It's been quite a while since I've been here hasn't it? I haven't done a ton of rc things and I missed ff23 but I have big plan(e)s for next year. I'm thinking of building an ultimate combat plane; the one to beat. So far, my ideas is a scaled up VAS spectre-like design to about 2 meters. Booms are cf rods that hold 4 motors. In other words, I want to make a giant combat quadplane. Any ideas for specific airframe designs for maximum strength and agility? Currently, My idea is to make a 3d printed mould and then form an airframe with carbon fiber, then glue together the pieces to make a hard shell. After that, there will be rods inside for stiffness and then filled with hardware store spray foam for structure. I've been told this carbon shell is not the best for combat, so does anyone else have suggestions?
