You cant get new motors. But even if you could you dont need to. As far as the booster goes, I dont have one so I cant give you any solid advice on it. The range with just the propo special is good enough, But they say that the booster will double it. The worst thing about these is that a tiny bit of dust or hair can totally shut down the gears until you clean them,the floor really has to be spottless for them to run good. with the special controler on max-8888, in a twelve bu twelve room the car goes to fast to even begin to steer, Im talking about speed that three siamese cats cant touch. These things are FAST!
