Hey guys...
I noticed some play in my motor...I made a video showing you the issue on all 4 of the motors, turn up your speakers so you can hear the play. Maybe the bearings have to be replaced? Can I do this myself? Please let me know
Here is the video:

Hi Mount,

I have same (vertical) play you have on 3 of the 4 motors.
IMO nothing to worry about,

Hi Mount,

Thanks man, that's what I am hearing on Facebook too! I can take a deep breath now! Thank you!

Its normal.

Vertical play seems to be normal, just the shaft sliding up and down in the ball races (there are shim washers behind the retaining circlip on the bottom of the main shaft that 'should' minimise this free play, but I guess production tolerences mean some get better shimmed than others), but if you can rock it (by grasping propeller tips and lifting one, dipping the other) then not so good. I replaced the bearings in one motor because I could rock it and hear it clicking as I did so.

JMHO
