Function: 1 PREMIUM MATERIALS: The sensored brushless motor is made of a unique skeleton design, lightweight and high strength 7057 aluminum alloy housing with excellent heat dissipation. 2. PERFECT COMPATIBILITY: Brushless motor with RC sensor, adopts standard 380 size, M3‑16mm(0.63in)/19mm/0.75in mounting pitch, 3.175mm/0.13in shaft, suitable for 1/12 and 1/14 scale RC cars. 3 HIGH EFFICIENCY: RC car brushless motor features original 1EI / AIW (H) copper wire winding with very low internal resistance, and super strong magnetic resistant high temperature EH rated rotors that provide high efficiency energy output. 4 Excellent Performance: Brushless motor with RC sensor has a powerful motor with precision bearings for stable reliable operation and high twisting. 5 HIGH TEMPERATURE RESISTANT: The brushless motor with RC model sensor features a unique gold-plated thick ABC wire brass to allow you to operate freely at temperatures up to 150°C. How to Use: Installation and Link: 1 Motor mounting screw holes for 6 M3 size screws to attach motor, 16mm/0.63in and 19mm/0.75in mounting hole pitch, panel screw hole can be locked to 5mm/0.2in depth, so it is recommended not to use any more. You can decide the installation according to the frame 2. 3 connecting wires need to be welded to the motor. &nb
