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".
