"Range 1.03 mm ~ 1.10 mm, but this is not really important for me because
given a constant weight (600mg) and assuming a constant density, the section is
inversely proportional to the length, so when I say 'average' 1.35 mm is just
get a figure."
True enough, but the cross section determines where the level flight torque
will fall on your torque curve. Once that point is fit by correct cross
section, the length determines the total energy required to make the flight
trajectory reach the ceiling. Whether you measure the cross section by measuring
width and thickness or by measuring density, weight and length, it must be
known. If all of your rubber is of the same thickness, width of strip can
stand in for cross section for purposes of matching torque points to cross
section.
