Weight as per my scale: 5,69 grams.
Approx 40 grams thrust at 1,6 amps at 3,77 volts with a balanced GWS 5030 prop and DP3A ESC
(no stabilised power supply, Turnigy wattmeter, 220mA 1S MiniAviation)
This one is in my UMX P40 now. Will order two more for my UMX B-25. One motor came dead, I can buy two of these brushless motors instead of replacing that dead 8.5mm brushed motor :)
Also have some $1,99 3A ESCs from Racerstar that will be used for this one.
This motor with a DP3A ESC and wiring weighs 7 grams or so. The stock 8.5mm brushed geared motor weighs 7,60 approx. So saving weight in an efficient manner.
One issue though: no way of mounting the UMX B-25 or P40 prop.. The shafts are obviously not threaded and no prop saver is included. I'm thinking of hammering our the original shaft and replace it with the UMX threaded shaft..
