just a warning. i have done alot of work to my minix. it was not nearly as easy to uprgrade than the xmod or miniz but even stock the xmod will beat a mr-02 only if the set you get comes with 5 or 6 cells. if i were to get another one i would get it from here
(free advertise) it comes with bearings
i think the only reason i would even touch a miniz is just to have it as a static model cause they are pretty to look at ;p with the exception of my mini-z overland, i love that thing
