They require maitenance, it just depends where you drive it. Let's just say your plain everyday street not much cleaning just clean the wheels when your done. Offroad like on dirt, try to wipe it off the suspension and arms. If you plan to drive it on mud, prepare for some heavy cleaning because I drove mine once in some mud and did I regret it

I'm just saying it through how I've experienced it. Overall great fun and I second that it's "very durable". On a 6 cell 20mph and on a 7cell 24 mph. These speeds were radared by Traxxas themselves. If you have anymore questions you could go to the official Traxxas boards at
