But you do not fly by stretching, you fly by winding. As the strands are
stripped finer the cross section of the motor in question assumes a more
perfectly cylindrical cross section as opposed to a rectangular one, which will
develop higher torque since it's further away from the neutral point. Ciao,

Opinion: Since we are stretching rubber lengthwise and not widthwise, there is
no difference in turns per inch to be had in thinner strips of equal lengths.
The pro rubber testers have for decades treated the stretch ratio of rubber to
be the same as turns per inch. For rubber to acquire "more winds", one would
have to claim that 2 strands of 1/8" yields a different stretch ratio than 1
strand of 1/4".
