I haven't used it in years. I took it out, and it started right up. Servos worked, car drives no issues.  It's the roto start with the older desirable engine. The chasis is the modern chassis with the X in it. I don't know much about these, but it comes as pictured. Sold as is because of the nature of the hobby.  There is plenty of power, starts and runs well. Comes with what is pictured. No controller.
