You can't touch these for 40 bucks. I have more than 3 dozen flying in a bunch of different frames and NONE have ever failed. Take a 680 pro Tarot frame, 6 of these, 6 opto 45 amp esc's and a 5000 mah nano-tech battery, 14x5.5 props and it gets 19 minutes of time flying, not hovering. Even with a gimbal, it still gets close to 15. It would run much larger props but not on this frame, 14 is it. They will lift most anything and 8 of them on a 1140mm frame makes a super stable photography platform. With a WooKong controller and a decent camera, hollyweird quality pictures. Just right KV for 6S. Runs way under 90 degrees F. Easy on esc's. Work great on a split power system at 8S. So far everything we have tried has worked. I have sunnysky and T-motors as well as DJI, all good, all more expensive and none lasted any longer or performed better. You could say we like these!

I have purchase much more expensive outrunners in the past. Six of these with 16x5.5 props EASILY lifts my 1203mm hex (custom built) at 6.6kg. With 2 Zippy 8000mah batts I get 15 to over 20 mins. of time in the air. I will be testing 4 Turnigy-nano 5000 mah batts. (total weight less than the Zippys). Should get more time in the air. 4 hard test flights and the motors are performing very well. Just slightly warm to the touch after 15 mins.

Very strong motor! Great for big projects using 6s.
The main concern is about the build process. After using this motors I figure out that some vibration sounds that I was listening, is because some washer was not in the right place making the external part of the motor jump up and down causing the noise.
If you have this motor MAKE SURE to check the internal washers. In all of my 6 motors, 5 of them was missing whashers or they were not in the right place!

Two out of four failed within 2 hours of flight. Loose magnets on one and improper shimming on the other. HK is sending me replacements when they get back in stock. When working correctly they can lift a house.
