It seems like everywhere I go to fly I get questions about rubber strip
width. Sometimes I look back at some of my old data or find some old motors
that are described by strip width and have no idea what it means. Using
density to describe motors seems to be slow to catch on but it's really the
only way that makes sense if you fly on competition.
