I did have them a while back shortly, but sold them off because I didnt like how narrow the Phaltlines are- 'fickle' is a good way to describe my choices sometimes....
As soon as the revo platinum is released traxxas should have factory 17mm hubs available. I have the ofna 17mm adapters now and they are pretty good, but I think the factory fit ones will eliminate some of the little sloppiness the ofnas have.
