yes, you have to dremel like like of each wall, but trust me, if my rustler hasn't has any chasis durability issues, than i doubt that you will. i have jumped my rustler 20ft+ into the air. i have jumped over single story houses with it. i dented the motor from the chassis hitting the ground so hard that the plastic motor mount flexed enough to let the chassis inflict a huge dent. the battery tray walls do not do much for the truck, it is the ridge on the underside of the chassis that gives the support.
