Let the building begin!

Today, my first kit arrived—3 weeks and twelve-hundred dollars later! I believe this kit contains all the wood necessary to build both the upper and lower wings. I'm going to need some luck figuring out what all the pieces are for. The spars are obvious. I think I know which pieces are the spars for the ailerons. I've got an idea which pieces to use for all the rib bracing. However, there are lots of other pieces and several sheets of plywood. I hope the instructions and plans shed some light on what's what.

These are the four boxes that arrived today.

These are the contents of the four boxes:
plywood, epoxy, spars, and tons of smaller pieces of wood.
