[quote=Rolf_Nilsen]Hmm, alu wings. When will we see new planes with wood structural components?

Wood is not a bad material either. A wood/carbon laminate can be really, really, good in boats.
Rolf, I know you were joking but in fact there are quite a few hombuilt racing and aerobatic planes with wings made of wood as it is lighter, stiffer and easier to work with than just about anything else.
