Arrma Kraton 4x4 4S BLX Monster Truck RTR

#ARA102690 Product Description

ARRMA® created the KRATONT 6S BLX for monster speed and fun. Now comes the KRATONT 4X4 4S BLX - smaller but still intimidating, and capable of 50+ mph speed. If you're looking to level up from brushed power or just want a new ARRMA® experience, unleash the KRATONT!

Powered by the BLX120 brushless system, the KRATONT 4X4 4S BLX is unstoppable on trails, race tracks, and muddy courses. Its 2400Kv brushless motor is matched to an ESC with dual EC5T connectors for using two 2S LiPo batteries. Differential gears inside the front and rear gearboxes are made of durable metal.

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 moulded 16mm Big Bore shocks include top-loading springs and moulded-in shock rod ends to prevent spring loss.

The body has the same aggressive styling as that of the KRATONT 6S BLX, with a smaller version of its rear wing. There are also many subtle tweaks that give the KRATONT 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 tyres.

Included with the ready-to-run package is a SpektrumT 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.
