RC enthusiasts, this Surpass RC 3665 brushless motor is a beast of an upgrade for your 1/10 scale truck or buggy. With a 3150KV rating, it delivers serious power (up to 1400W) and torque, making your rig faster and more responsive. It's a sensored motor, meaning it has a built-in temperature sensor and port for smoother low-speed control and better protection against overheating when paired with a compatible ESC. The 4-pole rotor design and high-quality materials – think aluminum CNC case, high-temp copper wires, and sealed bearings – ensure durability and stable performance. The shaft diameter is 5mm, and it features a removable design for easy cleaning and maintenance (just remember to uninstall the cooling fan before using the electric switch, and keep the connector clean and dry). It weighs around 274g and can handle up to 14V and 80A. Perfect for replacing a worn-out motor or giving your RC car that extra edge in speed and reliability. Surpass Hobby is known for genuine, well-made products, and this motor is no exception. Get ready to leave your friends in the dust!
