They must have been tempted to write "Kamikaze drones". Anyway, interesting development, I wonder why it hasn't been popular to use cardboard so far. Maybe cardboard weighs more, cutting in to payload capability? | |||||||||||||||||

Cardboard is heavy and not very strong. Quadcopter drones carry their payload all by the motors' thrust, and experience large accelerations; they would break if made out of cardboard. OTOH small airplanes like the one pictured derive most of their lift from wings, and are not expected to do aerobatic, so they have somehow lower requirements for strength, and cost considerations can take over. I wonder what would be the military usefulness of such a drone: it's much more visible, likely has rather low payload capacity, and cannot hover. It could work as a recon drone, or a retransmitter for extending communications range. It may be significantly more quiet than a quadcopter, it could even glide with the motor off, so it could sneak towards manned positions, especially in the dark. | |||||||||||||||||

The airframe isn't the main cost driver for these things and cardboard is aerodynamically inefficient. You could blow mould or a million other techniques and get a better, possibly cheaper airframe. | |||||||||||||||||
