tinybaum they wear out quicker than anything i have owned. but the buggy handles great, thats why i went to the
trouble of finding out what will work. the hyper 7 outdrives will work and eliminates the biggest gripe i have with
the matrix. zonk the matrix gets around the track so much easier than the hyper 7, its lighter and more responsive.
i just think the metal in the outdrives is too soft.
