Good motors for 2" and 2.5" props. They seem to handle 3s fine as well and have tons of power even on 2s. Take care when installing props that have a small center hole, they can push the shaft out of the bell of you're not careful. If your props are tight, run a slightly larger drill bit through them or support the shaft from the backside of the motor when you push them on. They come stock on the 110GT, but they work well on any 80-130mm quadcopter. I recommend 12a or higher ESC if you plan to run 3S, on 2S you only need about 10a.
