TinyRC.com - New mods for cars

I got some sweet stuff dont with my new LED lights if anyone has heard of streetglow then you know what im talking about i have small Blue LED lights under my one car for a sweet look along with headlights and tail lights i had to get my cars cover raised a small amout to make room for my batteries once i get my new D-cam ill have the pictures up i hope but its really sweet and easy to do im mostly do my one car for looks but i will do the ocassional drag with my new 3.2 engine. im also trying to make it so my car lights up with a light on the inside but i cant get a battery to fit. i was also wondering if its okay to let the motor and my led battery to touch because ive noticed with my boat that im working on if a 9volt touchs the motor it stays attached and i dont know it thats good or not. and maybe some of you out there could help me with this i heard of this new NOS kind of kit for bit char-g their little batteries that give a 5 second boost of speed and then die out untill you recharge them. if anyone has any info on if their real or not and if they are where can i get one!
