Redefine traversable!

1/8 ST-4 G3 Brushless 4WD 2.4GHz RTR BMW M3 GT2

A race-spec cross between a stadium truck and a monster truck, the ST-4 G3 is powered by a brushless 2000 kV motor to dominate any terrain you put it on. This racer is ready to conquer straight out of the box but still gives you plenty of options for adjusting ride height plus camber and caster tuning.

Anything the terrain can dish out this beauty can handle. The equipped 80A brushless ESC has multiple protection features and a waterproof, dustproof case making the ST-4 nearly impossible to stop.
