You can get them from your local hobby shop. You can look up Traxxas, losi, tamiya, or even Amazon has cheap knockoffs. But NEVER buy Walmart or target Rc’s as they are very cheap and non upgradeable. Tamiya has sets you can build yourself, put your own electric motor in, and paint your own body (that’s how pro cars come, they come clear then you paint with Lexian paint). Cool hobby. Although a cheap one can run from 150-200$ and an expensive one can cost 1000’s$.
