For more than a decade Castle has been providing award winning brushless sensorless motors to R/C enthusiasts worldwide. In response to overwhelming requests by our customers, we have brought technological advancements together that will deliver unprecedented performance in our new SENSORED motor Line. Drivers in all applications demand clean starts when coming off the line. Crawler fans require high-precision low speed control and torque for climbing, racers need precision and predictability, and dragsters don"t have a millisecond to spare. Sensored brushless motors always know the position of the rotor, which eliminates cogging during the startup condition.

Many customers have utilized our industry leading software functionality that *Castle Link offers. When paired with a Castle Creations sensor supported ESC, like the MAMBA MAX PRO or MAMBA MONSTER X, you can unlock advanced tuning capabilities that Castle Link provides specifically for sensored motors. SMARTSENSE^™ uses the motors sensors to start the motor to provide excellent torque and low-speed drivability. Once the motor is turning it seamlessly transitions to Castle's ULTRA- EFFICIENT sensorless mode. As the motor enters distinct phases or transitions to different load points, a different timing advance is required for optimal efficiency. Using mechanical sensors alone, you can only target one individual phase or load point, such as higher start power or higher top end speed. This sacrifices performance and efficiency during the other phases. Electronic timing in SMARTSENSE^™ will advance timing automatically for peak performance during all phases.
