Whoa! That's high! EDF stuff.

Check out the e-flite heli power 25 - might be overkill but it has a nice fan in it and is high KV - can't remember how much. Otherwise look into a 15-12 equivalent. About 2000 kV should do nicely, just look it up on the Electrifly Rimfire calculator website for example for the prop you want to spin.
