Came pretty well balanced until fan fall off. This is counter-rotating unit so the nut tends to loose unless you tight it insanely and glue. I guess they couldn't change the thread direction...
Works well and stable on 9S, on 10S smells burning. Have removed cone from the motor as there's no heat paste inbetween. Air comes out pretty warm so the efficiency must be low. On 9s with thrust tube pulls around 100A and motor is around 70 centigrade at the end. So, the power is around 3kW unless you plan to burn it.
