KKPIT RTS-X 3660 3800KV Brushless Motor Waterproof & Dustproof for 1/10 RC Cars

RTS X-Series – High-End Sensorless Brushless Motor Born for the Extreme

The RTS X-Series motor is designed for uncompromising performance in 1/10 scale RC vehicles such as short course trucks, off-road buggies, truggies, and monster trucks. With 220°C high-temperature enameled wire, a reinforced explosion-proof rotor, and an ultra-high slot fill design, the motor core is virtually indestructible. A CNC-machined aluminum housing with high-density cooling fins improves heat dissipation efficiency by up to 30%, ensuring continuous peak power.

Unlike low-cost direct wiring, the X-Series employs thick copper terminals and high-temperature silicone wires for superior conductivity and reliability. Every detail is optimized to deliver an ultimate power experience under extreme conditions.

Performance Advantages

• High-temperature wire withstands 220°C, a 46.6% improvement over conventional 150°C wires.
