion set, I had to send it back as 2 of the 4 motors were like this out of the box. I've never had a crash and now I notice that one of the motors seems lose. What causes this?

Hi Joey, could you upload some pictures of the motor issue? We'd like to check the exact status and help you out.

This is the best I can do. See the space towards the bottom of the motor? The other motors don't have that much space there and when the prop is on there is side to side play.

I was considering purchasing these motors as replacements (Available on Amazon) but not sure if they work with the 420S ESC's I currently have.

Can you tell me if they will work and if they are worse or better motors. Not sure where they fall in the product lineup.
