Sehr laufruhige Motoren, gute Qualität und Verarbeitung.
Der Stromverbrauch ist mit 11" Propellern in Ordnung
Sie sind ihr Geld wert!

These are good-looking motors that run smooth and quiet, delivering very good performance. Tests were done with a Turnigy in-line power meter to measure electrical performance and a digital scale to measure thrust. Battery was a 3s 4500mah 30-50C Nano-Tech. The ESC was a stock Turnigy Plush 30A set for Medium timing. I detected no timing issues. The first test was with a GemfFan 11 x 4.7 SF plastic prop. Measured data was 20.5 amps, 230 watts and 1050 grams thrust. Although that exceeded the rated continuous current of 17 amps the motor did not get more than slightly warm. At 50pcnt it pulled 6.5 amps and 79 watts at 6.2 grams/watt. A second test was done using a GemFan 12 x 4.5 prop. That one pulled 28.0 amps (165pcnt continuous spec) at full throttle with 1100 grams thrust. I aborted the test after about 15 seconds because I smelled the winding varnish cooking and the case was getting hot. It seemed odd that the 12 prop produced just 50 grams of thrust ) more than the 11 at WOT but I ran the tests 3 times to verify the numbers. My guess is that the 12 combination less efficient. At hover (50pcnt) thrust the 11 produced 7 grams/watt while the 12 produced 6 grams/watt. To me the slight gain in thrust is not worth the risk of over-proping.

I put these on my quad, 1.1kg totalt weight. 2200mah 3s 40c zippy. 20A slim afro. I'm very glad with the quality, but after a little flying and some light crashes they make a noise, because of the crashes i can't say it's the bad bearings fault but will change them anyway. got really good "punch" in my quad with a 1:5.5 weight lift ratio. tried these in a rig with 3 different props, and measured power consumption and lift. data:
12x4.5 SF plastic: max 1,3kg thrust and about 230W. at 250g trust it get about 9g/W. 14 min medium wild flight time when consuming 2300mah.
12x5.5 CF T-style prop: max 1,4kg thrust and about 260W. at 250g trust it get about 10g/W. 15 min medium wild flight time
14x4.5 wood: max 1,4kg thrust. at 250g trust it get about 10g/W.

Nice good motors.
Just had today a flight with those motors :
-type hexa
-1x5000mAh 3S batteries
-4220-880Kv x 6
-ESC Afro 30A
-weight RTF : ~2.4Kg
-hover time : 8min

no glitch/sync issues on the motors during the hover.
