I came across this motor: http://www.unitedhobbies.com/unitedhobbies/store/uh_viewItem.asp?idProduct=2044 , and wonder if it would be suitable for the Hurricane 550. The price is certainly right. What kind of pinion and gear do I need for a 1345 kV motor on 2x3S packs? Target headspeed around 2000 RPM. Any ideas about flight times with this set-up?

Using the readyheli headspeed calculator (http://www.readyheli.com/Online_Headspeed_Calculator_s/81.htm), I'd say use 14/61 to get around 2000rpm. Looking at the test results for that motor, I see that it draws an ~30A on 6S. So using 2000mAh packs, discharging only 80%, will get you about 3.5 mins of flight...
It's an innerrunner by the way, I'm not sure what the real difference is to outerrunner motors which are mainly used in helies.
