I notice on your poll you are specifying a 10S setup.  I really think you would be better off keeping the plane light by using an 8S setup.  It helps with the downline speed among other things.  The Scorpion motor in the one I have been flying is <font size="2">S 4025-16.  Light, and plenty of power.  You may want to add that option to your poll.</font></p>
