Wing Spar:

The wing spar can be basswood or hard balsa. The dimensions are:

Note: if you cannot source this material at its full length, center a 530 mm length section through the wing assembly and add additional sections at the wingtips. Reinforce these sections on the front and back side with 2mm x 10mm plywood strips.

Creating the left wing:

Simply rinse and repeat. Simply use the mirror function in the Cura software to print mirror copies of all of the wing components as shown below. Both halves are to be bonded by the center rib using CA glue.
