Fast, fierce, factory-assembled and fully equipped, the 2S capable ARRMA® SENTON™ 4X4 MEGA RTR Short Course Truck is ready to bash right out of the box. Its Spektrum™ STX2® radio with SRX200 receiver includes many of the same features found in high-end 2.4GHz radio systems — throttle and servo reversing, throttle and steering travel adjust, throttle limiting and more. The 12T 550 brushed motor powers the SENTON™ 4X4 MEGA RTR to exciting bashing speeds. Waterproof* electronics and dBoots® Fortress tires carry it through any terrain in any weather. The ingenious ARRMA® modular chassis makes servicing fast and easy. Motor, motor plate, slipper clutch assembly and gear cover are all contained in a single module that can be removed from the chassis by taking out just one screw. Similar modules for the electronics and diff units add to the ease of maintenance. Enjoy full-scale short course truck looks and lots of mud-blasting, dirt-roosting fun with the SENTON™ 4X4 MEGA RTR!
Powered by the MEGA 550 brushed motor system, the ARRMA® SENTON™ 4X4 MEGA RTR Short Course 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 telescoping 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. Side impact nerf bars further protect the chassis and body shell, and shock-absorbing loops keep the front and rear bumpers secured to the chassis, offering defense against heavy impacts.
The SENTON™ 4X4 MEGA RTR Short Course 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.
Tough, multi-spoke black wheels with dBoots® Fortress tires give the SENTON™ 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.
The SENTON™ 4X4 MEGA now comes with IC3™ connectors so you can take full advantage of Spektrum Smart Technology. The IC series of connectors are also designed from the ground up to provide a more solid connection, higher heat resistance, and effortless installation. For those using the popular EC3™ connectors, there's no need to worry. The IC3 connector is entirely backwards compatible.
Both the front and rear diff modules are super-easy to access in the SENTON 4x4 MEGA, ensuring that you spend more time bashing and less time in the workshop.
These differentials are TOUGH. The main differential gears have been super-sized with large pitch gears that have been designed to withstand huge torques, allowing lightweight composite material to be used for reduced rotating mass without compromising strength. The differential internals feature full-metal straight-cut gears, ensuring trouble-free operation.
Easy-access Power Module assembly can be removed from the vehicle in seconds, with the removal of just one single screw. The center shaft assembly* is telescopic to assist with the easy disassembly and is sprung loaded to ensure it stays in position in use.
With the Power Module removed from the vehicle you can easily service your motor, single-pad slipper clutch, spur and pinion gears. The 4x4 MEGA power system features a high-torque 550 sized 12 turn brushed motor.
Easy-access Electronics Module assembly can be removed from the vehicle with the removal of only 5 screws. With this module removed you can access the servo, electronic speed control and the receiver. The two-piece moulding comprises of a lower box and upper lid that are sealed with high-quality rubber seals. The ESC and steering servo are attached to this moulding, while the receiver sits inside the waterproof box.
Soaking up a wide range of surfaces is made easy with the included coil-over-oil shocks. Factory set to handle everything from fast speed runs to snow and mud chucking, no matter where you choose to bash, these high-quality units will keep you stable and in-control. The shock absorbers on the SENTON 4x4 MEGA feature keyed spring perch and self-bleed* design. These shocks are designed to be simple to maintain, yet offer all the performance required to give amazing handling.
Featuring a full-time four-wheel drive, the SENTON 4x4 MEGA is ready to blast through your chosen environment. Telescopic driveshafts in the front, rear and centreline transmit drive from the slipper clutch to each wheel.
High quality dBoots FORTRESS MT tires coupled with multi-spoke wheels offer superb bite on a multitude of surfaces.
