Traxxas TRX-4 Sport 1/10 Scale Trail Rock Crawler (Red)
I recently bought this truck following the advice of a Hobby Town employee. Of course, yes it's a TRAXXAS, and just the name should have been enough right. But I was conflicted about what "crawler" I should buy. The Ascender F-100 was a runner up due to just looks alone. The other option was the Axial Deadbolt II. It's just the Deadbolt was ...well....Ugly! I could go on into a huge long story about how many visits it took to make a final choice, however in order to keep your intrest...SPEND IT!! BUY IT!! It's so worth every little cent. And hey, lets be honest, for the less than 400, this truck "rocks" the crawler field.

Traxxas TRX-4 Sport 1/10 Scale Trail Rock Crawler (Red)
After much research on YouTube and talking with local crawlers, I decided to buy a Traxxas TRX-4 Sport as my first crawler. While in completely stock form, I went out with a few experienced friends to our local slick rock area ("Moon Rocks") to give it a go. And it did a great job of handling some tough obstacle courses. Almost made it through the entire day without issue; but, tumbled it down a 15-20' wall to break one of the portal gears at one corner. A $6 part and 15-20 minutes fixed that. Traxxas' on-line assembly manual was very useful in doing this repair. Did find the servo to be weak for advanced crawling; so, I upgraded it. Otherwise have watched several YouTube videos showing me how to perform several upgrades. Some were no cost mods that improved performance. So, check out "TRXS-4 Sport" on YouTube. Bottom line is that I highly recommend this crawler.

Also have to give a shout about AMain. I ordered this on a Friday afternoon; and, received it on Saturday afternoon, the next day. Amazing!!!
