I've noticed that the propellers in my H have quite a bit of play. For some reason, the "A" props (black) noticeably more than the 'B' props. The most loose one probably turns around 5° freely around the spindle.
I don't think this affects flight - the motor torque must keep them tightly against the spindles - but since new propeller blades sit quite tight on the same spindles, something must be wearing down. Are you supposed to replace these at some point as a preventive measure, even if they don't show any other damage?
