Traxxas Slash 2WD or 4WD. Which is Best?

R/C models come with two-wheel drive and four-wheel drive options, just like full-size cars. For this reason, two Traxxas Slash models that are identical can actually be different. The two-wheel drive and four-wheel drive Slash versions are discussed in this article, along with the reasons for choosing one over the other and, in the end, which is the best.

Traxxas Slash 2WD vs Traxxas Slash 4x4

while we discuss two-wheel (2WD) and four-wheel drive (4x4) vehicles in the context of R/C, we are simply referring to the number of wheels that are connected to the drivetrain, spin while accelerating, and slow down when braking.

In R/C models, when we talk about a two-wheel drive model, we almost invariably mean a rear-wheel drive model, meaning that only the back wheels are powered, not the front. We won't talk about that here, but even while there are some R/C models with front-wheel drive, they are less popular and nearly always on-road vehicles.

In the realm of full-size cars, four-wheel drive is commonly referred to as all-wheel drive. However, lorries are still referred to as four-by-fours (4x4). A 4WD model, however, has all four tyres and wheels attached to the drivetrain for R/C. As a result, it is powered when accelerating and stopped when stopping.

These versions include two-wheel drive and four-wheel drive, respectively. Although they appear to be identical, they are actually somewhat different models with very varied features when you use them. When it comes to the cost of maintaining them, they are also very different.

First up is the Traxxas Slash 2WD

Like most two-wheel drive trucks, this one has a simple layout. Except for the model's back end, not much mechanically happens. Each of the rear tyres is powered by driveshafts that move the differential, which is turned by the electric motor that powers the transmission.

Next is the Traxxas Slash 4x4.

This arrangement is more intricate than the two-wheel drive. In essence, a central driveshaft is powered by a motor. Two ends of the model receive a single power source from this driveshaft. The driveshafts that power the axles are connected to the differential in the rear end. If we follow the middle driveshaft up to the front, this is a four-wheel drive, four-ball vehicle with a second differential. Additionally, the front tyres are powered by an additional set of driveshafts included with this package.

So, what does this all mean, and why should you care?

The rear tyres are pushing since the two-wheel drive variant is rear-wheel driven. The front tyres on the four-wheel drive vehicle are always pulling in addition to making. The mechanism produces a lot of traction in a push-pull scenario. This system aspires to be constantly moving. Therefore, instead of becoming stuck in extremely loose, loamy conditions, like sand and mud, or rough terrain with obstacles, the four-wheel drive vehicle will generate more traction and succeed.

With the rear wheels pushing, a two-wheel drive vehicle works flawlessly, but not always. For instance, in highly loamy muck or sand, the 2WD model does not produce the same amount of traction. Additionally, the back tyres will spin, sink, and dig holes. Regarding the brakes, the same can be said. Once more, only the rear tyres are doing the work when you try to slow down and apply the brakes on a two-wheel drive model.

With the four-wheel drive type, you can stop more quickly since all four tyres exert the same amount of effort, which increases traction. Four-wheel drive versions are, therefore, typically more controllable. However, it's not all sunshine and roses for four-wheel drive versions.

Are there cons to buying a 4WD kit over a 2WD?

Models with four-wheel drive have a lot more mechanical components that can break down. A 4x4 vehicle, for instance, has a central driveshaft, front and rear driveshafts, and a differential. Therefore, a four-wheel drive car will eventually need to repair more parts. However, with a two-wheel drive model, you only need to be concerned about the back end. Compared to the 4WD variant, the 2WD requires less maintenance because it has fewer parts.

In addition to the expense of repairs, the extra parts on the four-wheel drive type are typically heavier than those on the two-wheel drive model. The drivetrain weighs more overall and has more excellent rolling and rotational mass. Additionally, a 4WD model usually puts extra load on the system, including the drivetrain, motor, electronic speed control, and LiPo or NiMh battery. Short-course drivers with four-wheel drive frequently huff their LiPos, whereas two-wheel drive trucks don't do that as often.

Conclusion

Which is better, the Traxxas Slash 4x4 or the Traxxas Slash 2WD, in the end? Every platform has advantages and disadvantages. For example, you will have better control with the four-wheel drive version, but it will cost more upfront and put more strain on your electronics. However, if you don't mind the little loss of grip, the two-wheel drive is a terrific base that's easier to work on, will cost less to maintain, and will be less stressful and taxing on your electronics.

For comparison, we utilized the Traxxas Slash, but this is true for almost all radio control kits with two or four wheels. But with one of these amazing trucks, you can't go wrong.
