I plan to make a very light weight wing out of a light weight wood like spruce, in a muggy, humid environment where it rains often and is 100 degrees outside. It will be light enough that I don't want to spray sealant on the wood because it might make the wing heavier. My goal is a one time use, with construction time estimated at 2 months. My question is, will the wood likely warp or absorb a lot of moisture during those two months, and what can I do to minimize it? Should I try to put air tight skin on the wing to keep moisture out? I'm afraid there will be condensation in there in the morning at flight time, though I really have no idea. I plan to store the sections well supported in a typical storage unit until they are ready for assembly on flight day. I'm talking thin, hollow spars, with high surface area to volume ratio. Thanks.
