This is the ZERO-S" series of basic brushless motors for drifting. We also have red and purple anodized colors that have received many requests from users, and the color of the YD-2 series is best matched. Despite its slightly torque output characteristics, it has a smoother throttle feel for low and medium speed control and easier traction control with the RWD drifting from corner ring to straight rise. The motor case has minimal cooling holes to promote critical cooling effect on drift rides, and the center case anodized and beveled edge on the endbell for contrast design. Reasonable pricing with attached connection cord. This basic motor is recommended for everyone from beginners to advanced users.
