For sale is the small Ok-C2830-24 Out Runner Brushless Motor. I don't know much about this. I'm not able to turn its output shaft(maybe that's normal).  Per spec sheet: voltage range is 6-12V, pull is 300-650 g, weight is 58g, ESC is 20A, motor has big torque, with small noise, super efficient and efficiency can reach 87%. Sold as is.No returns.  Thanks for looking.
