Exploring the TRX-4 Family: Traxxas Mini to Full-Size Crawlers

As we expand the Scale & Motion RC section, it makes sense to highlight the Traxxas TRX‑4 lineup, a landmark in crawling engineering. Whether you're just starting with the compact TRX‑4M (1:18 scale) or diving into the rugged full-size TRX‑4 (1:10 scale), Traxxas has made sure there’s a capable crawler for every enthusiast.

TRX-4 Series: Features Shared Across Models

Though available in different scales, the TRX‑4 family shares key innovative features:

Portal Axles with Locking Differentials – Raise clearance and boost crawling control.
2-Speed High/Low Transmission – Offers versatility between torque-intensive crawling and faster progression
Durable C-channel Chassis & 4-link Suspension – Ensures lasting performance in both indoor and outdoor terrains.
Waterproof Electronics & Clipless Bodies – Designed for durability and easy maintenance.

The TRX-4 vs. the TRX-4M: Which One Fits You?

Feature	TRX-4 (1:10)	TRX-4M (1:18)
Scale	Larger, rugged trail-crawler	Compact and agile crawler
Best For	Outdoor trails, scale realism	Indoor or outdoor smaller courses, limited spaces
Portability	Bulky, harder to transport	Smaller, easier to carry
Performance	Heavy-duty, high torque	Nimble, fun, beginner-friendly
Customization	Extensive aftermarket parts	Smaller aftermarket scene

The TRX-4M truly mirrors the TRX‑4’s core functionality in a more compact form—ideal for tight spaces or beginners.

Why Traxxas TRX-4 Crawler Series Stands Out

Rich Feature Set – First in its segment with portal axles, high/low gearing, and locking diffs.
Versatility – From 1:18 mini-crawlers to full-size trail beasts, there’s something for every preference.
Upgradeable and Repairable – Stock parts are robust, with plenty of RC shops offering upgrades.
Broad Body Options – Choose from Defender, Bronco, Blazer, K10—and more for both scales.

Final Thoughts

The TRX-4 series offers a seamless progression into crawling—from the manageable TRX-4M to the powerful TRX-4 scale trail machines. Whether you’re tight on space, new to RC, or chasing top-tier trail performance, there's a Traxxas TRX crawler built for your adventure.
