If you want to design another 'Home Depot' plane, you need to start by spending a day in a Home depot and see what they have that might be usable. Then you will need to design around that. I believe that stuff like lumber is regional. In my neck of the woods, they and Lowes carry some usable looking white pine and tulip poplar. But, they are not very long lengths. Plywood is mostly not a high grade, so probably a dangerous structural choice without a large safety factor and bulletproof water protection. I've noticed that their pink foam is 15psi for the thinner stuff, 25psi for the 2". Next year, that may be different... Lowes used to carry Dow blue, but now carry Kingspan, which isn't as good for aircraft. Five years ago, Lowes had a lot of clear white spruce lumber, which I haven't seen since. I should have bought a load and stashed it...Hey yall, I'm currently designing a mid to low wing, wood-fabric ultralight. Goal of this ultralight is to be easily disassemblable (so it can fit in your garage or pickup) and as easy to build as possible. If all goes well, I intend to release plans so anyone that wants to fly, but can't drop five or six figures on an LSA or Cessna, can drop a grand or two at Home Depot and end up with a functional flyer within a few months of on and off wood working. Here's the fuselage and tail skeleton I have so far:View attachment 85199
I'd love to hear your opinions on this and my future work's structural stability and manufacturability.
A grand or two seems rather optimistic. You'll need an engine, too!
