For reference, to help anyone looking at buying one of these:

Produces around ~500gms of thrust on 3s, 5550 gemfan prop (on the small side, I needed ground clearance) and a 20A ESC, enough to give my x1 flying wing infinite vertical abilities. Total weight of motor, prop adaptor. ESC, bullet connectors and a plywood mount was 3oz. Runs cool, lukewarm when kept at WOT (static, pusher set up prevented airflow cooling the motor).
