This 392-piece set lets children assemble a tracked car, a tumbler robot or a racing tank. Two powerful motors drive four wheels on each large track, giving each model realistic movement. The kit is designed for ages 8 to 14 and encourages hands-on engineering play.

Rechargeable Power and Quiet Indoor Play

A built-in rechargeable battery charges via USB in 1.5 hours and delivers up to 25 minutes of continuous run time. The 2.4 GHz remote controls all directions plus 360-degree rotation without cables. Multiple kits can operate together on different frequencies for group races.

Simple Setup for Solo or Team Building

The ABS plastic blocks are BPA-free and hold together firmly during active play. No soldering, special tools or external power supply are needed — just charge and build. The set works indoors or outdoors and supports independent or collaborative construction, freeing up table space for other activities.

Questions about this item

How do I install the built-in rechargeable battery in the tracked car, and what step do people often miss?

The battery is already built into the chassis; charge it via USB for 1.5 hours before first use — the step many skip is waiting for a full charge instead of running it after a few minutes.

What maintenance or replacement will the USB-rechargeable power pack need later?

The internal pack is not user-replaceable; when runtime drops well below the 25 minute baseline after many cycles, the whole vehicle must be retired.

What limit appears first during sustained play with the 2.4 GHz remote?

After roughly 25 minutes of continuous driving the built-in battery empties and the model stops until recharged for 1.5 hours.
