what to use for main spars?
Just thought I would get some ideas of what some are using for mainspars for scratch built airplanes. I have looked at many kits and some use balsa, basswood, and spruce. I will be able to cut spars on a band saw out of wood from the local lumber store however I would be looking at birch, maple, mahagany, and other similar hardwoods. Are these woods used commonly for spars or do I need to break down and order some large chunks of basswood or spruce.
Thanks for any comments,
John
