Powered by the MEGA 550 brushed motor system, the ARRMA® SENTON™ 4X4 MEGA RTR Short Course Truck is CREATED QUICK, CREATED TOUGH — developed for amazing bashing speeds and severe, all-terrain toughness! Its full-time 4WD transmission with front and rear differentials utilizes strong front, rear, and centerline telescoping driveshafts that can't be lost during heavy effects, unlike dogbones. A basic, dependable, responsive steering assembly complements the ultra-reliable drive system and features a servo horn with integrated servo saver.
The self-bleeding, oil-filled shocks utilize an attempted and checked, coil-over style for basic upkeep and fantastic handling. Their innovative rod end has a molded-in spring perch for additional durability. High chassis guards limit the amount of dirt and debris that can enter the chassis tub. Side effect nerf bars even more protect the chassis and body shell, and shock-absorbing loops keep the front and rear bumpers protected to the chassis, providing defense against heavy impacts.
The SENTON™ 4X4 MEGA RTR Short Course Truck's innovative modular style makes chassis parts simple to gain access to for upkeep. Its power module includes a MEGA 550 motor, motor plate, slipper clutch assembly and gear cover. The power module can be detached from the chassis, as a total unit, by getting rid of just one screw. With the power module got rid of, the slipper clutch can be reached quickly for modifications by taking out three screws that attach the gear cover. The power module style also makes sure that pinion and stimulate gear mesh is ideal every time, using numbered holes for various pinion gear sizes.
A two-piece molding screwed to the truck's chassis acts as its electronic devices module, consisting of a water resistant radio box, servo install, and ESC tray. The radio receiver installs inside the radio box for security from dirt and moisture. The ultra-compact ESC is screwed to the top of the module, allowing fast access to the on/off switch, while the servo installs to the side. All three parts can be removed together, quickly and easily.
The differential module houses each put together differential unit in an ingenious yoke style. Just 8 screws need to be removed to launch the front and rear yokes. The power module can then be detached, allowing you to pivot the transmission cases for access to the differentials. Each differential gear case features large pitch gears that are engineered to withstand substantial torque. Internal metal gears have actually been selected for reliability during severe bashing.
Tough, multi-spoke black wheels with dBoots® Fortress tires give the SENTON™ 4X4 MEGA RTR effective traction for bashing on nearly any surface. Several battery types can be utilized with the hook-and-loop installing, from 6-cell NiMH packs to a 2S block pack.
