wing and all attached elements (Gurney flaps or any other aerodynamic attachments) must, along its full length and at any
individual measurement point, be fully contained by a rectangle measuring 6 inches by 12 inches. This measurement is to be
made approximately parallel to the centerline of the chassis; the measurement rectangle is not required to be parallel to the
ground. Wing support posts that serve no other purpose shall be exempt from this measurement. to fit in a rectangle of 6 inchheight by 12 inch length a As viewed from the side., end plates must fit in be able to pass through a box 14-inches square. This
