Wooden skewers plane

Something my boys and their friends had some fun with for several hours over days - constantly optimizing and changing things and learn about center of gravity, lightweight construction etc. E.g. they found out that the fin is far too heavy and too thick :-)
To my shame I didn't take pictures of the results...

To build:
Just 3dprint the parts and use some wooden skewers to connect them (the 3mm BBQ-things - larger diameter than toothpicks). Use light paper to cover the wings. Adjust CoG via
