I like the older kits. Too much plastic in the newer ones. I remember building the Sig Skybolt with the plastic turtledeck. Nice plane but I was forever wishing I had scrapped that plastic trutledeck.
Actually , I'm scratch building more often these days... it's getting harder to find kits for the planes I gravitate toward, especially in the scale I want to build. My latest project is a Beechcraft Staggerwing C17. I haven't decided on scale, I'm drawing to 30% but I may reduce this to 25 since I realized how difficult ($) she will be to ship to contests.
