Very nice plans to make a smallish Predator out of bluecore foam. Too small for a decent UAV (and as we've said here many times, Predators are not the best flyers, being both short-coupled and prone to twitchy pitch, and vulnerable to tip-stalling on landing). But if you want to scale this up, these plans are excellent and would be a good place to start.
