Download the free Spektrum™ Dashboard App to your mobile device to view 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.

Overview

Bigger than big and engineered for brute power and toughness, the ARRMA® 1/5 scale KRATON™ 8S BLX 4WD Speed Monster Truck takes your bashing ability to the next level. Its metal-reinforced design lets you blast up, over, and through bruising obstacles without worry. Metal shafts, turnbuckles and outdrives, plus all-metal internal gears, give the drivetrain and suspension system unstoppable strength. The anodized aluminum chassis plate features composite side pods and a triangular center brace for maximum durability. Ultra-thick composite front and rear shock towers hold massive 20mm bore, oil-filled adjustable shocks that soak-up bumps and jolts.

The power that sends the KRATON™ 8S BLX 4WD Speed Monster Truck charging easily over challenging terrain comes from its 1250Kv Spektrum™ Firma™ brushless motor. The torque and acceleration is incredible. For quick access, the motor is mounted with three bolts onto a sliding aluminum mount.

The waterproof electronics module — also designed for easy access — houses and protects more innovative Spektrum™ equipment. ARRMA® has equipped the KRATON™ 8S BLX 4WD Speed Monster Truck with a state-of-the-art Firma™ Smart 160A ESC and SR6100AT AVC® (Active Vehicle Control®) receiver. Innovative connectivity enables all the Smart electronics to send valuable telemetry data to the included Spektrum™ DX2E Active® transmitter without requiring multiple wires, sensors, modules and links. Just download the free Spektrum™ Dashboard App to your mobile device, which connects wirelessly via Bluetooth to the DX2E transmitter. Then you can view motor RPM, ESC temperature, receiver voltage, drive pack voltage and more data in real-time.

The ultra-tough KRATON™ truck body with high-downforce wing is available factory trimmed, painted and decaled in two striking color schemes. A center protection tower on the chassis interfaces with the roll cage for increased body durability. It all rides on multi-split spoke wheels with strong, durable aluminum wheel hubs, and multi-terrain dBoots® COPPERHEAD™ 2 SB tires with a tread pattern designed for extreme, all-terrain action.
