Efficiency Champ? Sunnysky x2820 800kv Brushless Motor [The Judge Ep. 6]

UPDATE: There was a typo on the workbook image. SK3 peak amperage with the 11x6 prop was 45.60 not 44.90.
This is the rcvideoreviews.com First Look and Bench Test of the Sunnysky x2820 800kv (3542 / 138 gram) brushless motor.
Here is a link for the motor: sunnyskyusa.co...
I'm evaluating this motor as an alternative to the Extreme Flight RC recommendation for the Vanquish MKII. The SK3 3542 I initially installed on the Vanquish has performed well; however, when I initially started looking at the Vanquish and the supporting equipment this Sunnysky caught my eye. I wanted to compare it to the SK3 for the benefit of the channel.
Sunnysky motors have a reputation out there as being quite efficient. This motor appears to support that point of view.
Bonus: See another APC vs. MAS test.
