The best Traxxas crawlers
Crawling is the quiet half of this hobby: walking pace, no space needed, and almost nothing breaks. Traxxas makes two of them, and the small one is the surprise.

A rock crawler is not a slow version of a fast car — it is a different hobby. The challenge is picking a line over an obstacle, not carrying speed through a corner, and the reward is that it works indoors, needs almost no space and rarely breaks anything. Traxxas builds two: the 1/18 TRX-4M and the 1/10 TRX-4 Sport.
Buy the TRX-4M. It is eleven inches long, has waterproof electronics and LED lights, and — unusually for the brand — includes a 750mAh LiPo and a USB charger. The TRX-4 Sport is the better machine on real rock, but it is twice the size, needs a battery and charger, and wants terrain to be worth owning.

#1 · Crawling, complete in box
Traxxas TRX-4M
The small Traxxas crawler that arrives complete: battery, charger, waterproof electronics and a licensed body.
9.0/10our score for this use
A 1/18 scale trail crawler eleven inches long, built on a steel ladder frame with solid axles and a four-link suspension — the layout of a real truck, shrunk. Traxxas fits its waterproof ECM-2.5 module with Sport, Trail and Crawl modes, and the box includes a 7.4 volt 750mAh LiPo and a 2-amp USB charger, so nothing else is needed on the day.
- Size:
- 1/18 (11 inches long)
- Drive:
- Solid-axle 4WD
- Motor:
- brushed motor
What it does well
- Battery and USB charger are in the box, which almost nothing else in the Traxxas range can say
- Waterproof electronics and LED lights, so wet grass and after-dark driving are both fine
- Small enough for a living room, a rockery or a stack of books — no field required
What it does badly
- Crawlers are slow by design. If the recipient wants speed, this is the wrong shape entirely
- The 750mAh pack is small; a second battery is the first thing most owners buy
- The licensed bodies are ABS plastic and will scuff on rock

#2 · A full-size trail rig
Traxxas TRX-4 Sport
The 1/10 crawler for someone who wants the real thing: portal axles, locked differentials and waterproof electronics.
8.8/10our score for this use
Nearly 22 inches long, driven by a high-torque Titan 21T brushed motor through a steel-geared single-speed transmission. Portal axles lift the axle housings clear of the rocks, the differentials are spool-locked front and rear for maximum traction, and the XL-5 HV speed control and receiver box are waterproof.
- Size:
- 1/10 (21.9 inches long)
- Drive:
- Portal-axle 4WD
- Motor:
- brushed motor
What it does well
- Portal axles give it ground clearance that no standard axle layout can match
- Waterproof electronics, so streams, snow and wet rock are all in bounds
- The full Traxxas parts and upgrade network behind a crawler platform
What it does badly
- No battery and no charger in the box, so the real spend is meaningfully higher
- Locked differentials scrub the tires on pavement — this is not a driveway car
- Large and slow: it needs terrain to be interesting, not space to be fast

#3 · Indoor crawling
Axial SCX24
Under eight inches long, four-wheel drive, and it turns a living room floor into a trail.
8.6/10our score for this use
A 1/24 scale crawler — smaller than a shoe — sold as several licensed bodies including Jeep, Ford Bronco, Chevrolet C10 and a Power Wagon. It is a complete ready-to-run package with a small LiPo battery and USB charger, and it crawls over table legs, stairs and garden rockeries at walking pace.
- Size:
- 1/24 (under 8 inches long)
- Drive:
- Full-time 4WD
- Motor:
- brushed motor
What it does well
- Small enough to use indoors year-round, which no other hobby-grade car on this site can claim
- Slow, so crashes barely exist — the failure mode is tipping over, not breaking
- A huge aftermarket of upgrade parts if the hobby sticks
What it does badly
- Tiny. If the person you are buying for wanted something impressive to look at, this is not it
- Not fast, and it never will be
- The included battery is small, so a spare pack is an obvious early purchase

#4 · Scale looks, tiny space
FMS FCX24 Power Wagon
A 1/24 licensed scale crawler with portal axles and a two-speed gearbox, complete with battery and charger.
8.3/10our score for this use
FMS builds small, detailed, licensed crawlers. The Power Wagon is 8.25 inches long, runs portal axles, oil-filled shocks and a two-speed transmission switched from the third radio channel, and arrives with a 7.4 volt 380mAh LiPo and a USB charger.
- Size:
- 1/24 (8.25 inches long)
- Drive:
- Portal-axle 4WD
- Motor:
- brushed motor
What it does well
- Portal axles and a two-speed gearbox at 1/24 scale is genuinely unusual engineering
- Works on a desk, a bookshelf or a flowerbed — the smallest realistic venue of anything here
- Battery, charger and a factory light kit are all included
What it does badly
- At 1/24 it is a display piece as much as a toy; small hands break the scale details
- Spares come from FMS dealers by mail order, not from a local hobby shop shelf
- The 380mAh battery is tiny — plan on buying spares

#5 · A first rock crawler
Redcat Everest Gen7 Sport
A steel-framed scale crawler that arrives with the parts most brands charge extra for.
8.7/10our score for this use
A crawler is the slow, climbing kind of RC car — it is about picking a line over rocks and roots, not speed. Redcat's Gen7 Sport uses a powder-coated 3mm steel ladder frame, oil shocks and beadlock wheels, and comes ready to run.
- Size:
- 1/10
- Drive:
- 4WD, solid axles
- Motor:
- brushed motor
What it does well
- Crawling is quiet, slow and almost impossible to crash — the gentlest hobby-grade experience there is
- Steel ladder frame and real oil shocks out of the box
- Works indoors, in a yard, on a rock pile, in a park — no space requirement
What it does badly
- It is slow by design. A child expecting speed will be disappointed within an hour
- Heavy for its size, so a fall from a real rock can bend steering parts
- The stock radio and servo are the first things people replace
Specifications from Redcat's Everest Gen7 Sport product page.
Why the small one usually wins
The venue decides. A 1/10 crawler on a lawn is bored; it needs rocks, roots and gradients to be interesting, and most people do not have those within walking distance. A 1/18 crawler turns a flowerbed, a gravel driveway or a pile of firewood into a course. That is why the TRX-4M gets driven and the bigger trucks sometimes do not — and it is the same argument we make on RC car scale sizes.
The rivals worth knowing
Traxxas does not have this category to itself. The Axial SCX24 is smaller again and the usual first recommendation in the hobby. The FMS FCX24 Power Wagon brings portal axles and a two-speed gearbox at 1/24 scale for less money. The Redcat Everest Gen7 Sport gives the most 1/10 hardware per dollar of anything here. Traxxas wins on parts availability, and loses on price.
