I got this motor used from a friend who bought it from UH. So far, I've run it on a 3S 2200mah, 14x10 prop. This resulted in about 3440 rpm @ 15A. I had to approx the pull, putting it between 1000-1100g. Since this motor can handle more cells and likely a bigger prop, it can really haul a 32oz 3D setup around the sky! Hovering is not a problem even with 3S.
