Arrma 1/10 Granite Mega 550 Brushed 4WD MT RTR
Powered by the MEGA 550 brushed motor system, the ARRMA® GRANITE™ 4X4 MEGA RTR Monster Truck is DESIGNED FAST, DESIGNED TOUGH — built for exciting bashing speeds and extreme, all-terrain durability! Its full-time 4WD transmission with front and rear differentials uses strong front, rear, and centerline telescopic driveshafts that can't be lost during heavy impacts, unlike dogbones. A simple, dependable, responsive steering assembly complements the ultra-reliable drive system and features a servo horn with built-in servo saver.
The self-bleeding, oil-filled shocks use a tried and tested, coil-over design for simple maintenance and amazing handling. Their innovative rod end has a molded-in spring perch for extra toughness. High chassis guards limit the amount of dirt and debris that can get into the chassis tub. Shock-absorbing loops keep the front and rear bumpers secured to the chassis, offering defense against heavy impacts.
The GRANITE™ 4X4 MEGA RTR Monster Truck's ingenious modular design makes chassis components easy to access for maintenance. Its power module consists of a MEGA 550 motor, motor plate, slipper clutch assembly and gear cover. The power module can be detached from the chassis, as a complete unit, by removing just one screw. With the power module removed, the slipper clutch can be reached easily for adjustments by taking out three screws that attach the gear cover. The power module design also ensures that pinion and spur gear mesh is perfect every time, using numbered holes for different pinion gear sizes.
A two-piece molding screwed to the truck's chassis serves as its electronics module, containing a waterproof radio box, servo mount, and ESC tray. The radio receiver mounts inside the radio box for protection from dirt and moisture. The ultra-compact ESC is screwed to the top of the module, allowing quick access to the on/off switch, while the servo mounts to the side. All three components can be removed together, quickly and easily.
The differential module houses each assembled differential unit in an innovative yoke design. Only eight screws need to be removed to release the front and rear yokes. The power module can then be detached, allowing you to pivot the gearbox cases for access to the differentials. Each differential gear case features large pitch gears that are engineered to withstand huge torque. Internal metal gears have been chosen for reliability during extreme bashing.
Finally, tough, multi-spoke black wheels with dBoots® Fortress tires give the GRANITE™ 4X4 MEGA RTR effective traction for bashing on almost any terrain. Multiple battery types can be used with the hook-and-loop mounting, from 6-cell NiMH packs to a 2S block pack.
