When it comes to off-road RC trucks, the Traxxas UDR has long been considered the best in its class. However, with the release of the Losi Baja Rey 2.0, it’s time to ask the question: is the Traxxas UDR still the best option out there?

The Br2 Suspension: Skimming on the Surface

The Losi Baja Rey 2.0 (br2) features a suspension setup that is tuned slightly heavier compared to the UDR. This means it has a slower action and slower reaction, using less travel for ordinary surface chop. While this may sound good in theory, some enthusiasts find that the br2 suspension feels a little numb as the truck skims on the surface.

On the other hand, the UDR’s suspension is designed to provide the best of both worlds. It allows for skimming on the surface while still being able to handle jumps. The suspension setup of the UDR strikes a better balance, offering a more responsive and engaging driving experience.

The Ride Height: Sprung Suspension vs Half Sprung

One noticeable difference between the two trucks is the ride height. The br2 sits higher relative to the UDR, giving it a half-sprung feel. This results in more body roll and a rocking motion as the truck navigates through obstacles. This can be both a pro and a con, as it provides a more realistic experience but also makes it prone to traction roll when breaking or accelerating.

In comparison, the UDR’s lower suspension height minimizes the dramatic rocking motion. It still rocks around, but it is less pronounced due to its lower center of gravity. This results in less sway and less tendency to traction roll.

Sway Bars: A Difference in Approach

Another factor to consider is the sway bars present in the suspensions of both trucks. The UDR features both a front and rear sway bar, while the br2 only has a rear sway bar.

The UDR’s rear sway bar is connected to the top of the rear axle, mimicking a more realistic setup. On the other hand, the br2’s sway bar connects to the front of the trailing arm, which is less effective and allows for more flexing. This gives an advantage to the UDR’s rear suspension, providing better stability and control.

Suspension Limiter Straps: Protecting the Shocks

Both trucks feature suspension limiter straps that connect the rear axle to the cage during a full droop drop. These straps serve to protect the shocks from potential damage. Not only do they provide practical functionality, but they also add to the overall aesthetic appeal of the trucks.

The Verdict: Is the Traxxas UDR Still the Best?

After carefully comparing the Traxxas UDR and the Losi Baja Rey 2.0, it’s clear that both trucks have their strengths and weaknesses. The UDR offers a more balanced and responsive suspension setup, with better sway bar placement and less tendency to traction roll. On the other hand, the br2 provides a more realistic ride height and a distinct skimming experience.

Ultimately, the choice between the two will depend on your personal preferences and what

The Performance Differences: Locked Axle vs. Oil Filled Differential

When it comes to performance, both the Traxxas UDR and Losi Baja Rey 2.0 have their unique strengths. The UDR comes with a locked rear axle, while the Baja Rey 2.0 (BR2) uses an oil-filled differential. This difference in differential types has a significant impact on the traction generated by these trucks.

The BR2’s oil-filled differential provides it with more traction compared to the UDR’s locked diff. This means that on high traction surfaces like the street, the BR2 tends to traction roll more frequently. On the other hand, the UDR performs better on low traction surfaces such as dirt, as it doesn’t slide around as easily. Both trucks, however, have no trouble sliding around when desired.

Moreover, the locked diff in the UDR creates a sensation of the rear of the truck being led by the front end. Without utilizing a little assistance from TSM (Traxxas Stability Management), the UDR can easily spin out. In contrast, the BR2 feels more balanced in this aspect, making it easier to drive without the need for ABC stability.

The Tort Twist: Cornering and Steering Differences

One crucial aspect of these trucks’ performance is the presence of torque twist. The BR2 exhibits significant torque twists under power, as evidenced by driving on three wheels during speed runs. When accelerating with sufficient traction, the front left wheel tends to lift up. While this aspect emulates realism seen in actual stadium truck racing, it affects cornering, making left turns better than right turns under power. Additionally, torque twist pulls or yanks the steering to the left, requiring counter-steering. Adding a front sway bar to the BR2 can help reduce torque twist, although out of the box, it grips, rips, and twists.

In contrast, the UDR effectively eliminates torque twist as it features a locked rear axle, full sway bar support, and harder compound tires. These elements result in minimal chassis flex, generating better traction. This significant difference in torque twist handling sets the UDR apart from the BR2.

The Verdict: Is the Traxxas UDR Still the Best?

Considering the performance differences discussed, it is difficult to definitively declare a clear winner between the Traxxas UDR and Losi Baja Rey 2.0. Each truck excels in its specific areas, with the UDR offering better performance on low traction surfaces and eliminating torque twist, while the BR2 generates impressive traction with its oil-filled differential.

Ultimately, the choice between these two trucks comes down to personal preference and intended usage. If you primarily drive on low traction surfaces and want to avoid the challenges of torque twist, the UDR may be the better option. However, if you prioritize high traction performance and are willing to manage torque twist, the BR2 provides a thrilling driving experience.

In the end, regardless of which truck you choose, both the Traxxas UDR and Losi Baja Rey 2.0 offer an absolute blast when it comes to driving and experiencing the thrill of RC truck racing.
