This is the Castle Creations 1721 1260kV Sensored Brushless Motor. The 1721 is a powerful and efficient motor designed to deliver exceptional speed, torque, and acceleration, making it the perfect choice for serious large-scale bashers who demand nothing but the best. Built with precision-machined components, high-strength magnets, and advanced winding techniques, this motor is engineered to deliver reliable and consistent performance in even the most challenging conditions.

Based off of the high speed 1721-2400kV motor this lower kV option has been designed to offer the incredible torque and cool operation needed to push large scale vehicles to the limit. This makes it the perfect moderate, yet powerful upgrade to the 1717 size motors that come stock in the Traxxas X- Maxx and Arrma 8s vehicles.

Without a robust and reliable design, efficiency will only go so far. RC enthusiasts love pushing their equipment to the edge. The Castle engineers know this and spared no expense when developing a design that could hold up to the harsh conditions that the RC community will throw at it, resulting in a cooler running motor. In the end, the result is a motor with unmatched quality, performance, and reliability. Castle wouldn’t put their name on anything less.

Features:

• Running modes include SmartSense Sensored and an ultra-efficient Sensorless mode.
• High-strength, high-temperature grade neodymium sintered magnets combined with High-strength Kevlar wrap ensures the integrity of the rotor is not compromised during harsh running conditions.
• Oversized NMB bearings and vibration dampening system ensure the longest bearing life possible.
• Proprietary winding techniques allow Castle to produce a stator assembly that is the lowest possible resistance, resulting in a cooler running motor.
• Updated modern and sleek design; looks as cool as it performs.
