This is the Traxxas Unlimited Desert Racer "Rigid Industries" Style UDR 6S RTR 4WD Electric Race Truck, along with TQi 2.4GHz Radio & LED Lights is Race Truck is a true to scale 4-wheel drive desert race truck. The 4-link solid rear axle design provides huge suspension travel with authentic driving dynamics. From the cantilever sway bars to the 8 GTR shocks, Traxxas has accurately reproduced a true unlimited desert race chassis in both form and function. Attention to detail captures the look and feel of Trophy Trucks and Unlimited Trick Trucks as they charge hard across the desert at full speed.

The performance of this versatile race truck is now complemented by a high-intensity light from the rugged waterproof LED lighting system. A high-voltage amplifier powers 204 individual LEDs for brilliant light while tightly regulating the voltage to eliminate flickering and dimming. The rear light bar features class lights and smart brake lights that work when brakes are applied in either direction.

Traxxas Unlimited Desert Racer UDR 6S RTR 4WD Race Truck (Rigid Industries)
While I dont typically buy RTR RC rigs, every once in a while one comes out that I just want to add to the collection, and when the UDR was released I knew I would someday get one. I also despise spending money on anything Traxxas, the UDR seemed too cool to pass up. I’ve been building and running RC vehicles for over 30 years so I know what I like in a new vehicle and what I don’t, and the UDR is a unique truck that has both cool features and some that make me wonder what Traxxas was thinking. Also, like always I chucked the stock servo in favor of real one, installing a Protek 170tbl before ever running the truck.

Its by far the most fun when running it in big open packed dirt or gravel parking lot or hard packed baseball infield although they are a bit small. Basically any surface that is hard packed enough that your tires dont dig in causing constant traction rolls but also has a bit of loose stuff on top to help slide and to throw huge roosts. It’s not too fun on dry pavement or grass, basically any surface that has a good amount of traction as the truck will just traction roll too easy once it’s going a moderate speed. Also its definitely not the vehicle to bash with or for big air. It won’t last doing stuff like that.

Overall, I think this truck is only a good rig for certain people. I would only recommend it to experienced RC people who enjoy or don’t mind spending a good amount of time doing tear down cleanings and maintenance. This truck can easily take 4 hours or more to completely break down, completely clean and reassemble, where your standard 1/10 or 1/8 buggy or truggy would take half as long. While the suspension and overall design is cool because of the scale factor, it makes accessing things like the front diff and other parts that need regular maintenance a major job. The drivetrain is overly complex and has a lot of moving parts which makes it heavy and inefficient.

The only part that right from the beginning I knew wouldn’t last was the body. It was just way too thin around the lower body mount screws and it ended up tearing around several of them after only taking a couple low speed rollovers. It had major cracks in several areas and was hardly hanging on after about 10 traction roll/ tumbles. Not very good. I opted to replace it with The ProLine Ford body which is thicker but doesn’t fit as tightly to the inner roll cage which may cause it to crack easier. Time will tell. The only other part that I had to replace was one lower front suspension arm that I broke on a bad landing from a big jump that I hit going too fast. I’ve also had to replace numerous bearings that were either seized or nearly seized which I’ve never seen before. I would have an extra set on hand for sure.

I’ve only run on 6s and the top speed is fast enough, but I can tell the 1/8 scale size motor is taxed pushing the big truck and heavy drivetrain around. I plan on upgrading to a larger can motor and esc setup that will run cooler. I don’t think 4s would be much fun unless you were limited to a small area to run in. Overall I like the truck but like any RTR or Traxxas, there are a lot of parts that I would like to upgrade if someone made them or better upgrades were available.

Traxxas Unlimited Desert Racer UDR 6S RTR 4WD Race Truck (Rigid Industries)
recently purchased the Traxxas UDR. after reading as many reviews pertaining to this kit as I could find, I decided to upgrade all the weak areas on the kit that I felt need some help. although Traxxas did an excellent job designing the truck. like all of the rc trucks currently out there, there is always room for improvement. no matter which manufacture you purchase from.

the UDR offer a great start for a real performer! it size and weight lends itself well for modification. a host of manufactures of upgrade parts for this truck allows the owner to build a tailor made truck to meet anyone's needs.
power upgrades as well as a ton of aluminum components has turn my truck into my current favorite.

I love the Traxxas TSM module! first truck I own that incorporate's this technologies. makes driving the truck at high speed not only easy, but thrilling!! with a little practice and adjustments to the TSM gains I've been able to throw the truck into any high speed turns with confidence. its a real blast!!

Amain delivered my truck on time and in great condition. I will be purchasing from Amain again

I debated on buying one of these since it came out and I finally did and it's amazing. The scale detail is phenomenal and the lighting kit is a huge plus since you don't have to do it yourself.

My only con with the whole truck is that in order to mess with the lighting control you have to remove the body which I believe is 8-10 screws, which isn't hard- just a pain.

Traxxas Unlimited Desert Racer UDR 6S RTR 4WD Race Truck (Rigid Industries)
The Scale Detail is incredible and the LED light bars front and back that now come stock is really nice. Good move by Traxxas!

We don't have a ton of time on the truck just yet, but so far so good. Totally recommend this pro scale truck to anyone who loves off road racing and loves the hobby of RC. The suspension action and handling is so realistic.
