Thanks for the reply. I am going to get the hardened HPI in a couple of days. LHS has an order coming in. I did pick up a set of Kyosho gears to play with set up etc. They seem to be a little better design. They seem to go together more smoothly.

Question:

What would cause it to bind when I tighten the ring to the cup? Shimming would only make it tighter right?

Thanks!
