Sensorless Brushless Motor for 1:10 on-road and dragster models. Dimensions: 63 mm (L) x 36 mm (Ø). Shaft diameter: 5 mm. No-load RPM per volt: 6500 kV. The open housing design ensures necessary heat dissipation and is ideal for drag racing. The dual-sensor design allows for optimal wiring in the model. Sensor-controlled brushless motors come with an additional sensor cable, enabling fine control and smooth starts. Compared to sensorless motors, they can achieve higher RPMs. A brushless motor is an electric motor without brushes, characterized by higher efficiency, lower wear, and reduced weight.
