This is the Traxxas Unlimited Desert Racer "Traxxas" 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 (Traxxas)
The truck is very realistic in appearance and offers lots of opportunity for improving its looks with only some paint details. Its blinding fast running a pair of Traxxas 3s 5000 Batts. The torque will suprise you from a stop and will even lift the front wheels after its already rolling a few mph. Have only had it a short while so there has only been a couple of crashes but it came out with no damage. Run time for me has been a little over an hour with the batteries mentioned above of course I was taking it easy still getting used to the feel of it. Its the easiest thing to drive considering how strong it is. The TSM is amazing and makes it manageable. You can really drive it around corners with the throttle since the rear end is locked. Again the thing is a breeze to drive.
On the bad side the body is thin on the lower sides and will crack at the screw holes. This can be avoided by adding some gorilla tape on the inside. I think my one crack was there when I took it out of the box.
The firmware update I installed made it unable to turn the truck off with the switch and must now be shutoff by unplugging the Batt. I confirmed this by calling tech service. They were very helpful and nice to talk to.
In summary this is the best RC ive owned, Ive got 3 others, Jato slayer and trx4 Bronco. But I havent had it long so hopefully it will hold up. Its a joy to look at and to drive, soaks up bumps and jumps like a real desert racer. You wont regret the purchase although it is expensive.

BEAUTIFUL TRUCK! Very scale. Led lights are very bright! You can use Traxxas Link App on a phone to control led lights to turn off and on which is really awesome. Without Traxxas Link App, you can press button to turn on light inside front of hood.
