Okay...so some of you may be aware that I have a math learning disability. It's a weird situation where I can apply theory and figure out interrelations but I repeatedly failed basic algebra etc. Despite having plans to have more experienced folks look over my design before I build my design, I am really leaning towards building a "spare" wing and tail to really test my calculations (plus, it's a "dry run" practice for my building skills). Since these are going to be wooden structures-- only the cockpit (the "shark cage" as my wife calls it)-- is primarily metal, the issue of cost and hassle are somewhat lessened versus metal or composite. Also, working with wood is fun. Plus, I get to break stuff in various ways. That's always a treat. LOL I know this is done with commercially built aircraft but I am curious if any of you all have done this?
