Heya Sharks - I'll just answer all of your questions here, including what you asked me in your email.
It's an Associated T3, which means it's a truck. As for being a good carpet racer, I couldn't tell you... I'm not aware if anyone is running them on carpet. Might be fun, though.
The truck is not ready to run. It's a rolling chasis without electronics, so you'd still need a speed controller, motor, radio, and batteries.
Let me know if you need more information.
