tail-rotor blade grip question

[buster1]

I am flying the Logo 5003D and notice a little back and forth play in the tail rotor blade grips - I have not checked it in a while and recently noticed this after about 10-15 flights. Is this normal?

This heli. flys great - I am very happy with the 500.

I also noticed this after about 5 flights.

Its not need to worry as the centrifical force when the spins will keep of straight and firm against the thrust bearings
