<h1>ARRMA ARA102690 1/10 KRATON 4x4 4S BLX Brushless Speed Monster Truck Red</h1> <p>Powered by the BLX120 brushless system, the KRATON™ 4X4 4S BLX is unstoppable on trails, race tracks, and muddy courses. Its 2400Kv brushless motor is matched to an ESC with dual EC5™ connectors for using two 2S LiPo batteries. Differential gears inside the front and rear gearboxes are made of durable metal.</p> <p>To develop the chassis, ARRMA® engineers started with the proven 4X4 3S platform. They stretched the track width by widening the suspension and drive shafts, and added a center brace along the length of the chassis for maximum durability (it can be removed in just four quick steps when it's time to perform maintenance). The molded 16mm Big Bore shocks include top-loading springs and molded-in shock rod ends to prevent spring loss.</p> <p>The body has the same aggressive styling as that of the KRATON™ 6S BLX, with a smaller version of its rear wing. There are also many subtle tweaks that give the KRATON™ 4X4 4S BLX a personality all its own. Large, tough wheels hubs and durable 17mm wheel hexes hold standard 3.8" wheels, outfitted with low-profile MINOKAWA LP tires.</p> <p>Included with the ready-to-run package is a Spektrum™ STX2® 2.4GHz radio with SRX200 waterproof receiver and an ARRMA® ADS-15M metal gear servo. Just add your choice of battery, charger, and "AA" transmitter batteries – and start unleashing ARRMA® monster speed and performance in a whole new size.</p> <p>FEATURES:</p> <ul> <li>ARRMA® speed and toughness</li> <li>4S-capable BLX120 Brushless Power System for 50+ mph speed</li> <li>Performance approaching the KRATON™ 6S BLX in a smaller, yet still beast-like setup</li> <li>Spektrum™ STX2® 2.4GHz Radio System</li> <li>2-Channel SRX200 waterproof receiver</li> <li>Built-in 3-position throttle limiter</li> <li>Extended range and interference-free performance</li> <li>Throttle/steering reversing</li> <li>Throttle/steering travel adjust</li> <li>Throttle limiting</li> <li>ADS-15M waterproof metal-gear high-torque servo</li> <li>2400Kv brushless motor with large heatsink</li> <li>BLX120 ESC with dual EC5™ battery connectors for two 2S LiPo packs</li> <li>Lengthened suspension arms and driveshaft for wider track than 3S BLX vehicles</li> <li>Center chassis brace for maximum durability</li> <li>Metal spur gear and castellated slipper pads</li> <li>Enlarged front and rear hubs for added strength</li> <li>Durable 17mm aluminum hexes</li> <li>16mm big bore shocks with molded-in shock rod end and top-loading spring</li> <li>Front and rear gearboxes with metal internal differential gears</li> <li>New wing, wing mounts, and bumpers</li> <li>New body mounts</li> <li>Low-profile MINOKAWA tires</li> <li>ADS-15M metal gear servo</li> <li>2-year limited warranty</li> </ul> <p>SPECIFICATIONS:</p> <ul> <li>Ball Bearings: Full set</li> <li>Chassis: Molded composite</li> <li>Completion Level: Ready-To-Run</li> <li>Drivetrain: 4WD</li> <li>Front Shock Spring Rate: 0.8N/mm</li> <li>Product Height: 7.56" (192mm)</li> <li>Top Speed: 50+</li> <li>Wheel Hex Size: 17mm</li> <li>Final Drive Ratio: 12.48</li> <li>Motor Type: Brushless</li> <li>Speed Control: Included</li> <li>Wheelbase: 12.87" (327mm)</li> <li>Approximate Assembly Time: No assembly required</li> <li>Body: Molded polycarbonate, trimmed and painted with decals applied</li> <li>Pinion: 13T</li> <li>Scale: 1/10</li> <li>Product Weight: 7.99 lbs (3.63 kg)</li> <li>Tire Tread: Minokawa</li> <li>Vehicle Type: Monster Truck</li> <li>Water-Resistant: Yes</li> <li>Power Type: Electric</li> <li>Gear Pitch: 0.8 Module</li> <li>Servos: Included</li> <li>Motor Size: 3668</li> <li>Product Length: 20.79" (528mm)</li> <li>Spur Gear: 57T</li> <li>Suspension: Independent</li> <li>Outer Diameter: 6.1 in (155mm)</li> <li>Power System: 4S</li> <li>Product Width: 15.55" (395mm)</li> <li>Radio: Included</li> <li>Bushing Material: Metal</li> <li>Charger: Sold Separately</li> <li>Differential: Oil-filled metal gear</li> <li>Max Battery Dimensions: 6.50 x 2.01 x 1.89" (165 x 51 x 48mm)</li> <li>Rear Shock Spring Rate: 0.7N/mm</li> <li>Battery: Sold Separately</li> <li>Ground Clearance: 2.28" (58mm)</li> <li>Internal Gear Ratio: 2.85:1</li> <li>Receiver: Included</li> <li>Shock Type: Oil-filled, coil over spring</li> <li>Wheel Type: MT</li> </ul> <p>INCLUDES:</p> <ul> <li>(1) ARRMA KRATON™ 4x4 4S BLX Vehicle</li> <li>(1) Spektrum SRX200 Waterproof Receiver (installed)</li> <li>(1) ARRMA® ADS-15M Metal Gear Servo (installed)</li> <li>(1) ARRMA® 4S-capable BLX120 Electronic Speed Control (installed)</li> <li>(1) ARRMA® 4S-capable BLX3668 Brushless Motor (installed)</li> <li>(1) Spektrum STX2® Transmitter</li> <li>(1) Product Manual</li> </ul> <p>Needed to Complete:</p> <ul> <li>(1) 3S-4S or (2) 2S LiPo batteries with EC5™ or IC5™ connector</li> <li>(1) Compatible Battery Charger</li> <li>(4) AA batteries for Transmitter</li> </ul>
