I designed and built a light plane (similar in proportion to a quickie 500, but flat bottomed airfoil and lighter). I had planned on using a 19 turn speed 600 motor with 7-SC cells. What prop/gear box should I use? Will I be able to get enough power to make the plane fly well? What size plane and box are speed 600 (550) motors used on?

I appreciate any help.
