Hobby Plus CR18P Terranaut 1/18 Scale 8x8 Brushed RC Rock Crawler Ready-to-Run

The Hobby Plus CR18P Terranaut is a 1/18 scale 8x8 rock crawler built for drivers who want something different from a traditional 4WD trail truck. Featuring an eight-wheel-drive drivetrain, three solid axles, and a detailed expedition-style body, the Terranaut is designed to tackle technical trails while maintaining a realistic scale appearance. Its compact size makes it equally at home on indoor crawler courses or outdoor trails, making it suitable for beginners and experienced crawler enthusiasts alike.

Performance

The Terranaut is powered by a brushed motor that delivers smooth throttle response and the low-speed torque needed for technical crawling. Its permanent 8x8 drivetrain distributes power to all eight wheels, helping maintain traction when climbing rocks, crossing loose terrain, or navigating uneven surfaces. Three locking axle assemblies and generous suspension articulation allow the truck to keep more tires in contact with the ground, improving stability over obstacles. While it is capable of moderate trail speeds, the drivetrain is optimized for crawling rather than fast driving.

Design and Features

The expedition-inspired body features realistic styling with molded accessories, a pickup-style rear bed, detailed grille, roof rack, and off-road equipment that enhance its scale appearance. The ladder-frame chassis supports three solid axles connected by a multi-link suspension system, giving the crawler impressive articulation. Oversized all-terrain tires provide additional grip while maintaining a realistic scale look.

Control

The included 2.4GHz proportional radio system provides smooth throttle and steering control for accurate maneuvering through technical sections. The responsive steering allows precise wheel placement, while the stable radio connection makes the crawler suitable for both indoor obstacle courses and outdoor trail exploration.

Build Quality

The CR18P platform combines reinforced plastic components with metal drivetrain parts in key locations for improved durability. Oil-filled shocks help absorb uneven terrain, while metal gears and durable driveshafts are designed to withstand the additional load created by the eight-wheel drivetrain. The modular chassis layout also allows relatively easy servicing and future upgrades.

Ease of Use and Maintenance

This Ready-to-Run model arrives fully assembled with electronics installed. Routine maintenance includes cleaning dirt from the axles, suspension, and drivetrain after trail use, along with periodically checking hardware and lubricating moving parts. The compact chassis offers good accessibility for routine servicing and customization.

Special Notes

This is a Ready-to-Run model, including the crawler, 2.4GHz transmitter, brushed motor, ESC/receiver unit, rechargeable Li-ion battery, and USB charger. Install AA batteries in the transmitter (not included), charge the included battery, and the truck is ready for the trail. Popular upgrades include brass axle weights, aluminum suspension links, beadlock wheels, metal steering components, and softer crawler tires for increased climbing performance.
