Overview
If you're looking for your first hobby-quality RC basher automobile, absolutely nothing else compares to ARRMA 4X2 INCREASE 550 MEGA Brushed 2WDs. It's not simply the characteristic ARRMA speed and sturdiness that sets them apart. Based upon the proven ARRMA 4X4 platform, ready-to-run 4X2 INCREASE 550 MEGA Brushed 2WD automobiles can be updated easily to 4-wheel drive and 3S brushless power whenever you're all set. What's more, they also use terrific value.

Even without those upgrades, the SENTON 4X2 INCREASE 550 MEGA Brushed 2WD brief course truck can reach speeds of 30+ miles per hour in maximum conditions utilizing optional gearing. For all-terrain strength, it includes a strong composite chassis and kept hinge pin plates; steering with more clearance for stones; a castellated slipper pad and moving gear mesh; and rubber shielded bearings throughout. The SENTON 4X2 BOOST is crafted to outlast other beginner-level bashers.

It maintains the innovative modular chassis style improved by ARRMA engineers for easy part access. Different, easily detachable modules for the power system, electronic devices, and differential elements make routine automobile maintenance quickly and simple.

The self-bleeding, oil-filled shocks with silicone O-rings utilize an attempted and checked, coil-over style for uncomplicated maintenance and fantastic handling. Their innovative rod-end has a molded-in spring perch for additional strength. High chassis guards restrict the amount of dirt and debris that can get into the chassis tub. Shock-absorbing loops keep the front and rear bumpers protected to the chassis, using defense versus heavy impacts.

The SENTON 4X2 INCREASE 550 MEGA Brushed 2WD brief course truck includes the Spektrum SLT2 transmitter and SLT 2-in-1 40A ESC and receiver. The transmitter is ergonomically designed for extended periods of fatigue-free driving and has a foam wheel for accurate fingertip control. New drivers will have the ability to set throttle limitations at 50% or 75% till all set to let loose the complete speed potential.

Tough, multi-spoke black SC wheels with vented dBoots Fortress SC tires offer the SENTON 4X2 INCREASE 550 MEGA Brushed 2WD efficient traction for bashing on almost any surface — including off-road, dirt, yard, parking lots, paved and asphalt surfaces.

The SENTON 4X2 BOOST is brushless-ready, so you can easily upgrade from its included 550 MEGA brushed power system to 3S brushless power whenever you're all set for the increased performance. And with the 4X4 BOOST Transmission Upgrade Set (ARA210003, sold individually), the additional traction of 4-wheel drive is simply three basic actions away!
