Hobbywing Ezrun 4990SD G2 1650kV 4pin, 5mm shaft for 1:6

Sensorless brushless motor for 1:6 scale RC vehicles. Dimensions: 90 mm (L) x 49 mm (Ø). Shaft diameter: 5 mm. No-load RPM per volt: 1650 kV. Ideal as a complement to the EzRun Max6 or Max5 controller for a fully sensor-controlled experience. An independent and highly precise encoder effectively prevents interference from sensor signals. Water and dust resistant according to IP67 standard. Sensored. Sensor-controlled brushless motors feature an additional sensor cable, allowing for fine-tuning and smooth starts. Additionally, they can achieve higher RPMs compared to sensorless motors. Brushless motor. A brushless motor is an electric motor without brushes, which, compared to a brushed motor, offers higher efficiency, less wear, and lower weight.
