Ezrun MAX 4990 SD G2 brushless motor. The waterproof sensor cable and sensored system give smoother acceleration and more power than the prior generation. Built to pair with Hobbywing EZRUN MAX6 G2 or later series ESCs. The ESC recognizes the motor and runs full sensor mode, with finer control and motor overheat protection. An independent high-precision encoder outputs a pure rotor position signal, which keeps sensor interference from affecting the motor. The housing is CNC-machined aluminum. Other parts include high-purity copper windings, an explosion-proof rotor, ultrathin silicon steel laminations, a stainless steel output shaft, and high-precision bearings. The sensor interface and rubber cover bearings offer better waterproof and dustproof protection than traditional sensored motors. WSBLM: Waterproof Sensored Brushless Motor technology. Applications: 1/7th on-road, short course truck, truck, and 1/8th heavy-duty monster truck. FITS: General hobby universal fit car parts
