Just to avoid confusion I am assuming you are talking about Part No 29 in the manual "BLH2020 Tail rotor hub set". I was looking at this the other day when I replaced the tail rotor because I noticed what I thought was too much motor shaft end float (around 1mm). I slackened the two allen screws and tried to push the hub further onto the motor shaft but it wouldn't go on further so I left it. I assume you can push yours full up against the motor. Ideally I would say that this has to be set up with minimal end float but no friction on the motor. Perhaps we should find some small washers to act as shims to set up a sensible amount of end float on the motor. I think 1-2mm is too much. Incidentally I check both motors after each flight and neither of mine get hot, just warm to the touch.
