Furitek TerraX Active Pro 4WS - 1/18 ARTR Crawler
A carbon-fiber micro crawler built around selectable 4-wheel steering and smooth Furitek brushless power
The Furitek TerraX Active Pro 4WS is a pre-assembled 1/18-scale ARTR mini crawler designed for rock lines, narrow gates, and obstacles where accurate tire placement matters. A full carbon-fiber chassis, aluminum suspension components, two steering servos, and Furitek brushless electronics give the platform a competition-minded foundation straight out of the box.
Independent front and rear steering is the centerpiece of the design. The included transmitter lets you move among front steer, rear steer, coordinated 4WS, and crab-walk modes, opening up tighter turns and more deliberate chassis positioning than a front-steer-only crawler can provide.
ARTR battery requirement: The assembled crawler and radio system do not include a drive battery. Choose a 2S-3S LiPo pack near Furitek's recommended 0.5 x 1.12 in. (13 x 28 mm) size with a PH 2.0 connector compatible with the stock SCX24-style battery connection.

Key Features of the Furitek TerraX Active Pro 4WS
Independent Four-Wheel Steering Dedicated front and rear steering control lets you choose how each axle responds. Front steer, rear steer, full 4WS, and crab walk give you practical options for clearing tight gates and setting up the next climb. |
Carbon-Fiber Chassis A rigid carbon-fiber chassis supports the drivetrain without unnecessary bulk. Magnetic body mounts also make access to the battery and electronics fast and uncluttered. |
Micro Stellar Brushless System Furitek's compact Micro Stellar transmission and 2-in-1 outrunner system focus on controlled low-speed delivery and crawler-ready torque. Compatible smartphone tuning puts throttle, brake, and drive adjustments within easy reach. |
ARTR Control Package The radio, receiver, brushless system, and dual steering servos arrive installed. Fit an appropriate 2S-3S LiPo, inspect the steering and drivetrain, and the TerraX is close to trail-ready. |
High-Clearance Geometry Aluminum high-clearance links work with the 10-degree aluminum skid to help the chassis pass over ledges and demanding breakover points with fewer hang-ups. |
Weighted Crawler Tires Integrated brass hex weights keep added mass low and close to the wheels. That placement supports a planted feel on steep faces and off-camber sections. |
How the Four-Wheel Steering Modes Work
Four-wheel steering changes both the way the crawler turns and the way it shifts around an obstacle. With practice, it can save multi-point resets and create a cleaner approach where a conventional front-steer rig would need to back up.
| Steering Mode | Best Use |
|---|---|
Front steering |
Use for familiar, predictable control on open trail sections. |
Rear steering |
Move the rear axle into position while holding the front tires on the selected line. |
Full 4WS |
Turn the axles in opposite directions for a substantially tighter turning path. |
Crab walk |
Point both axles the same way to move diagonally and shift the rig sideways around an obstacle. |
Battery Fitment and First-Run Setup
Battery dimensions matter on the compact TerraX chassis, where clearance around the transmission, electronics, and body is limited. Furitek recommends a pack around 13 x 28 mm with a PH 2.0 connector like the stock SCX24 battery connection.
- Confirm that the LiPo is a supported 2S or 3S pack and seats naturally without pressure against the chassis.
- Match the connector and verify polarity before making the first connection.
- Adjust steering endpoints so the front and rear servos do not bind at full lock.
- Lift the crawler and confirm that every wheel turns freely throughout the full steering sweep.
- Begin with conservative Furitek app settings, then tune throttle and braking for your terrain.
Furitek TerraX Active Pro Pros and Cons
| What Works Well | Limitations and Context |
|---|---|
Independent 4WS makes the TerraX unusually maneuverable through technical sections. |
Rear steering brings a learning curve; practice at low speed makes centering it more consistent. |
Carbon fiber, aluminum links, steel driveshafts, and weighted tires create a well-equipped starting point. |
Specialized hardware rewards regular checks for loose fasteners, servo bind, and driveline contact. |
The Micro Stellar brushless system combines low-speed control with convenient app-based adjustment. |
More aggressive settings and 3S power may add heat and component load, so tune for the course rather than maximum output. |
ARTR assembly shortens bench time because the electronics and radio gear are already in place. |
You still need a correctly sized battery and charger, so verify pack dimensions before ordering. |
Is the Furitek TerraX Active Pro 4WS Right for You?
The Furitek TerraX fits drivers who want more positioning control than a typical 1/18 crawler and are comfortable setting endpoints, checking battery fitment, and handling routine maintenance. Its four steering modes are most valuable on technical indoor courses, rock gardens, and narrow gates where precision takes priority over speed.
A first-time buyer seeking the simplest RTR experience may be happier with a front-steer model that includes a battery and charger. For hobbyists who value carbon-fiber construction, Furitek brushless control, and advanced maneuverability, the TerraX Active Pro delivers a focused and highly tunable mini-crawler package.

Frequently Asked Questions
What is the Furitek TerraX Active Pro 4WS?
The TerraX Active Pro 4WS is a 1/18-scale ARTR mini rock crawler. It combines a carbon-fiber chassis, Furitek brushless power, and independent control of the front and rear steering.
Does the Furitek TerraX include a battery?
No. You need a compact 2S-3S LiPo battery plus a compatible balance charger. Furitek recommends a pack around 13 x 28 mm with a PH 2.0 stock SCX24-style connector.
What does ARTR mean?
ARTR stands for Almost Ready to Run. The motor, ESC, receiver, steering servos, and transmitter system are supplied with the assembled crawler, while the drive battery and charger are sold separately.
What steering modes does the TerraX Active Pro support?
The radio system provides front steering, rear steering, coordinated four-wheel steering, and crab-walk movement. Use them to tighten the turning path or shift the crawler into a better position around technical obstacles.
Can the Furitek TerraX run on 3S?
Yes. The listed battery range is 2S-3S LiPo, but pack dimensions and connector polarity still need to match. Start with conservative app settings when using 3S power.
Can the Furitek TerraX be tuned from a phone?
Yes. With a compatible smartphone, Furitek app tuning lets you adjust throttle, braking, and drive response without connecting the crawler to a computer.
Is the Furitek TerraX suitable for beginners?
A newer hobbyist can drive it, but the 4WS controls add more complexity than a basic front-steer RTR. The best fit is a driver comfortable with steering endpoints, LiPo care, and regular crawler maintenance.
