101 is shown as directed leftwards of the direction of wind travel 110 in fig1 and 18 because the points of support of the connector strips 35 and 36 on nail shafts 81 and 82 respectively are widely spaced from the exterior face of the discs 27 and 28 the cords 37 and 38 develop large acute angles as 117 between cords as 37 and 38 and the axis 29 without however any contact between the connector strips 35 and 36 and the disc edges 155 and 106 of discs 27 and 28 respectively when a angle 117 is developed between axis 29 with connector strips 35 and 36 b angle 115 is then also developed between cords 37 and 38 and the central line or axis of the straight rigid cylindrical control rod or stick 39 to which such control cords are attached angles 115 and 117 are the same because cords 37 and 38 are at the same distance from each other at stick 39 as such control cords are from each other where they are attached to connectors 35 and 36 and the same distance is provided between the pivotal and rotatable attachment of connectors 35 and 36 to the nails 33 and 34 because of the large surface area of the discs 27 and 28 the axis 29 of the kite 25 rapidly pivots relative to the direction of travel 111 of the gust 101 to a position of kite 25 as shown in fig1 usually well before the angle 117 of the cords 37 and 38.
