By:team losi
Quantity: Only 1 left in stock.




The Losi® Hammer Rey® is a SMART, Ready-to-Run Rock Racer with AVC®.


It is officially licensed and based off Casey Currie's U4 Racer. It's powered with a Spektrum(TM) 3150Kv brushless motor and managed by the Smart 130A ESC, 6-channel DSMR AVC/telemetry receiver, and the new DX3 transmitter that provides Spektrum Smart feedback including live battery voltage. Along with the officially licensed design, the Hammer Rey includes KMC wheels, Nitto tires, and additional details such as new shock reservoirs, fire extinguishers, and new light bars. It comes equipped with a solid rear axle, independent front suspension, and oil-filled shocks, so you can tear across all types of rocky off-road terrain. And you'll do so with the full-throttle freedom that only AVC® technology can provide. The Hammer Rey is ideal for victory-minded off-road enthusiasts looking for the top-of-the-line RC experience with the inclusion of AVC and the three-position limiting switch. With the Hammer Rey, Losi continues to push the limits when it comes to scale details, performance and officially licensed products.
