Oooh, 3100kv! Perfect for me.

IMO, the 2300kv 70mm would be perfect. Otherwise, the 2200kv 60mm would be my next choice. Actually, you might think this is crazy, but the 3100 60mm on 4s geared down would probably work quite well too. Yeah, it would be spinning close to 46k rpm, but that should be just fine. Would be taking a page out of Novaks book (use a smaller motor that revs high instead of a larger lower-revving motor). Might want to check Griffins motor calc to see where the efficiency starts falling.
