The sensing tail will have several elements: a small pocket to hold the wireless sensing board, a round tube made of fabric to hold the flow sensor, and ribbons of black conductive foil which form a kind of chaos or air fluctuation sensor.

I try to improve upon the designs of the version of 2012 - by making the pocket out of blue kite fabric, and the round tube out of yellow and red fabric. The black conductive foil is attached to the end of the tube.
