if you put all your electronics in those balloons or seal them up wouldn't they get to hot. I mean the heat would have no where to go and just make everything hot, especially the batteries and the esc?

has anyone ever tried to seal the body and chassis into one, kind of like a real car, so water couldn't get up in it. If you could seal the body to the chassis somehow you could cut slits in the body to let air pass through to keep things cool. Just wondering.
