I've always thought that the ideal pure-Lego flywheel would use 4
of the metal counterweight pieces that are sometimes used for the
gates in train crossing sets (and one also came in set 8094 Control
Center too). You could use 4 of them in an 'x' fashion (they have
'+' shaped crossaxle holes for mounting, so it should not be too
hard to come up with a compact, sturdy assembly). Unfortunately,
these are not common, and I don't know if you can get them as spare
parts through DACTA or elsewhere.
