5,000mAh Flightpower Evo20's i think, have you seen the specs on these......
I brought a 24/160 from mike, so that so be good, i really like this controller.
I was thinking of running a pair of 6s wired to give 10,000mAh but i dont know if the weight will be an issue, if so ill go with a pair of 3s wired into 6s
Nice looking truck man. I love the UE arms. Like CHC said, it depends on the diffs. Use as suggested. If you use two 6s, it will be heavier. i run 5s in mine with 8000 mah, weighs 11lbs exactly. i have the carbon top plates though. I like your front top plate..looks very nice!

I have a setup alot like yours. Mine has the alum chassis, 1950/7, 2 3s 8000mAh batteries, setback rear arms and 21/66 gearing (that would be about 16/51 for your spur gear). Esc has a fan (MGM 160/24), no heatsink or fan on the motor and everything stays cool. I am thinking about gearing it up a little higher. I see you cut off the right servo mount on your top plate.
