Just ran the nitro truck, it runs great. And the on road has a stripped spur but it started right up and seemed to run great too. Ill fix that and get her runnin good. The only thing is my electric one, i used my gf's dad battery because mine was dead, and it ran good, then after i charged mine it ran literally 20 feet and would sputter, so it was dead. So i charged it again and it went a little longer but died after a minute or so. Plus it had no so great power. So i know i asked this before but what are some good batteries? what are you guys runnin? i know some guy reccomended the associated wolf pack, 4200 mah or somethin like that, they are 30 bucks, so i figured if i get two, i can get 20 bucks off a 50 dollar order. Tower sent me an e mail, so thats 40 bucks for 2 pretty good batteries. And if a charger charges at 1, 2, 4 or whatever amps, how long will it take to charge?
