Speaking as someone who's built and destroyed lots of homebuilt aircraft, and shot lots of things with guns of various sizes... 1. I think you're conflating "cheap agile drone" with "foam or balsa+durakote fixed wing aircraft". 2. Probable engagement aspect for a drone is not "straight up", as would be necessary for your scenario. 3. A little itty bitty hole in a wing does a whole lot more than you'd think. 4. Expecting a high velocity cannon round to just punch a clean hole in the wing is a little much. Foam's a bit more robust, but a small pebble at a few miles per hour has wrecked my whole durakote day before. And yes, there's degenerate cases, like you could have a whole sheet of dollar tree foam board maybe take a hit or two.
