This is the Traxxas Unlimited Desert Racer "Fox" 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 (Fox)
Great pro scale well built model. This is not a toy its very reliable and takes skill to maneuver. It will crash and roll over if you operate the model like a normal truck or other traxxas models. Its very fast and has the ability to tackle any kind of terrain surface. On pavement its very tippy and catches and flips over very easily if you do not get on the throttle and swing the rear end around like a desert racer truck woukd do. Its fun and good on battery wether you run 4s to 6s its just as good on 4s.

Truck is Great! All the right stuff but ordered accessories to make it just a little better and realistic. It may end up a little heavier but still perform great. These trucks are so realistic when making jumps.

This truck is fantastic. The videos on YouTube comparing it to the Mojave etc are fun, but this truck really isn’t a “basher”.

If you want a scale truck - solid rear axle - long trailing arms - realistic action etc, then you should grab this truck!

This thing REALLY utilizes the locked rear axle to maintain traction during fast acceleration.

If you just want a fun larger scale short course style truck to rip around with and ramp etc then I’d point you towards the Mojave. But for scale realism and tons of power out of the box, this is a fantastic truck!

I loved this truck so much I bought another one. If you want the ultimate in scale realism of a desert racing Trophy truck this is the one. I also own a Mojave, which is a total blast, but the UDR behaves and looks just like a real truck. The electronics are actually really great from the go. The steering servo is fine, and all my stock gear is still running strong for over two years now. There are a few things to upgrade over time as they wear out, but all-in-all, the UDR is hands down my favorite truck.

This truck is amazing and goes into every detail for the scale look, but if your planning on getting one its well worth it but its built for SCALE driving and not built for big jumps on the track unlike buggies which are made for it. Don't get me wrong this thing can take one hell of a beating and for sure go on the track but when jumping, because of it's weight and the way its built is has a tendency to roll over if you land the wrong way really easily and has a tendency to nose dive or slap the back end on big jumps on landings which is what its not made to do but it sure is capable. Then one last thing to consider is that sometimes you'll hit a little dip or turn to fast and expect to roll over maybe once or flip in the air, but with this truck you end up doing barrel roll after barrel roll or endowing over and over several times which is exciting to watch, so expect to flip, roll, or endow more times than usual on the smallest accidents, but don't worry as long as you weren't hauling ass while you flipped the truck will be fine even though the crash will not make it look fine. Overall this truck is great and is made for a person who likes to drive Scale and have that scale experience with the wight of the truck. (BTW: this truck only takes long and skinny traxxas connector capable 2&3 cell lipos, no short and fat lipos because you can't stack the short and fat ones together only the long and skinny ones can stack nicely and fit into the battery compartment. And if you know how to handle two 3 cells, get it because its much more fun with two 3 cells than two 2-cells but if your just starting out i recommend two 2 cells so you have a less likely chance of crashing your vehicle.)

This truck is bad-to-the-bone. It's an extreme rc and easily one of the most scale rides ever made. On 6s it's got the Devil in it.

Traxxas Unlimited Desert Racer UDR 6S RTR 4WD Race Truck (Fox)
I am very pleased with this model it was purchased for my grandson because of its durability and driver aids. This allows younger drivers or beginners with supervision to safely use this Rc Truck. I like that there are a lot of support products for for repairs or upgrades, it is however not for the beginners due to the fact that the directions or the parts list it’s not laid out like a model that you build, unlike a traditional nitro or electric kit where you can go step-by-step on how assemble it. My biggest complaint is that for the money you should have detailed directions for this Rc truck for purpose of repair and operation. This would allow most people with the basic tools to really enjoy this Rc. The quality of construction and materials used is very good, there are some items that could use improved quality control or better quality materials that would improve the overall build.

The directions or instructions that you get with this model RC is its biggest Problem, they are not very thorough or very detailed and that’s why I believe this is for someone with experience in the Rc Hobby. I had to call the manufacture because I was unable to turn off the truck with the speed controller and I was unable to program the truck for my grandson. The current model of this truck the batteries have to be unplugged to get the electronic speed controller to turn off that is because there is a drain on the batteries because of the previous firmware or programming so they decided to just have Us unplug the battery that is Not Ok for an $800.00 Rc vehicle. They send a reminder in the battery storage area stating that you should puncture the tires so that dirt that gets trapped in the tire can be thrown off during normal operation, at the very least each update or change to any of the operating features for this vehicle they should have paperwork that would explain what to expect when purchasing this vehicle for proper operation.

Last but not least I have decades of experience starting from Estes rockets and hand built Rc planes to our current RTR variety of Rc vehicles. This by far is the most accurate most detailed RTR RC truck that you can buy on the market. There is no other truck that you can buy that shows the kind of detail and or that has the ability to upgrade that this vehicle has, if only I had something like this growing up! This by far with a few exceptions is probably the best way to introduce a young man or young lady into Rc modeling. The only thing better would be to build this as a kit so that the builder would understand how everything functions and operates in My Humble Opinion.
