TRX-4 vs SCX10.
The hobby's biggest rivalry, settled honestly.
Every crawler forum has this thread, and it never dies: Traxxas TRX-4 or Axial SCX10? They're the two dominant 1/10 platforms, both excellent, both with massive aftermarkets — and they take genuinely different approaches to going slow over rocks. Here's the honest breakdown, with the real prices you'd pay today.
Price: the SCX10 III starts cheaper
The entry prices tell the story. The Axial SCX10 III Base Camp is $339.99 at Horizon Hobby — the cheapest way into either platform. The Traxxas TRX-4 Pathfinder is $499.95 at AMain (a genuine $50 under its $549.95 MAP), and the Bronco version runs $549.95. That's roughly a $160 gap at the entry level.
But the gap narrows as you climb: a loaded SCX10 III (Motobilt Gladiator, $499.99) costs the same as the TRX-4. The real question isn't which is cheaper — it's whether the TRX-4's extra features are worth the premium to you.
Features: the TRX-4 brings more tricks
This is the TRX-4's home turf. Out of the box it gives you three things the SCX10 III doesn't:
Portal axles
The axle tubes sit above the wheel centers, buying meaningful ground clearance without lifting the chassis. On rocky terrain this is a real, measurable advantage — the truck simply high-centers less.
Two-speed transmission
Low gear for technical crawling, high gear for trailing between obstacles. One truck that does both jobs well, shifted from the transmitter.
Remote locking differentials
Lock and unlock the front and rear diffs independently from the radio. Open diffs for tight, natural turning; locked diffs for maximum traction. It's the kind of feature that feels like cheating the first time you use it.
The SCX10 III counters with simplicity: straight axles, a proven single-speed transmission, and less to learn, adjust, and maintain. There's real value in that — fewer features means fewer things to break and a lower center of gravity.
Scale realism: the SCX10 III's edge
Axial built its name on scale looks, and the SCX10 III carries that torch — licensed bodies (Jeep, Ford, Toyota), detailed interiors on some trims, and proportions that look right. The Coyote ($349.99) and the Motobilt Gladiator ($499.99) are genuinely handsome trucks. The TRX-4's bodies are good — the Bronco and Pathfinder are sharp — but Axial's scale game is deeper, with more licensed options across the lineup.
If the truck spending most of its time on a shelf needs to look amazing, Axial gets the nod. If it's a tool for conquering rocks, the TRX-4's feature list talks louder.
Aftermarket: it's a tie (and that's the point)
Here's the thing most forum arguments miss: both platforms have elite aftermarket support. Brass, tires, bodies, chassis conversions, portal weights, link sets — whatever you want exists for both, from dozens of manufacturers. Our SCX10 parts page and TRX-4 parts page track verified deals for each, and both are deep.
This is also why both platforms anchor our fitment guide. Buy either one and you'll never lack for upgrade options — which means the decision comes down to features and feel, not parts availability.
The verdict
Buy the TRX-4 if…
You want the most capability out of the box, you'll use the two-speed and diff locks, and the $500 budget works. The Pathfinder at $499.95 (on sale from $549.95) is a lot of engineered truck for the money.
Buy the SCX10 III if…
You prefer simplicity and scale realism, you want the lowest entry price (Base Camp at $339.99), or you'd rather spend the $160 difference on tires, brass, and a better servo — which, honestly, is where the performance lives anyway.
Either way, check the RTR trucks page for current verified prices — street prices move with sales, and the best deal today might be whichever platform just went on sale.
TRX-4 vs SCX10 FAQ
Which is better, TRX-4 or SCX10 III?
Neither is objectively better — they're different answers to the same question. The TRX-4 brings portal axles, a two-speed transmission, and remote locking differentials: more features and ground clearance out of the box. The SCX10 III leans toward scale realism, mechanical simplicity, and a lower price of entry (Base Camp at $339.99 vs TRX-4 at $499.95+). Choose by which feature set matches how you crawl.
Is the TRX-4 worth the extra money over the SCX10 III Base Camp?
The price gap is real: about $160 between the SCX10 III Base Camp ($339.99) and the TRX-4 Pathfinder ($499.95 on sale). For that you get portal axles, two-speed transmission, and remote diff locks — features that would cost far more than $160 to add aftermarket. If you'll use those features, the TRX-4 is worth it. If you want a simple, capable truck and plan to upgrade selectively, the Base Camp keeps $160 in your pocket.
Which has better aftermarket support?
Both are elite — the SCX10 and TRX-4 have the two largest aftermarkets in crawling. You'll never want for brass, tires, bodies, or chassis options on either platform. This is genuinely not a deciding factor; both will have parts support for a decade or more.
Can the SCX10 III keep up with the TRX-4 on the rocks?
With the right tires and setup, absolutely. The TRX-4's portal axles give it a ground-clearance edge stock-vs-stock, but an SCX10 III on good tires with proper weight bias is every bit as capable on most terrain. Driver skill and tire choice matter far more than the badge on the body.
Which is better for a beginner?
The SCX10 III Base Camp at $339.99 is the easier recommendation for most beginners — lower price, simpler mechanics, and plenty capable. The TRX-4's extra features are genuinely useful, but they also add complexity (more to learn, more to maintain). That said, if the budget stretches to $500 and you want the most truck for the money out of the box, the TRX-4 Pathfinder at $499.95 is a lot of machine.
