Seriously stout 3" motors. I run these on 4S with Gemfan 3052F triblade props, and this setup has me on pace with 5" quads. I know that sort of hyperbole is used quite often, but I can immediately be on the same second on small tracks with this setup.
Efficiency is actually quite good, even when loaded down with 4S 850mAh packs. Hover time on 550mAH and 650mAH packs is still pretty excellent, even on slightly porky builds.
I can't wait for the gunmetal grey version of this motor, because it's really good. I'm definitely getting another set.
