yes indeed it was a block of wood... not only does it anchor the bumpers, my lipo dont fit in the tray so i needed a nee platform for it! i put DSM in it, and it runs amazingly!
well, its official. i no longer have the supervader... i handed it off to ben since i am getting a rustler vxl. but dont cry, i told him he has to keep it supersized, so the bumper is staying!
