Iwas given a motor(w/gws gear)and esc from an uncles underpowered 3d foamy.Dont know exactly what it is but it works on a 30" p-40 thatI built. It has a two blade gws 9x7.5. Im looking for possibly more ground clearence and a better look. Would it still be a 9x7.5 3 blade or is there some way to figure out the math?</p>
