ive got a ton of carbon fiber in my garage, hit me up if you ant a little piece to make one for yourself

rc monster makes a battery tray that works perfect, thats the one i use, it bolts through the chassis with 2 screws, and then velcro holds the battery to the tray

double sided sticky tape, the one with red backing (seems to be stronger then all others ive used...) i can lift the whole buggy by the esc, its supppper stong!!
