Build of 40" BoneYard 5 EPP Finless WIng
I had one sheet of 9mm EPP foam left and wanted to see how big a wing I could build. Note: 1 sheet is large enough for both left and right wing and elevons.
Here is a 40 inch airfoiled wing that comes from a single 600mm by 1000mm sheet (plus using a few scraps to make the spars. I love making these wings, takes about 4 hours and they are virtually indestructable. The hollow wing isn't prone to splitting in half when going into the ground at full speed. Am not using any carbon fiber or additional taping (except for edges) or string - just foam - except for the elevons which are reinforced with bamboo barbeque spits. The end product is laminated with copy shop laminate.
Very strong, can't bend this wing (unless you really really try).
The only problem is that I got in a hurry and made two right wings. Fortunately it is almost symetrical so hopefully will fly ok.
Weight without electrics is 290 grams.
