Granite 4X4 MEGA 550 SLT3 Monster Truck RTR Blue, with battery and charger

Overview

Fast, rugged and factory-built, the 2S LiPo-compatible ARRMA¬ GRANITET 4X4 MEGA RTR comes ready to bash in any terrain. This version features new equipment that further increases the original monster truck's already impressive performance and durability.

The GRANITET 4X4 MEGA RTR Monster Truck is DESIGNED FAST, DESIGNED TOUGH - built for exciting bashing speeds and extreme, all-terrain durability. New features to enhance its unstoppable performance include a stronger chassis and retained hinge pin plates; steering with more clearance for stones; a castellated slipper pad and sliding gear mesh; and rubber shielded bearings throughout.

The monster truck now also includes the SpektrumT SLT3T transmitter and SLR300 receiver. The transmitter is ergonomically designed for long periods of fatigue-free bashing and has a foam wheel for precise fingertip control plus an improved hand grip and trigger feel. New bashers will be able to set throttle limits at 50% or 75% until they are ready to use the full speed potential. The SLT3T is compatible with Tactic¬ SLTT receivers to run other RTR vehicles you may own, and includes a third channel to control optional features such as lights and winches on models that have them.

It retains the ingenious modular design perfected by ARRMA¬ engineers for easy component access and maintenance. The power module, with improved dirt management, 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 gear ratio can be finely tuned as the power module now uses a sliding motor mesh design.

A two-piece molding screwed to the truck's chassis serves as its electronics module, containing a waterproof receiver box, servo mount and ESC tray. The SLR300 receiver mounts inside the receiver 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 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 differential access. The GRANITET 4X4 MEGA RTR comes brushless-ready with 37T 1.35mod diffs with silicone O-rings. The large gears can withstand huge torque, and internal metal gears have been chosen for reliability during extreme bashing.

Its full-time 4WD transmission 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 GRANITET 4X4 MEGA RTR includes the waterproof SpektrumT SPMS650 digital servo for 20% more torque than the previous version's ADS-5 servo.

The self-bleeding, oil-filled shocks, now with silicone O-rings, use a tried and tested, coil-over design for simple maintenance and amazing handling. Their innovative rod-end has a moulded-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.

Tough, multi-spoke black MT wheels with dBoots¬ FortressT MT tyres give the GRANITET 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. This version comes with a Dynamite¬ 3300 mAh 8.4V 7-cell Speedpack¬ 2 Hump NiMH battery that provides 35% more run time compared to the 2400mAh pack of its predecessor.
