Skratchbilt, you obviously have a talent and the patience required to work through a challenging kit. My main concern is patience. I have the shop, tools and the internet & acquaintences, but I can picture myself wanting to rush through a particularily mundane part of the build and make a major mistake. Personally speaking, I have a tendancy to quickly get bored with repetitive and mundane tasks. The good news is that I have the time to walk away and come back to it when I feel the itch. I am not on a clock.
I'd love to see more pics of your warbirds. Your Daffy looks great. That bird wasn't very popular in real life terms but I believe it did play a critical, although short role in WWII.
