Hi guys I just notice that the helicopter has a different sound to it so I landed it and I found some up and down play on the shaft and I'm not sure if this is normal or not, can someone please help me with this, thanks

I think 1 or 2 MM is what I have on a Hyperion 1100kv motor, Have been told it is OK.

If there is vertical play on the shaft, you have a good chance of wearing the shaft or inner bearing races. I take all the play out till the retaining clip is against the wavy washer. Most of my Scorpion motors came the way I just described.

i assume that you add a shim to remove the vertical play.

No shim added, just take out the set screws, put the fan end down on a piece of wood(drilled out for shaft clearance)and tap on the pinion end of the shaft till the retaining clip is seated against the wavy washer. Loctite set screws and reset them.
