A part of the review has been auto-translated.
Single strand winding, good copper fill, good size curved magnets, very close air gap. Looks very nicely made. Weighs 18.2gm out of the box, comes with 2 o-rings and 2 prop fittings, for 7mm and 8mm bore props. The shaft sticks out the bottom approx 0.9mm and is 4mm diameter. The retaining clip looks like it sits flush with the bottom of the motor so you would want a 9mm hole to flush mount this motor. I gave it 5 stars for now but haven't run it up yet. On the box it says "AS SERIES for the entry level".
Perfect weight, very well packed
Too bad
super products
Awsome purchase, Fast shipping and product as discribed.
I've only used the motor once but it works fine.
Using this motor on a Rc-Factory Click-21 on 2s/200mah with a PT-models 9x2.5prop. Motor is very quiet and smooth. Giving enough power for the Click but in a very smooth way. Really pleased with this one. Also used the hornet 6A ESC with this set... nice combo
good construction quality
Very good
same as sbove
