You asked, and Castle listened! For more than a decade, Castle Creations has been providing award winning brushless sensorless motors to RC enthusiasts worldwide. In response to overwhelming requests from their customers, they have brought technological advancements together that will deliver unprecedented performance in their new sensored motor line. The latest additions are the 1406 series in a Slate color, in 1900kV, 2280kV, 2850kV, and 3800kV. These motors are Rock Ready and Castle has the startup on low RPMs under control. Now you're covered if your looking for ultimate control while out on the trails or on your Ultra 4 track days.
Why sensored? 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. To achieve all of these performance demands and more, Castle has integrated rotor position sensor technology with their improved high-power and high-efficiency motor design. Through the use of sensors, the position of the rotor is always known by the ESC. This eliminates the possibility of encountering cogging or inconsistency during startup. Users will experience precise throttle control and buttery smooth starts plus the raw power and longer run times that Castles highly efficient motors produce.
