50 N1 Tail Slop

[Aerialist]

I just finished rebuilding my tail after I blew off a tail blade. There is absolutely zero slop when twisting the blades, trying to change the pitch, but if I grab the ends of the tail blades and push them toward and away from the tail boom, there is a little bit of slop. You can see the tail grips moving very slightly against the hub. Is this normal? Everything back there is brand new after the crash. The tail grip parts did come with two thrust washers, one brass and one aluminum. Should I put both thrust washers in?
