In addition, towards the end of the lab lines were added balance the gliding action of the kite. However, it was decided that the final design will not feature this line, as a glider design will be now constructed instead.
The first prototype of the kite was constructed during week two. It is a scaled down version of the final kite design featuring a wooden frame and plastic skin. The kite measures 45.0 cm wide and 29.5 cm long, which is a little less than half scale. A rounded front and back were constructed using metal wire and straw to keep the plastic skin in a curved shape to allow for smoother air flow. The weight of the kite at this point was 12.0 g.
During preliminary testing, the kite stalled (angled upwards), so weight was added using extra wire and paperclips. This added weight moved the center of mass of the kite towards the front, balancing the lift force so that the kite flies steadily. The final mass for the prototype was 19.1 g.
