About the Ghost RC 1721 Sensored Brushless Motor
Engineered for Extreme Power
The Ghost RC 1721 2400kV Sensored Brushless Motor is built for serious speed runners and drag racers who demand maximum performance and reliability. Co-developed with Castle, this updated design enhances the legendary 1721 platform with an improved shaft, can, and stainless steel sleeve for superior strength at high RPMs. Designed for up to 8S LiPo power, it delivers explosive acceleration and unbeatable top-end speed for 1/7 and 1/5 scale racing machines.
Precision Built for Performance
Every detail of the Ghost RC 1721 motor is optimized for power and efficiency. The removal of solder tabs reduces resistance for cleaner energy flow and higher output, while the stainless steel wrapped rotor and ultra-balanced shaft ensure smooth operation under extreme loads. When paired with the Cobra 5 ACE system, this motor provides unmatched consistency, torque, and durability — making it the ultimate choice for next-level drag and speed run dominance.
