Overview

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!
