  1. UPGRADE One Way Bearing 5 Star Review

    Posted by on 22nd Jul 2014

    I have used my GAUI X7.
    I think durability and better one way bearing stock

  2. Should actually be called an UPGRADE vs. Replacement 5 Star Review

    Posted by on 12th Nov 2013

    Close to 30 flights in on this part, with an extra 2000w behind it, and it didn't even notice.
    One piece cage, clean machined edges, uniform cams, locks up quick even in over-speeding the head in descent. If I ever have to replace the upgrade hub on my Gaui, I'll be putting one of these in straight away!
