Traxxas TRX-4 Sport 1/10 Scale Trail Rock Crawler Assembly Kit
Already had the original TRX-4 Sport RTR crawler; but, wanted to build the kit for the experience. Excellent choice on my part because the build was very enjoyable and I learned a lot about the TRX-4 drivetrain. Traxxas did an excellent job of packaging the unassembled parts in bags and accompanied it with a flawless assembly manual that took me step-by-step through the build. And the supplied clear truck body with all its detailed attachments is so pretty for being a lightweight shell (which I prefer over the hard shell bodies). I could not be happier. Now, back to the AMain website to select a few options...LOL

I didnít buy this kit from here. I was going to but when I went to purchase it was out of stock so I found it at Rcsuperstore. This kit is very good quality and very durable! This was my second time building a crawler kit. First one was the Vattera ascender. Took me about 3.5 hours to build. 2 hours faster than it took to build the vaterra. Seems to be much better quality than the Vaterra. Great kit and turned out awesome! Big time traxxas customer and I highly recommend this kit! Oh yea the realistic headlight/taillights look really good! I ordered the headlight light kit that has working turn Signals and brake lights
