When I was very young, I once built a 1.3m wide model plane with wood and thin paper. I even crafted its propeller from a piece of wood using only a knife, a file, and some sand paper. It was powered by a 2.5 c.c. two stroke piston engine. My buddy built a radio remote control system used to command it out of transistors and some industry waste materials. The plane flew half a dozen times before crashed.
These days kids make model planes from pre-assembled blocks. It's no fun at all.
