Feature:1. Powerful Tool: Uses ultra large balance 5 slot rotor, the motor will run smoothly and reliably with large torque.2. Hard Outer Shell: With CNC precipitated high hardness steel shell and gold‑plated process, the outer shell can procide efficient protection of inner parts.3. High Performanc: RC crawler motor contains ultra thin (0.35mm) silicon steel sheet stator and wear resistant super large current high quality low resistance carbon brush toprovide a high performance.4. High Tech: Motor has 24K gold plated low internal resisting terminal connection welding piece, also equipped with dual PCB board capacitance to effectively prevent interference.5. Easy to Use: Removable replaceable structure is easy for cleaning and maintenance, specially designed to RC crawler vehicles which needs precise motion control.How to Use:Installation and maintenance:1. Replace the motor mounting screws with the same model and size as your original vehicle.2. Do not tighten the motor mounting screws too much. Doing so may peel off mounting hole threads.3. Connect the + and ‑ motor leads to the corresponding leads on the electronic governor (ESO).4. To adjust the time, loosen the main screw slightly and twist the tail until the desired setting is achieved, then tighten the screw again. Factor
