Sitka Spruce commonly used in wing spars, longerons and diagonal braces in fuselages and tail sections, because of it's shock absorbing properties. Spruce although twice as heavy as balsa is ten times stronger. Sitka Spruce has a fine, even texture, and a consistently straight grain. *All orders are double checked off before leaving the facility for straight material however as it is such a natural product if warping should occur during transit we are not responsible for the shipping to replace the material.*
