I got this motor to replace one in my F-16 (2700kV) that burned out. This motor has made a huge difference in performance. I and others have estimated speeds around 100 knts. This is a great motor. I am using a 60amp esc, and 4S 20C 2200 lipos. I think 25C's would be better though. Excellent Motor for the money.

Motor began to smoke after being run the third time and then froze up. One winding fried, why, I have no idea.
