Since Wicks has decided to only carry plywood now I'm not willing to pay the outrageous prices that Aircraft Spruce wants for its wood.
Longerons and spars will be spruce but I'm changing to white pine for the rest of my build.
I can't find a formula to calculate the sizing of the white pine.
If white pine is 85-95% the strength of spruce what is the formula to calculate the increase in size?
Is it as simple as adding 5-15% to the size of the white pine to equal spruce strength?
