Maximum small car chassis remote controlled. I tried to close the powerbox, engine and servo motor in the smallest space. Of course, there is no differential here, but the engine placed between the wheels transfers the drive to both. I tried the chassis with a load and no load. The drive for both wheels is always transferred evenly. Success :)
