I was planning on using the stock tanks but now that you mention it, that's a great idea for freeing up some cab space. The ESC's are small. ( same as the ones in my loader as a matter of fact ) I think it would be money well spent to buy some custom tanks. Thanks!
I'm on the rc4wd site right now. Going to pull the trigger and order this light system. It's small and has some decent options and cheap to buy.

I think the charge port is a great idea to minimize opening the truck all the time but when you want to play for more than a charge cycle it's nice to throw a fresh one in, throw the old on charge and keep on trucking!
