Should anyone reading this be waiting for their own empennage kit to arrive here are the sub-kit sizes as I received them. I took this list to Walmart with me to shop for plastic bins to store the smaller parts in until needed:
1 - 17″x8″x4″
2 - 36″x8″x4″
3 - 35″x22″x2″
4 - 25″x4″x4″
5 - 28″x3″x6″
6 - 96″x3″x6″
7 - 29″x9″x4″
8 - 134″x2.5″x3.5″
9 - 8″x4.5″x5.5″
I tried to store pieces as organized in sub kits. That way when I need a part i can look it up on the packing list (which is organized by sub kit) and know which bin it should be in. I labeled all the bins using a Brother label maker. I am not far into the project, but so far the system has worked great.
