The radio system also includes an SRX200 2-channel water resistant receiver.
This advanced brand-new RC system launches you into terrain-commanding short course excitement, with difficult elements, amazing 3S BLX power, and premium ARRMA® engineering letting you dominate anything that stands in your course. Precision aluminum, difficult steel and composite materials all combine to make the SENTON™ 4X4 3S BLX a short course vehicle that's ready for hard-hitting action, right out of the box.
Ingeniously developed power, electronics, and differential modules are easy to gain access to and can be gotten rid of from the vehicle quickly for maintenance. They make sure you invest more time bashing and just possible in the workshop. The main differential equipments have been super-sized with big pitch equipments to stand up to big torque. The differential internals feature full-metal straight-cut equipments for equally hassle-free operation.
Independent double wishbone suspension and coil-over oil shocks deal with everything from fast speed runs to snow and mud chucking. No matter where you select to bash, you'll remain steady and in control. The shocks are uncomplicated to maintain, yet use all the efficiency required for amazing all-terrain handling.
High-quality dBoots® FORTRESS SC tires on multi-spoke black chrome surface wheels offer the SENTON™ 4X4 3S BLX outstanding bite on a plethora of surfaces. You can take on any track with self-confidence. The aggressively styled short course truck body — available in green or orange — looks great in action and even much better up-close, where the attention to detail on the decal and body aesthetic appeals really shines.
