Complete the journey from beginner bashing to amplified RC action with one remote control truck, the ARRMA SENTON 4X2 BOOST 550 MEGA Brushed 2WD. Don’t let the low price fool you. Though ready-to-run and easy to drive — only a battery and charger are required — the aggressive 1/10 scale RC short course truck styling tells the true story. It’s got the brushed motor muscle to reach 30+ mph under optimum conditions. And with its rugged chassis, wide wheelbase, and vented tires, the ARRMA SENTON 4X2 BOOST puts the hammer down on nearly any off-road or paved surface, with smooth handling that lets you look like a short track RC truck champion. Thanks to an innovative modular chassis by the ARRMA design team of enthusiasts, maintenance and repairs are fast and hassle-free. To ease yourself into extreme RC truck racing fun, use the Spektrum radio’s throttle limiting feature to cap speed at 50% or 75% until you’ve acquired more trigger time. You won’t always be a new driver, of course, and the brushless-ready design of the ARRMA SENTON 4X2 BOOST SCT RC truck lays the perfect foundation for your next steps. Make and break new speed records by upgrading to 3S brushless power. Then install the ARRMA 4X4 BOOST Transmission Upgrade Set (ARA210003, sold separately) for unstoppable 4WD traction!

Product Overview





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.




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.




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.




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.

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.




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.
