If you drop it in vacuum it falls straight down. If you drop it in
air you may get aerodyanmic effects that depend on the shape and
orientation of the gyroscope.

Furthermore there are empirical effects
more than "Magnus Effect" that make for
"weight" something like "heft" that make
for simple real space contraction in effect,
in the classical, as with regards to what
Sedov calls "gyroscopic" effects, for example
in footballs, bullets, and golf balls
(and cars).
The "Magnus Effect" is "well-known", and it's
also "well-known" that the Magnus effect does
not include all the empirical effect due the
rotational, and as to why the linear and rotational
are different with regards to kinetics and kinematics.
So, "Newton's zero-eth" laws with regards to the
vis-motrix, then vis-viva and vis-insita, make
for that classical mechanics is a bit woefully underserved.
The "severe abstraction" of the "mechanical reduction"
is a bit let out, though it's reasonable in the linear,
simply that all kinematics are nominally un-linear.
