Maximum Wing loading including canard.. (lb/ft2) = 24 Area (ft2) 123.785, Span 32
My first full size project.
Well, I don't know you so maybe your uncle is Mr. Boeing and you have access to a fully equipped CNC/composites shop and a crew to help you but if you're asking basic questions like this, I doubt it.
You noticed that they guy in those videos has a several helpers and they all work like this is not their first full sized project. What you want to eat is a huge schnitzel. Do you know that carbon fiber is around $35.00 per yard vs. maybe $7 for fiberglass? Are you ready to put $100K into an unproven design?
Why not build something from plans--a Cozy, Open-EZ, a Vans airplane, even a Pietenpol--and see what's involved. I have built a Cozy and an EZ and most of a BD-5. You might be amazed at the time and head-scratching it takes to complete a full-sized airplane but the advantage is that when it's done you know it's going to be safe and flyable (except for the BD!).
And it sounds like you want to build a new canard design which is one of the tricky designs to make work properly. You could build this thing over 15 years and find that it's unsafe to fly or requires 100 lbs of lead shot in the nose to make it safe. The homebuilt world is littered with half-done projects. Unless you complete your design, it will not be marketable. Nobody wants to buy a half-finished mystery design.
Pardon me if I assume too much but I say this as friend with a tiny bit of experience. Good luck.
