DON'T SPEND $80 ON A NEW ONE WAY ASSEMBLY WHEN YOU MAY ONLY NEED TO REPLACE A DEFECTIVE ONE WAY CLUTCH BEARING!  This is an upgraded one way bearing used in the TREX 700-800 series helis as well as the early model ALEES Rush 700 and 750, Gaui X7 upgraded hub and the TSA 600 and 700 series.  Sometime after April, 2013, ALEES used a different one way bearing assembly.  Check yours before ordering.

    Should actually be called an UPGRADE vs. Replacement

    Posted by Michael Chad 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!
