You can label "Tests results" or how you like, but not compare, it is flawed from the start to compare 850kv with 1130kv with same prop !
Redo test with 9" prop on 20-26 and will see.

First of all: thank you so much for this thread. Really useful for all of us.
I've done enough flying with cheap vibrating motors and have spent enough time trying to balance them. So I want to buy some new better (and more expensive motors). So I'm reading, reading, reading...
But still can't decide. My number one priority is low vibrations. Seems like you've tested a lot of motors. So what are your experience if I want to buy a set of motors that are well balanced out of the box?

I posted this in my Flexacopter topic, but I think here is also a good place for this test.
Today a have done a test with all the props that I have suitable for the Flexacopter, I try to show what prop will give the most smooth image with the current MK gyro settings that still need some tuning.
Flexacopter with in the AV-130 mount the GH2 camera fitted with the Olympus 45 mm F1.8 (90 mm telelens equivalent to 35mm film) (F5.6) 720P/50f-sec.
Total flying weight with the 5S/8000mAh lipo and GH2 4520 grams, Picloc Pro is off so no mount stabilization.
I have also noted the Amp rating from the MK indicated during the hoover with each prop, here the outcome.
Graupner 11x5 E (43A)
APC 12x3.8 SF (41A)
APC 14x4.7 SF (38A)
Xoar 14x5 wood (37A)
Outcome regards the video quality.
Graupner 11 x 5 (E) a clear first place.
APC 12 x 3.8 SF and the Xoar 14x5 2nd and 3rd place
APC 14 x 4.7 SF Gets the fourth place
You see also here no Free-Lunch!!
The Graupner 11x5 does it surprisingly good but has the highest consumption, The Xoar 14x5 is despite his shared 2nd and 3rd place far below the video result of the Graupner props but 6A more economical.
I would clearly indicate that this test outcome regarding the video quality in my situation is no guarantee for the same outcome with an other setup.
The 4 videos,

What motors were used, as it's not clear regarding your previous post?
