I'm a little ambivalent right now. Flip-flopping between 1900kv and 1700kv, and then I saw some guy over on oople who ran a 1600 outtrunner in his 8ight. It's mostly for the weight savings, that Castle Neu 1717 1Y is a heavy beast.

I have it down to 85% EPA, making it equivalent to a 1900kv motor. It barely breaks 60c after 20 minutes.
