Overview
Quick, rugged and factory-built, the TWO LiPo-compatible ARRMA® SENTON™ 4X4 MEGA RTR comes all set to slam on any terrain. This variation of the Brief Course truck features new devices that enhances on the original’s already impressive performance and durability.
The SENTON™ 4X4 MEGA RTR Brief Course truck is CREATED QUICK, CREATED HARD — constructed for interesting bashing speeds and severe, all-terrain toughness. New features to improve its unstoppable performance include a stronger chassis and kept hinge pin plates; guiding with more clearance for stones; a castellated slipper pad and moving equipment mesh; and rubber protected bearings throughout.
The Short Course truck now likewise consists of the Spektrum™ SLT3™ transmitter and SLR300 receiver. The transmitter is ergonomically created for long periods of fatigue-free driving and has a foam wheel for exact fingertip control plus an improved hand grip and trigger feel. New bashers will have the ability to set throttle limits at 50% or 75% until they are all set to use the full speed potential. The SLT3™ is compatible with Strategy® SLT™ receivers to run other RTR lorries you may own, and consists of a third channel to control optional features such as lights and winches on models that have them.
It keeps the innovative modular design perfected by ARRMA® engineers for easy element gain access to and maintenance. The power module, with improved dirt management, consists of a MEGA 550 motor, motor plate, slipper clutch assembly and equipment cover. The power module can be removed from the chassis as a complete system by getting rid of just one screw. With the power module eliminated, the slipper clutch can be reached quickly for changes by securing 3 screws that connect the equipment cover. The equipment ratio can be carefully tuned as the power module now uses a sliding motor mesh design.
A two-piece molding screwed to the truck’s chassis works as its electronics module, containing a waterproof receiver box, servo mount and ESC tray. The SLR300 receiver mounts inside the receiver box for security from dirt and moisture. The ultra-compact ESC is screwed to the top of the module, permitting fast access to the on/off switch, while the servo mounts to the side. All 3 components can be gotten rid of together, rapidly and easily.
The differential module houses each differential system in an innovative yoke design. Just 8 screws require to be gotten rid of to launch the front and rear yokes. The power module can then be removed, permitting you to pivot the transmission cases for differential gain access to. The SENTON™ 4X4 MEGA RTR comes brushless-ready with 37T 1.35mod diffs with silicone O-rings. The large gears can endure huge torque, and internal metal gears have been picked for reliability during severe bashing.
Its full-time 4WD transmission uses strong front, rear, and centerline telescopic driveshafts that can’t be lost during heavy impacts, unlike dogbones. An easy, reliable, responsive guiding assembly complements the ultra-reliable drive system and features a servo horn with built-in servo saver. The SENTON™ 4X4 MEGA RTR consists of the water resistant Spektrum™ SPMS650 digital servo for 20% more torque than the previous variation’s ADS-5 servo.
The self-bleeding, oil-filled shocks, now with silicone O-rings, use an attempted and checked, coil-over design for easy maintenance and incredible handling. Their ingenious rod-end has a molded-in spring perch for additional strength. High chassis guards restrict the amount of dirt and debris that can enter the chassis tub. Side effect nerf bars even more safeguard the chassis and body shell. Shock-absorbing loops keep the front and rear bumpers secured to the chassis, providing defense versus heavy impacts.
Tough, multi-spoke black SC wheels with vented dBoots® Fortress™ SC tires offer the SENTON™ 4X4 MEGA RTR reliable traction for bashing on nearly any terrain. Numerous battery types can be utilized with the hook-and-loop installing, from 6-cell NiMH packs to a TWO block pack. This variation includes a Dynamite® 3300 mAh 8.4V 7-cell Speedpack® 2 Hump NiMH battery that supplies 35% more run time compared to the 2400mAh pack of its predecessor.
