still had it in my box.. you can see the difference.. now I don't have to worry about one breaking.
and fyi don't care if you ran a 6.5 motor... I have seen them break with a stock motor and 5 turn hot mods... just because you didn't break one doesn't mean they wont break.. I broke both mine on carpet so the surface doesn't matter.. or maybe it does as carpet fibers do get in there over a 6 minute race and maybe that's what makes the stock ones break once in a while.
