    It's used in boats, those that want to have the luxury of a "No Wood to Rot" boat will be using Coosa board for the transom, seats and stringers and any core where they would normally be using some sort of plywood.

    How does it compare to the plywood specified in the plans on strength in various directions as well as in various modulii? If it is close on strength and stiffness and on bonding via the methods used in the airplane, it might work. I do not like introducing uncertainties like this...

    My standard commentary is "Stick to the plans unless you are have both a known issue and a known good fix". The build community for each design has lots of knowledge on these topics. Rolling your own modifications is fraught with peril. Build to plans and you will get few surprises of the bad kind. Building to the plans and getting to fly it is a big job and a huge accomplishment. Adding in re-designing and re-engineering the thing too just raises the likelihood it will all end as scrap.
