Inside, the fully simulated Sierra S interior includes a detailed dashboard, gear shifter, and seat texture decals, delivering an immersive and realistic scale experience.

Independent Brushless Power System

Powered by an outrunner brushless motor paired with an independent brushless ESC and a dedicated receiver, this system delivers efficient power output, smooth throttle response, and reliable performance across a wide range of driving conditions.

Simulation Lighting System with Multiple Light Modes

Equipped with headlights, taillights, turn signals, and roof-mounted spotlights, the lighting system delivers multiple realistic lighting effects. Lights are remotely controlled via CH4 channel switching and feature synchronized, interactive functions for enhanced scale realism.

New Portal Axles for Superior Ground Clearance

Front and rear portal axles with wheel-end reduction increase differential ground clearance, significantly improving off-road capability and obstacle-crossing performance on rough, uneven terrain.

Two-Speed Transmission for Strategic Control

The integrated two-speed gearbox allows seamless switching between low-speed crawling and high-speed driving, giving drivers greater control and adaptability across different terrain and driving conditions.

All-Metal Chassis Construction

Built on a high-strength metal chassis with metal frame rails, metal link rods, and metal gears, the Sierra delivers enhanced durability, stability, and long-term reliability under demanding off-road conditions.
