At 1/5 scale you are going a bit outside of the typical size for builds here. These are considered "giant scale warbirds" and take an extensive amount of time and money to create. Also note, you posted on Thanksgiving day... most of us here are spending lots of time with family.
Off the top of my head... Jerry Bates has 1/5 plans for the A, B, and C variants. Ziroli also has one as a D model. You can purchase laser cut kits for these at precisioncutkits.com but the sticker shot for just a kit usually scares folks off. For example, the Ziroli kit is $405 + shipping + plans + engine + retracts + servos + on and on and on. This is easily a $1-1.5K project.
Manzano laser has good kits. They feature designs from many folks as well but usually at a smaller scale. Pretty much anything in the .60-.90 size is now usually an ARF or an ebay/swap meet buy.
