Over the past couple of weeks, we have started construction on our demo aircraft for this year. Construction began with the 3D printing of the parts for the wing. 

Yesterday, the final parts for the wing came off the printer. 

After a little bit of sanding work to get the parts to fit together, we were able to begin assembling the wing. 

This time next week, we hope to be finishing the wing assembly and attaching it to the fuselage.
