Pippo,
Crudely estimated slab volume from plans as 0.0166 m^3. This would
give a density of about 11 g/cm3.
Do you have any info on the aluminum tubing/pipe used in the Navigator
version of Micro?

Just curious... lead's density is about 11. However, if you consider the
volume of Micro's ballast slab (0.023 m^3) and its specified weight (187
kg), one obtains a density of about 8.2. Where's the trick? Is the
commercially available lead doped with other materials that make it
lighter?
