I think cbznamstr didn't see Coolhands movies.....

Obviously...

So whats the difference with 7XL to 9XL? Does the 9XL draw less power but can take more voltage?

well, i think i remember seeing it....Well, on the item description, it recomends more cells then just 12.

@nick, right about that theory..

@ncabz, he posted the movie yesterday or today.. in his ext e-maxx thread. check it out and be amazed!

Bad thing is the batteries was run the day before. I let set over night and ran again. The batteries was far from fresh and definitely not charged up.
The 7xl and 9xl both do good. It really comes down to the run time you want. I still want to try my 9xl on more cells. I don't have the esc capible of doing it at the moment. Don't worry I Have a 7xl on the way to. I post a video of 7xl on same truck. I can give you comparsion of run time and power.
