Default DFC Blade grips? Some play

I just noticed when loading up the heli, the blade grips can slide back and forth on the feathering shaft ever so slightly. Not wobbly, or anything, but if you grip both you can slide back/forth just a hair. Is this normal? If not the only thing I can figure is I missed a washer on one side?

Either you missed a washer, or you have a feathering spindle screw that is starting to back out.

What I was afraid of ^_^, only asked because I brought it to work with full set of batteries for a session right after work... was hoping to be wrong, and not have to cancel this evenings flying to tear down/rebuild the head.

Fixed.

Was missing the inner washer between the thrust bearing and blade grips. I was wondering if that was the one, because I remembered distinctly doing one of them, but couldn't recall the other side

Nice and snug now, and will still be flying this afternoon.
