The CNC cut aluminum skin for the top of the rear fuselage of our aluminum ultralight aircraft was ready to install today. The entire weight of the top skin is less than 1.5 pounds!
It didn’t take long, and it was clecoed in place. It still needs quite a bit of work, but it is sure fun to look at.
The front compartment is for the fuel tank and baggage, and has a square cutout with radiused corners. The rear sections are cut out with ellipses to save weight.
Enjoy the picture of work in progress: (Sharp eyes may notice other interesting things in the room…)
