If radar getting you is a problem, for boats they make fairly
compact aluminum "radar reflectors" that are pretty lightweight.
Dunno if they'd fit in a tail section though, kinda
"ship-in-a-bottle" maybe?

I am planning to fit a marine aluminium corner cube into the fuselage
of the Pirat. It's about 12" on each side, very light, and can be
assembled in situ. There more compact reflectors for marine use which
are claimed to have larger radar cross sections, but the emphasis has
to be on "claimed" there.

Active reflectors are also coming in for marine use. They are
not-quite-transponders: when they hear a pulse they send one, or in
some cases several, back. I don't know how compatible they'd be with
airborne radar systems, though.
