This product has been discontinued.

The TXT-1 is designed like a full-size monster truck with an aluminum ladder frame and multi-link suspension. Solid axles with a cantilever system allows for massive suspension articulation. This kit includes hardware and a second servo saver for four wheel steering. The servos are located next to the axles for direct steering. The kit requires a 2 or 3 channel radio and can operate on a 7.2V or 8.4V battery.

Chassis for the Tamiya 58280 TXT-1.

The Tamiya TXT-1 (Tamiya Xtreme Truck) is the ultimate 1/10 scale monster truck chassis, making it a great starting point for a medium-sized outdoor robot. The 4 x 4 x 4 chassis gives you power and steering on all four wheels for maximum control and maneuverability of your robot. The gear ratio is higher than on many similar-looking models since this truck is geared toward rock climbing rather than racing. The stock cantilever suspension system provides a huge amount of travel to help ensure that you won’t get stuck.

The kit includes two 540-sized motors and most of the hardware and mechanical components necessary to get up and running. For typical radio control installations, a radio system and 6-cell battery are necessary; for robotics applications, a high-power motor controller and robot controller would replace the RC receiver. Each pair of wheels is steered by a separate servo, so two servos are required to achieve four-wheel steering. Due to the size and weight of the chassis, we recommend high-torque or giant servos for the best control.

This R/C machine packs all the power of an American monster truck. Tamiya invites you to feel the rumble of parallel twin motors transferring power to the propeller shaft and front/rear axles as this bad-boy takes on extreme 4 x 4 off-road action.

Heavy-duty Parts for Rugged Driving

Aluminum side frames and suspension arms add a customized feel and ensure high durability. The TXT-1 features a 2-level gearbox for efficient power transmission.

High Performance Wheels

The 4-link rigid wheels feature push rods and locking arms as well as dampers that employ cantilever suspension. The extraordinary suspension stroke and monster tires allow the TXT-1 to handle the hardest of roads.
