Overview
With ARRMA's legendary toughness and speed, the 1/10 scale Outcast 4S stunt truck is capable of much more than just standard off-road driving. Its short 313 mm wheelbase makes stunts like backflips and nimble maneuvering through technical terrain easier than ever.
Based on the latest evolution of the 4S BLX platform – the affordable middle ground between agile 3S BLX vehicles and larger, more powerful 6S machines – this version of the OUTCAST is ready for amped-up, all-road stunts and action! Featuring the updates that drivers most desired, including a reinforced chassis with space for a middle diff.
ARRMA has also boosted the 4S-capable Spektrum brushless power system of the Outcast stunt truck for more intense all-road action. A cooler Spektrum Firma 120A Smart V2 waterproof ESC with IC5 connectors (EC5 compatible) provides extra punch and improves the driving feel. The steering power has been bolstered with a Spektrum S662 metal-geared digital servo with an aluminum housing. Its higher torque improves the truck's maneuverability at high speeds.
These updates join a host of proven ARRMA 4S BLX features – from high shock towers and oil-filled shocks with long travel to steel differential gears and EXtreme Bash drive shafts for unstoppable power transfer. The Outcast 4S BLX also includes ARRMA's popular easy-access modular design to make routine maintenance quick and simple.
Made from high-quality rubber, the vented dBoots BACK-FLIP LP tires feature an aggressive tread pattern that secures a solid grip on a wide range of surfaces. The vintage truck body has a sturdy rear wing and is finished in two new color schemes. Front and rear bumpers provide protection against impacts, and a wheelie bar with rubber tires offers stunt capabilities.
Everything in the durable design contributes to confident driving and responsive handling for any dazzling stunts you can imagine. Fully Ready-to-Run, the ARRMA Outcast 4S BLX stunt truck comes with a 3-channel Spektrum SLT3 2.4GHz radio and a dual protocol SR315 receiver. Simply charge up, and you're ready to start performing breathtaking new stunts!
