I've always wanted, but never found, a comparison chart of the
three Hatz models, so I decided to put something together. The following
are two charts: first is a specifications chart of the three versions
of the Hatz and second is a chart outlining some of the main
differences between the models. The information came from their respective
websites and as you can see they do not all report the same
information so where you see empty cells, the particular
website did not have any information listed. For
example, the Hatz Biplane Association website listed a
"Landing Speed" for the CB-1, where the Hatz Classic
and Bantam websites listed a "Stall Speed".
Also, the Hatz Bantam site was the only one to list a Vne
speed and "Demonstrated Crosswind"
speed.
Any data
in purple is data I added; either calculated based on other
data already provided by the Hatz websites (like useful load
and range), or obtained from known sources (like fuel burn for
the O-200 and O-320) .
