Firefly Revisited


 

Wing assembling

I have discarded the removable Tail Structure due to its flimsyness, but you can contact me if you want to build like that, i still got those files.

Watch the video to understand how to build the Wings. I used very heavy 2mm Balsasheets to build a sturdy Plane but if you want it lightweight, you might change that.
