Also if you get a brushless system MJX hyper go they're considerably faster. You will have so much more fun when you put a 3S battery to it. By the way you can hook a 3S battery up to your brushed truck that you have now You just have to watch the heat give it some breaks so it don't overheat. Run it for a little bit let it rest You can do that all day as long as it don't get too hot. And you'll enjoy the 3S guaranteed.😊
