I've flown motors from 2206, 2207, 2306, 2207.5, 2307, 2208, etc. This motors are a league above. I used to prefer 2306 1750kv for its low end resolution and improved cooling over 22xx stator sizes. However, that kv lacked top end punch. The 25mm motors have the same low end resolution, plus way more top end speed. Cooling is significantly better than 23xx. Some claim these motors are unresponsive and unfit for 5in, but I firmly disagree. The only factor left untested is durability. I have yet to break one, but I haven't had them for too long yet
