Thanks BuzzBomber and rapr! the velcro thing makes perfect sense! I'm gonna try that. I have to get some more velcro though.

I'm still going to order the battery box to see how that works out. I like that it's closed because it'll offer more insulation to the batt from the aluminum. that's how I burnt up a servo wire once, trying to bolt it to the chassis to keep it from hanging, and partly stripped it... the only drawback to this chassis is the short hazard if your not careful!
