Try to stay away from 35c batteries. They will demagnetize the motor.
To be honest, I think that the truck is fast enough with the 7.4v 3200mah 20c that it comes with.
I am personally am going to run 20c, I had a rough time controlling the 35c on the track, so I think that I will have the advantage over my friend. Ithink he'll spend more time trying to controll his truck than I will. Thanks for the information though. Which 20c batteries would you recommend?? I have had a few people suggest these http://www.hobbycity.com/hobbyking/s...dProduct=10098
. I know these are cheap and probably have a chance of some of them not performing as well as the others but I think for the price it is worth a shot. Im kind of working on a budget here so I figured Id buy 4 of these so I can have a few batteries in my aresonal. Any suggestions would be cool. THANKS.
