Welcome to my review of the Wltoys Racerstar 3660 Brushless Motor 60A ESC Waterproof set designed for use in RC cars such as the Wltoys 104001 and 104002. As an avid RC car enthusiast, I'm excited to share my thoughts on this product.

One of the most impressive aspects of this set is the 4 Pole 12 Slot Hi-torque Motor Design which maximizes efficiency and ensures a powerful performance. The CNC Machined 6061 T6 Billet Aluminum Heatsink Can keeps the motor cool during operation, while the High RPM ABEC5 Oversized Bearings ensure smooth movement. The ESC, which is waterproof, allows for a universal fit and features a multi-mounting system for M3 screws. Additionally the M0.6 Metal Gears provide reliable power transfer and durability. Overall, this set offers exceptional performance and reliability for RC car enthusiasts.

One potential drawback to keep in mind is that the motor can become hot during use on a 3S battery as noted in some customer reviews. Additionally, some customers have reported issues with the ESC, such as it failing after a short period of use. However, it's important to note that many customers have had positive experiences with this set praising its strong motor and waterproof ESC.

Overall I would highly recommend the Wltoys Racerstar 3660 Brushless Motor 60A ESC Waterproof set for RC car enthusiasts looking for a reliable and powerful option for their 1/10 brushless car. Despite some potential issues, this set is a top performer with impressive features such as the 4 Pole 12 Slot Hi-torque Motor Design and waterproof ESC. If you're in the market for a new motor and ESC set, this one is definitely worth considering.
