Prop choice for GAD F-5 and Suppo 2208/14 1450kv motor

Hello all!

I recently built my Green Air Designs F-5 kit (18" wingspan), and have a Suppo 2208/14 1450kv motor sitting around, which seems like it might work with this plane. I was looking at some motor calculations Here, so would a 7x4 be the best choice? I would like unlimited vertical and maximum speed. I don't think the vertical will be a problem, with the plane only weighing 7-9 oz and 3s showing over 19grams (mabe 3s is overkill, it looks like 2 cells will give me over 9g of thrust!! ). Has anyone used this motor? Is there a "magic prop" that was just made for it?
