So i did some work on the wing last night. Instead of using 1/16 balsa i used popsicle sticks. And this wing is SOLID. i dont think ill even have to worry about twisting when covering. So the spruce spar i accidently used i think im gunna laminate two 1/8 balsa sticks and using it instead, yes the balsa sticks wont have the strength that the spruce spar would but i dont think itl be too big a problem considering the (popsicle stick) mod i did. any opinions on this? i dont wanna spend 20$ in balsa for ONE spruce spar...
