More likely the builder was using a quirk in the California personal property
law that exempts aircraft with fewer than 5 per model from tax. Simply changing
a letter when you register the model insures that there will be less than 5. It
is quite commonly done.

Since the builder listed it as a "QZ" he may have designed in some
-changes.
