Experience true desert truck dynamics with the Traxxas UDR Pro-Scale With Lights. Combining Pro-Scale realism with brutal 6s performance, this Unlimited Desert Racer is engineered like the full-size trucks it replicates. A 4-link solid rear axle, cantilever sway bars and eight GTR shocks work together to deliver huge suspension travel and authentic handling on rough terrain.

Powered by the Velineon VXL-6s system and a 2200kV brushless motor, the UDR delivers up to 50+ mph on 6s LiPo. An ultra-tough drivetrain and Traxxas Stability Management (TSM) help put the power down with confidence, while the integrated high-voltage lighting system enhances realism for immersive driving at dusk or dawn. Control comes via the TQi 2-channel radio and 6533 TSM receiver, with a durable 2075X metal gear servo handling steering duties.

This Traxxas UDR Pro-Scale With Lights, part number TRX85086-4, faithfully captures the stance and detail of modern Trophy Trucks and Unlimited Trick Trucks, from its large Pro-Scale body and replica components to pre-glued BFGoodrich KR3 tyres and dual-diameter wheels.

What is the largest single 4s battery that can fit in it with a xt90 plug
Aiden / 7th December 2025

They do not do a single 4s to use with this is would be 2x 2s lipos these are the biggest TRX2869X

Steve @ Wheelspin Models
Is there any non-traxxas battery's that could fit on this with a charger? Looking for max run time on duel 3s batterys
Aiden / 4th December 2025

Yes these ones (x2)O-GTC3S5000-60X9

with this adaptor (x2) OL-3285

and this charger ET0202

and this lead ET02649

Steve @ Wheelspin Models
Hi, with the Traxxas 7600mAh 2s batteries, is run time significantly longer than 3s? Not worried about speed.
Liam Sinclair / 27th April 2025

The runtime is the mah not the voltage .

Steve @ Wheelspin Models
Hi, is there a way to change the connection so that you can run different batteries that aren't traxxas batteries. ?
Alfie Turton / 26th September 2024

The only thing you could do is use adaptors. We would never advise re-soldering the connector as it will end the warranty on the car.

Rich @ Wheelspin Models
Hi can you get a stainless steel screw kit for this
Matthew Ruddle / 24th April 2023

I'm sorry we do not sell a stainless screw kit for this.

Steve @ Wheelspin Models
Hello does the udr have oil filled shocks in all 8 or just the 4 with springs on?
Matthew Ruddle / 17th April 2023

This car has oil in all of the shocks 

Si @ Wheelspin Models
Hi. Are the wheels on the back actually usable or just for display?
Kaiull / 9th December 2022

Yes these are a complete usable wheel and tyre.

Si @ Wheelspin Models
hi is there a car out there without wheel in the back
Richard / 22nd June 2022

These only come with a wheel on the back.

Steve W @ Wheelspin Models
Hi, what run time will I get from this racer using dual 3s 5000mah 11.1v batteries ?
Rob Archer / 23rd April 2022
