Furitek TerraX Active Pro 4WS - 1/18 ARTR Crawler
Carbon-fiber mini crawler with independent four-wheel steering and Furitek brushless control
The Furitek TerraX Active Pro 4WS is a 1/18-scale ARTR mini crawler built for technical rock crawling, tight gates and terrain that rewards precise wheel placement. It combines a full carbon-fiber chassis, aluminum suspension hardware, dual steering servos and a compact Furitek brushless power system in a pre-assembled platform.
Its defining feature is independently controlled four-wheel steering. From the included transmitter, the driver can select front steering, rear steering, coordinated 4WS or crab-walk movement to reduce the turning radius, reposition the chassis and approach obstacles from angles that are difficult for a conventional front-steer crawler.
ARTR battery requirement: The crawler and radio system are supplied assembled, but a suitable 2S-3S LiPo battery is required. Furitek lists a recommended pack size of approximately 0.5 x 1.12 in. (13 x 28 mm) and a PH 2.0 connector matching the stock SCX24-style battery connector.

Key Features of the Furitek TerraX Active Pro 4WS
Independent Four-Wheel Steering Separate front and rear steering control gives the driver more ways to position the tires. Switch between front steer, rear steer, full 4WS and crab walk to negotiate narrow gates or line up for difficult climbs. |
Carbon-Fiber Chassis The carbon-fiber chassis provides a rigid, lightweight foundation for the drivetrain and suspension. Magnetic mounts make the Grey body quick to remove when accessing the battery or electronics. |
Micro Stellar Brushless System The compact transmission integrates Furitek's outrunner brushless technology for smooth low-speed response and usable torque. Smartphone app tuning allows throttle, brake and drive behavior to be adjusted without a computer. |
ARTR Control Package The transmitter, receiver, brushless power system and dual steering servos are already installed. Add a correctly sized 2S-3S LiPo battery and complete the normal pre-run checks before crawling. |
High-Clearance Geometry Aluminum high-clearance links and a 10-degree aluminum skid are intended to reduce hang-ups as the chassis crosses ledges and breakover points. |
Weighted Crawler Tires The crawler tires use integrated brass hex weights to place mass low and near the wheels, supporting traction and balance on steep or off-camber obstacles. |
How the Four-Wheel Steering Modes Work
Four-wheel steering is more than a visual feature. It changes how the crawler rotates and translates around obstacles, giving experienced drivers additional control when a standard front-steer vehicle would need to reverse and reset its line.
| Steering Mode | Best Use |
|---|---|
Front steering |
Conventional driving and predictable trail control. |
Rear steering |
Repositions the rear axle while the front tires remain pointed on the chosen line. |
Full 4WS |
Turns the front and rear wheels in opposite directions to tighten the turning radius. |
Crab walk |
Turns both axles in the same direction so the crawler can move diagonally and shift sideways relative to an obstacle. |
Battery Fitment and First-Run Setup
A compact battery is essential because the TerraX chassis has limited space around the transmission, electronics and body. Furitek recommends a pack around 13 x 28 mm, using a PH 2.0 connector like the stock SCX24 battery connection.
- Confirm the LiPo pack is 2S or 3S and physically fits without being forced into the chassis.
- Verify connector type and polarity before plugging in the battery.
- Set steering endpoints so neither servo binds at full lock.
- Check that all four wheels rotate freely through the full steering range.
- Use Furitek app tuning conservatively until throttle and braking response match the terrain.
Furitek TerraX Active Pro Pros and Cons
| What Works Well | Limitations and Context |
|---|---|
Independent 4WS creates a very tight and adaptable crawler on technical courses. |
Rear-steering control adds complexity and takes practice to center consistently while driving. |
Carbon fiber, aluminum links, steel driveshafts and weighted tires provide a premium starting specification. |
The specialized chassis should be inspected regularly for loose hardware, steering bind and driveline interference. |
The Micro Stellar brushless system supports smooth crawling and app-based tuning. |
Aggressive tuning or excessive 3S use can increase stress and heat, so settings should match the course and driving style. |
ARTR assembly reduces setup time because the electronics and radio system are already installed. |
A battery and compatible charger are still required, and pack dimensions are critical for proper fitment. |
Is the Furitek TerraX Active Pro 4WS Right for You?
The Furitek TerraX is best suited to RC crawler enthusiasts who want more steering control than a conventional 1/18 platform and are comfortable with endpoint adjustment, battery fitment and routine maintenance. Its four steering modes are especially useful on technical indoor courses, rock gardens and narrow gates where chassis positioning matters more than speed.
Drivers looking for a simple beginner RTR may prefer a conventional front-steer crawler with a battery and charger included. Buyers who value carbon-fiber construction, Furitek brushless control and advanced maneuverability will find the TerraX Active Pro offers a distinctive, highly tunable mini-crawler package.
