Ok guys help me out here. Im getting my son a used Losi XXX-S to run around in the school parking lot. I have always run Nitro trucks so I dont know squat about electrics. Not interested in milking every ounce of speed out of it but I would like to know how to maximize run times. I emailed Losi and they said 5 minutes or less with a 1800 stick pack...there has got to be a way to get more besides going to more mAh...help us out guys, thanks.
