dont worry, im gonna go for a internal duel cell pretty soon...with my shen clone using 2 50mah batts just to see how it works cause it'll be my first time doing it. But then i would also need a soldering iron...10 bux only and its made by Mastercraft...good stuff.
Then after that i'll see which chassis i'll do the internal duel cell on with my 2 150mah batts.
im gonna work sooo much in the summer....$$$$
