    Nicely made motors that work well on 3s. The product data does not seem to be correct. At 7.4V I get about 65g of thrust at 1.7A. 115g of thrust is about right at 11V

    Брал 6 штук, хорошо что с запасом, из шести только 4 с более менее хорошим балансом. Следы балансировки отсутствуют По качеству исполнения претензий нет Из пожеланий в дальнейшем обязательно балансировать моторы и выводы мотора делать из многожильного провода а то одножильный легко ломается

    For my 110 mm frame pros: Racerstar quality, quite cheap cons: none, 4000KV has low thrust, the quad must be very light

    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..

    The motors work fine but they dont have short screws so you need to buy other ones too mount the motors on your frame. The motors create very small thrust with 2 inch props you are better off with motors with higher kv
