I was was doing a check of my P4P the other night.  I've had 5 flights so far.  I noticed tha one of the front plastic propeller hubs (mounted to the motor with 3 screws) seemed to be a little loose and have some play in it.  I bought a toolkit made for those screws and I tried tightening those 3 screws.  To my amazement, the screws were pretty tight and I really couldn't tighten them much at all.  The hub still has the same amount of ply in it.

While I know the hub won't come off because the screws are tight, is does anyone else have this type of play? If all 4 were like that, I might think that it's normal.  It's strange that one is like that.

Thanks.

Same issue here with 3 of 4 mounts. Screws are tight but a little side to side play.
