MJX Hyper Go H12Y 1:12 4WD FOC Brushless RC Crawler (RTR)

The MJX Hyper Go H12Y is a rugged 1:12-scale 4WD brushless rock crawler built for serious off-road climbing and bashing. Power comes from a 3650 3500KV sensorless brushless motor and a 45A waterproof ESC (E45M), driving a mainly-metal transmission with front and rear portal axles for extra ground clearance. A high-torque 20 kg metal-gear steering servo, adjustable aluminium spring-damper suspension and metal oil-filled shocks let it crawl over rocks and rough terrain with confidence. The aluminium alloy body shell mounts with magnets for quick battery access, and the Tx-controlled LED lights keep it going after dark. Runs a 2S 7.4V 2000mAh Li-ion pack for up to ~45 minutes, with a 4-channel 2.4GHz pistol-grip radio good to 120 metres. Measures 390 × 205 × 185 mm on 90 mm studded crawler tyres. Ready-to-Run, tough out of the box.
