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

The MJX Hyper Go H12Y+ is the sensored-motor version of MJX’s acclaimed 1:12-scale 4WD brushless crawler — tuned for smoother, more precise low-speed control on technical terrain. It runs a 3650 3500KV sensored brushless motor with a 45A sensored ESC (E45SDMF), giving crawl-perfect throttle response where it matters most. The same tough platform underneath: a mainly-metal drivetrain with front and rear portal axles, a 20 kg metal-gear steering servo, adjustable aluminium spring dampers, and an aluminium alloy body shell that mounts with magnets for fast battery swaps. Tx-controlled LED lights, 90 mm studded tyres and a 2S 7.4V 2000mAh pack for up to ~45 minutes of run time complete the package. Controlled by a 4-channel 2.4GHz pistol-grip radio with 120 m range. Ready-to-Run — the crawler of choice for drivers who value finesse over flat-out speed.
