Overview

The best short course RC truck for first-time bashing through amplified all-road blasting is the ARRMA SENTON 4X4 MEGA 550 RTR. Though easy to drive, affordably priced, and ready-to-run — its aggressive 1/10 scale styling hints at high-speed excitement that’s ahead. Speeds of 30+ mph are achievable under optimum conditions. From its full-time 4WD transmission to the large diff gears, every part of the ARRMA SENTON 4X4 MEGA 550 has been engineered by the ARRMA design team of RC enthusiasts to survive brutal blasting. The remote control short course truck’s smooth handling has you looking like a winner right off the starting line, and its wide wheelbase and vented tires let you put the hammer down on nearly any off-road or paved surface. An innovative modular chassis simplifies maintenance and repairs, cutting down time to the bone. The included Spektrum radio lets you limit top speeds to 50% or 75% of full throttle until you’re ready for it all, and its ergonomic grip fits your hand like a glove. ARRMA recommends a high capacity NiMH battery. You can also upgrade easily to 2S LiPo power to take your RC 4x4 fun to the next level. Fully assembled and ready-to-run, the ARRMA SENTON 4X4 MEGA 550 Brushed RTR just needs batteries and a charger before you’re ready to make your move!
