I used to just work in Watts and whether the plane needed to go fast or slow. The motor will happily swing a 12in low pitch prop on 3s. You'll get a nice slow flyer with lots of static thrust but not much top end. If you want to fly faster, then go a smaller diameter with a higher pitch. What is the target airframe and flying style for the power train?
