Default What size motor do I need??????????

Hi,
I am new to electric motors for my planes and I have no idea how to tell just what size motor or ESC to get for a couple of my planes that I would like to convert from fuel to electric. I was told that I should figure about 100 watts per pound Is this right? Please tell me that there is a way to figure out what size motor that I need for my planes? Thank you for your time and trouble.
I was also told that for a 1.5 pound (24 ounce) airplane, in order to get true 3D type performance, you need to be able to generate at least twice as much thrust as the plane weighs, so this would mean 48 ounces of static thrust or more. HELP!!!!!!!!!!!!!!!!!!!!!
