E-flite BL10 Brushless Outrunner Motor (900kv)

Bought this to install on my Flex-Innovations Extra 300 QQ. Original 3S motor, 1400 Kv only gave 3.5 minutes flight time as usual with that plane. I just changed the motor and went to a 13x6 prop. The result was more power, better hovering but most of all the flight time is constantly about 7 minutes. More if you baby it, less doing 3D all of the flight. I did once get 9 minutes and 10 seconds, came down at about 24% on the Admiral 2200 4S battery. Easily get 6 minutes instead of 3.5 I am very happy with this motor and plan to do the same to my Flex Mamba 10 and my new Extra 300 back here at home. The 2200 4S battery is ideal but I am going to try out a 2600 4S, not much heavier, maybe even more time.
