Go with a game changer!

Your path to power begins with the GRANITE VOLTAGE. It arrives ready-to-run out of the box with all the toughness and speed you can handle. Rookie, Intermediate, and Pro settings let drivers practice their skills at their own pace. Two 18650 Lithium-Ion batteries are included, but you can maximize your run time by adding up to four more batteries. With the GRANITE VOLTAGE, ARRMA makes it easy for you to double - or even triple - your off-road fun.

Designed to Be Fast, Designed to Be Tough

The bashing optimized suspension and geometry design means the GRANITE VOLTAGE MEGA SRS is fun and easy to drive on any surface, primed to blast across any terrain.

Ready to Run

A high-quality 2.4Ghz radio transmitter and receiver, wheels and high-performance dBoots tires, waterproof ESC and steering servo and a pre-painted bodyshell are all included as standard. All that is required to get going are four 'AA' batteries to power the transmitter.

Waterproof Electronics

Fully waterproof 3-in-1 unit and steering servo are standard. This means that hitting the roughest terrains, in the most extreme conditions, will be no problem. Rain, mud, snow, dirt and anything else you want to bash your way through.

Maximize Your Run-Time!

The ARRMA VOLTAGE gets you shredding with two lithium-ion batteries included. For added versatility, its quick change battery cradle lets you easily add optional extra Li-Ion batteries - or use your own favorite hobby standard 6-cell NiMh or 2S LiPo battery packs - to double or triple your run-times*.
