Prop play?

[island2]

On my P4P+, I noticed when putting on the quick release props that there is a slight bit of difference between props. Holding the motor with my left forefinger and thumb, and putting on the prop with my right hand, after it's pressed, turned, and released to lock it on, I quickly and lightly checked to be sure it's on by just seeing if it has any turn (without pressing) and noticed that 1 prop has no play at all relative to the motor, one had a tiny, tiny bit of play, and 2 have a bit more play.

I don't see any looseness of the spring hub on the motor when the props aren't on.

Is this normal to have a slight bit of play due to the manufacturing tolerance of the plastic props, or something I should check more closely?

I would check a bit more closely to be sure...
I have seen both play from the hubs to the motors, and from the hubs to the props, as well as props that would not fully spring up into position on the hub when they were new due to "tolerances".

Hub to motor can seem ok at first check, but if you hold the motor and hub tightly and twist fairly hard you may find there is a very slight movement, most have fixed that by changing to another set of hub screws.
With my new p4p the black prop hubs were both loose right out of the box. I was able to fix them with some "precision" torquing of the screws, obviously the "tolerance" on the shouldering of some of the prop hub screws was a little long, and I re-check them often because after a day's flying there could be movement again. It is now a part of my preflight check and if they ever get loose again I will put on a set of new prop screws as I now have a full hub/spring/screws replacement set.

For prop to hub, again with this p4p right out of the box, I had props that did not fully rise into position due to "tolerances". When I would put the props on I could feel a slight difference in each one but it took me a few flights to figure out what was happening. Once I figured it out I would simply pull up on the prop to fully seat it until it "broke in" enough that the spring pressure was able to seat it on its own.

As far as some slight movement from prop to hub, it's no biggy and quite common with different batches of DJI props I have purchased at various times, but I would make sure that the motor to hub connection is solid first.

Thanks very much. Will give it a good examination tomorrow. Appreciated.
