Iron: It can be formed into thin steel sheets and tubes that will be stiff enough to keep their shape and light enough to get airborne, although the handful of steel aircraft that have been produced were not famous for their performance. Lead is too dense and insufficiently rigid, and would collapse under its own weight on the runway without ever lifting off.

Iron is better than lead, but ideally I would use aluminum. It's a matter of strength to weight ratios. Lead is soft (not very strong) and extremely heavy, while iron is lighter and stronger, and aluminum, although not quite as strong as iron, is MUCH lighter.

Aluminum, titanium, magnesium, composite fibers, fiberglass, other plastics. Some steel alloys where high strength is needed but in small quantities.
No iron. No lead.

Use iron. Lead is toxic and you will get a lot of flack from environmentalists. Please tell us all when your first flight will be, I'm sure we would all like to see it.

Use a lighter metal such as helium Well it's kind a sort of a metal.
