It also supports real-time telemetry, enhancing control and diagnostics. The Velineon motor includes a 4-pole design, a robust five millimeter output shaft, and a finned can for improved heat dissipation, ensuring reliable performance under demanding conditions.

Pro-Scale™ Body

The Traxxas UDR boasts a large Pro Scale® body packed with highly detailed replica parts that elevate realism and durability. Its heavy-duty truck body mounts secure to a functional tube frame chassis modeled after full-size trophy trucks. The detailed interior features lifelike driver figures, while scale components like brake calipers, seventeen millimeter wheel hubs, dual working spare tires, a spare driveshaft, and accessories such as fire extinguishers, shock reservoirs, a jack, and tools enhance its authentic appearance. Realistic side plates complete the rugged, true-to-life design, making it a standout in both performance and visual appeal.

Up front, it includes steel CV driveshafts with six millimeter stub axles, an oil-filled limited-slip differential, and a heavy-duty splined driveshaft.

nathan boles Verified Owner Wednesday, Jul 2 2025 (3 months ago) Traxxas Unlimited Desert Racer UDR 6S RTR 4WD Race Truck (Fox) Showed up the day it said it would. Beautiful truck (orange is my favorite color) runs good. Held up at the skate park and hasn’t failed to put a smile on my face!! 3 customers found this review helpful. Chuck Chinn Verified Owner Thursday, Aug 7 2025 (7 weeks ago) Traxxas Unlimited Desert Racer UDR 6S RTR 4WD Race Truck (Fox) Not so much a review of the Traxxas UDR but of AMain Hobbies. I received my UDR in the sealed factory box inside of a factory sealed box. When I unboxed it, I noticed a very small black part lying on the dining room table. “HMMM, better figure out where that goes.” When I turned it over and spun one of the front wheels, the “dog bone” fell out. “Oh goodie!”. I called AMain the next day and spoke to Wally. He stayed with me while I explained what I though was wrong. After we determined that there was no further damage to the stub axel socket, and that the part was left out by the factory, he offered to have me send the truck back or he would send me the missing pin and bloc set. I have built and modified a “few” RC cars and trucks in my time, so I opted for the parts.
Now, this is where it gets kool. Wally FedEx expedited the parts to me in the hopes that they would be here in a few days. They arrived before noon the following day as I’m “just” up the road in Central Oregon. I’m a happy camper and very satisfied customer. I will continue to deal with AMain in the future. Oh … and the truck runs fine. View all reviews
