The process for improvements for this Rev4 version is documented on this web page.

Replacement Rhino-Track Hubs March 17, 2016
Reviewer: Michael Bowman from Mars Hill, NC United States  
Although the original hubs lasted only 2 or 3 matches (at FRC events), none of the replacements have failed to date.
