Arrma Mojave Grom vs. LaTrax Prerunner

The Arrma 1/18 scale Mojave Grom has garnered significant attention since its release. But is it a better choice compared to the classic 1/18 scale LaTrax Prerunner desert truck?

Power System

The Mojave Grom currently comes in both brushed and 3S brushless versions, while the Prerunner only offers a brushed option. This gives the Grom an edge in performance. However, the Mojave Grom includes an additional heat sink and is paired with a high-power stock 1400mAh 2S 30C LiPo. This setup not only delivers robust wattage but also withstands extended running time. In comparison, LaTrax Prerunner falls a bit short. If u want to upgrade its stock 1200mAh 6-cell NiMH to a lipo without adding a heat sink, risk burning out the motor.

BTW, Mojave Grom’s stock battery and charger are smart, which ease to use, and save your trouble. When charging, you simply plug the battery into the charger, and it starts charging automatically, without any need for presetting.

One minor drawback of the Mojave Grom is that its stock ESC and motor are 2-in-1, which means you cannot replace the receiver independently to connect another transmitter.

Chassis

Compared to the relatively weaker chassis of the LaTrax Prerunner, the Mojave Grom’s composite chassis is sturdier in construction. Besides, a standout feature is the design of its front and rear bumpers. These bumpers are longer, providing better cushioning during collisions. The rear bumper extends beyond the body, offering additional protection. If you’re considering a durable option for children to play with, the durability of the Mojave Grom is a significant factor.

Body

The LaTrax Prerunner uses clips for removing and installing the body, while the Mojave Grom features a clipless design, making it more easy. Additionally, the LaTrax Prerunner’s body sports a graffiti style, whereas the Mojave Grom has a dynamic and energetic look. Both styles have their unique appeal.

Summary

Both are excellent 1/18 scale RC desert trucks. However, LaTrax Prerunner has been around longer, and Arrma Mojave Grom has built on its strengths and addressed its weaknesses. Despite the price difference, the Mojave Grom offers several upgrades, making it a more advantageous choice, budget-friendly, high-performance, and durable. If u are new guy to the RC hobby or looking for a small-scale RC truck as a gift for a child, Mojave Grom is an excellent choice.
