The Arrma Granite Voltage Mega SRS Monster Truck is designed to take you from the back yard to the beach, from the local parking lot to the grass fields and everywhere in between, straight from the box. Fast and tough, this monster is ready to run and ready for action.

The bashing optimized suspension and geometry design means the Granite Voltage Mega SRS is fun and easy to drive on any surface. Built to soak up the most intense all-weather thrills and spills, the Granite Voltage Mega SRS is pumped full of high-quality ARRMA design features, meaning you can conquer anything in your path, and enjoy head-turning Monster Truck looks.

A split-line monocoque-style composite chassis makes up the backbone of the Voltage models. Shock towers, battery compartment, motor mount and gearbox are all integrated into the chassis molding. The transmission design features wide, molded composite gears that offer massive strength and durability. Power is transferred to the driveshafts through a gear differential with all-metal internal gears. The transmission features ball bearings throughout for smooth and efficient operation.

The Arrma 20T 540 brushed motor sits within the chassis in a mid motor position, protecting it from dirt, water and heavy rear-end impacts. An Arrma Mega SRS 3-in-1 Unit combines the ESC, receiver and electronic control element of the servo. It features three different battery modes that are user selectable by positioning a jump connector. An industry standard 3-wire servo can be plugged into the MEGA SRS 3-in-1 Unit. The ARRMA ADS-5 SRS servo is compatible with the SRS 3-in-1 Unit. It generates 70 oz-in (5kg-cm) of torque and has a 60 degree transit time of 0.12s at 6V.

The Arrma Voltage models get you shredding with two lithium-ion batteries and a two-cell lithium-ion charger in the box, and you can add an extra two or four Arrma lithium-ion 18650 cells (not included) to double or triple your run-time! Plus, you can choose Li-Ion, NiMh or LiPo batteries to power your model. The ARRMA Voltage has multi battery chemistry compatibility that allows you to run 2, 4 or 6 ARRMA Li-Ion batteries, or hobby standard 6-cell NiMh or 2S LiPo battery packs.
