Traxxas TRX-4 Sport 1/10 Scale Trail Rock Crawler (Blue)
First RC I've bought, read every review on just about every rock crawler out there. I'm probably not the best judge since it is my first RC, but just like every review on it, the servo is junk. After about an hour, my daughter hit a little piece of concrete and stripped the servo horn. Little sad I thought. And if you got any weight at all on the steers, it won't turn the tires, you got to move to get the tires to turn. But other then that, tough little truck, she beat the crap out of it, hard!! I bought it knowing I'd have to change the servo, so I can't give it a bad review. It's definitely fun and I see myself buying a couple more.

The traxxas Trx4 sport is a awesome truck it's truly ready to run with your battery. The truck is a great crawler it climbs over anything. The factory tires do a awesome job but upgrade to the proline hyrax tires and then the truck really comes alive! Then the upgrades that are available are endless and available at Amain hobbies. Traxxas sure was thinking when they were designing this truck. I would strongly recommend buying this truck it truly will amaze you! The folks at Amain are very helpful in answering questions that you may have about upgrades or anything you want to know.

A great way to get into crawling. Very happy so far no problems and a lot of fun to drive. I went this route because I did not want the 2 speed transmission or the locking diffs.You will be happy with your purchase and as always amain is first class to deal with.

Traxxas TRX-4 Sport 1/10 Scale Trail Rock Crawler (Blue)
Just getting back into the hobby after 25 years, alot has changed. The TRX-4 Sport fits the bill for a quality trail and backyard rig for me. Alot of plastic parts but it is sturdy and nicely designed. Climbs and crawls over things that I never would have thought possible for an RC truck. Very pleased with Amain Hobbies and my purchase.

Unfortunately, I have to wait to run it. Oh Traxxas, when will you start including decent electronics right out of the box. I love the trucks clearance, stance and looks, but the servo failed right out of the box (would turn one direction but not the other) and the response from Traxxas for an unused truck was to send me a gear set, so I can rebuild the servo. I recently purchased an Axial SCX10 II 2017 Jeep Wrangler (poorly glued tires) and an HPI Venture Toyota FJ (weak, but working servo) and no failures yet.
