Arrma Granite Mega 665 4X4 Brushed Monster Truck Overview

Bash with unbeatable 4x4 grip when you step up to the 1/10 scale ARRMA GRANITE MEGA 665 - a ready-to-run brushed monster truck that offers amped-up power and toughness straight out of the box. Later, when you’re ready for even bigger performance, upgrading it to a brushless power system is drop-in easy.

There’s no better way to start your off-road bashing power trip than with the ARRMA GRANITE. And this updated GRANITE MEGA 665 4x4 takes the popular brushed monster truck’s impressive capabilities to the next level.

A high-torque, 11% larger MEGA 665 brushed motor replaces the 550-size motor of its predecessor, with an aluminum heatsink and 35mm cooling fan to boost efficiency and power. The included transmission is already 3S brushless-ready for future upgrades. It’s also protected against damage from excessive torque by a new, maintenance-free overload coupling.

The all-terrain suspension and oil-filled, coilover shocks soak up bumps. You can adjust the ride height to add more ground clearance for uneven surfaces. In any conditions, the multi-surface dBoots Fortress MT tires provide awesome traction. Extended height side guards on the strong composite chassis help keep onboard components free of dirt and debris.

The GRANITE body comes factory-finished in several fresh color schemes, and now uses a clipless body retention system to preserve its realistic, aggressive looks. High-quality Spektrum electronics round out the ready-to-run package, including an SLT2 2.4GHz transmitter, LiPo-ready SLT 2-in-1 40A ESC/Receiver, and S661 digital metal-gear servo for precise, powerful steering.

Just add your own battery and charger. Then, take your ARRMA GRANITE MEGA 665 4x4 to your favorite dirt, gravel, or short grass bashing grounds. Set up some ramps or dirt mounds. Grab the transmitter, punch the throttle - and get set for some monster bashing fun!
