SIGNATURE EASY-ACCESS MODULAR DESIGN
The 1/10 scale SENTON 4X2 BOOST 550 MEGA Brushed 2WD short course truck incorporates the signature ARRMA easy-access modular design. Separate, easily removable chassis modules for the power system, electronics, and differential components make routine maintenance fast and simple.
STRONG COMPOSITE CHASSIS
Contributing to the SENTON 4X2 BOOST short course truck’s unstoppable performance are a strong composite chassis; steering with more clearance for stones; a castellated slipper pad and sliding gear mesh; and rubber-shielded bearings throughout. Extended height dirt defenders limit the amount of dirt and debris that can get into the chassis tub.
UPGRADEABLE TRANSMISSION
Using the 4X4 BOOST Transmission Upgrade Set (sold separately), the 1/10 scale SENTON 4X2 BOOST 550 MEGA Brushed 2WD short course truck can easily be upgraded for the extra traction of 4-wheel drive in just three simple steps.
UPGRADEABLE POWER SYSTEM
The 1/10 scale SENTON 4X2 BOOST 2WD short course truck is based on the proven ARRMA 4X4 platform. That means you can easily upgrade from its included 550 MEGA brushed power system to 3S brushless power whenever you’re ready for the increased performance.
MULTI-TERRAIN dBOOTS TIRES
Tough, multi-spoke black SC wheels with vented, multi-terrain dBoots Fortress SC tires give the SENTON 4X2 BOOST 2WD effective traction for bashing almost anywhere, from dirt and grass to parking lots, paved, and asphalt surfaces.
SPEKTRUM SLT2 2.4GHZ 2-CHANNEL TRANSMITTER
The included Spektrum SLT2 transmitter is perfectly balanced for fatigue-free bashing and has a foam wheel for precise fingertip control. New bashers can set the throttle limits at 50% or 75% until ready to use the full speed potential.
