I have a Traxxas TRX-4 Defender that has been sitting on the shelf most if its lift. It has been run, but VERY little. I have tried to take detailed pictures. There are scratches on the body, lower links and rock sliders, but the truck is in fantastic shape. The only reason we are selling it is to make room for a new kiddo! 
Everything is in great working order with the the 2-speed, and lockers functioning as the should. I have only ever used a 2s on this and all my crawlers, but the ESC is 3s compatible. 
We love our TRX-4s this was a backup model. 
Please let me know if you have any questions. 
Also, this has a 2075X metal gear servo, I cant remember it that was stock or not.. so I figured I would mention it. 
Thanks for looking!
