1/5 OUTCAST 8S BLX 4WD Brushless Stunt Truck RTR (ARA5810)

Driven by 8S brushless power and an ARRMA®-tough design, the OUTCAST™ 8S BLX 4WD delivers the torque, acceleration and speed you need for extreme action in 1/5 scale. This ready-to-run stunt truck comes equipped to defy gravity right out of the box.



From the heavy-duty front bumper to the wheelie bar in back, it's engineered to do it all: long, tall wheelies; tight, fast donuts; standing and aerial backflips; high leaps into the air; and more — over all terrain, in all conditions.

Just add your choice of batteries and charger and go. The OUTCAST™ 1/5 8S BLX 4WD includes a Spektrum™ DX3™ Smart transmitter and SRS6110AT AVC® (Active Vehicle Control®) receiver that take full advantage of the Spektrum™ Smart Firma™ brushless motor and ESC's innovative telemetry capabilities. Download the free Spektrum™ Dashboard App to your mobile device and follow motor RPM, ESC temperature, receiver voltage, drive pack voltage and more data in real-time. Dial-in extra stability with the radio's AVC® system to carve corners and nail jumps without letting up on the throttle.

Bigger than big and engineered for brute power and toughness, the ARRMA® 1/5 scale OUTCAST™ 8S BLX 4WD Stunt Truck features a metal-reinforced design that lets you blast up, over and through bruising obstacles. Metal shafts, turnbuckles and outdrives, plus all-metal internal gears, give the drivetrain and suspension system unstoppable strength. Even the included Spektrum™ S905 digital servo boasts the strength of metal gears.

The extra-rigid, laser-etched, anodized aluminum chassis plate has a multi-structured center brace system, rear lower chassis brace and strong composite chassis side pods for the durability to support extreme stunts. Extra-thick molded composite front and rear shock towers hold massive 20mm bore, oil-filled adjustable shocks to soak-up bumps and jolts.

ARRMA® keeps your maintenance time to the minimum with an efficient, driver-friendly design. A sliding, 3-bolt aluminum mount provides fast motor access. The vehicle's front, rear and center modules and waterproof electronics module are also engineered for quick and easy access, removal and maintenance.

The ultra-tough OUTCAST™ 1/5 8S truck body arrives factory trimmed, painted and decaled. A center protection tower on the chassis interfaces with the roll cage for increased body durability. Its tough stunt truck wheels come outfitted with metal 24mm hex inserts and multi-terrain dBoots® BACKFLIP tires that provide all the traction you'll need to flip, grip, wheelie and spin. A high downforce wing helps keep the vehicle grounded — and a wheelie bar is there for when only 90 degree wheelies will do!

Size doesn't equate to scale. 1/10th Short Course is the same size as 1/8th Buggy. This is a short wheelbase truck by design, so the fact it's only two inches shorter than a normal wheelbase vehicle like the X-Maxx means it could be a scale larger (though, yeah, lots of this stuff IS sort of subjective).

You can have a 1/10 scale dragster that has a longer wheelbase than a 1/5 scale Xmaxx

The RJ Speed 1/10 Electric Dragster 2WD Kit 24" has a 5 inch LONGER wheelbase than a Xmaxx.
