About this part

Authentic Scale Appearance - Capable Brushless Power

Take on tough terrain with the MJX HYPER GO H12Y 1/12 4WD RTR Rock Crawler. Its sensorless brushless power, metal drivetrain, portal axles, adjustable oil-filled shocks, and scale aluminum hard body deliver a powerful blend of off-road capability, durability, and realistic detail.


About the H12Y Scale Crawler

Scale Trail Performance

The MJX HYPER GO H12Y combines a realistic aluminum hard-body shell, aggressive all-terrain tires, high-clearance portal axles, and front/rear LED lights for capable off-road performance with impressive scale detail. The portal axle design helps increase ground clearance for tackling rocks, obstacles, and uneven terrain. The clipless body mounting system also keeps the exterior clean and scale-focused.

Brushless Power System

Its H12Y sensorless brushless setup pairs a 3650 3500KV motor with a 45A FOC Vector Control ESC for strong, responsive power delivery. The sensorless system provides a simple and durable brushless power solution for tackling trails, rocks, and technical terrain. The waterproof receiver box adds extra protection for off-road driving.

Heavy-Duty Drivetrain

A durable all-metal drivetrain, metal gear axles, nylon gearbox gears, full-metal driveshafts, metal suspension links, and complete ball bearings provide reliable power transfer and smooth operation across demanding terrain. The robust components are built to withstand the added stress of crawling over rocks and obstacles. Ball bearings throughout the vehicle help reduce friction for efficient, consistent drivetrain performance.

Tunable Suspension Performance

Threaded aluminum oil-filled shocks offer adjustable spring travel and damping, while dual tire and spring sets let you customize the crawler's handling. Adjustable shock settings make it easier to tune the suspension for different terrain and driving styles. Combined with the stable suspension design and high-clearance portals, the H12Y is ready for controlled, capable trail performance.
