As stated earlier, Estes and
Centuri made
many parts that are no longer available. This section of the site
is intended to serve as a guide to shapes, sizes, and currently
available
equivalents to these parts that are no longer in production. In some
cases, when this information is readily available elsewhere on the web,
I have provided a link to that location. I welcome any and all
contributions
to this part of the site.
Body
Tubes
Note: This is not a comprehensive list
of body tube sizes, as it is merely intended to give a guide to
currently
available equivalents. For a more complete list of body tube
lengths
and diameters, please refer to Estes
Body Tube and Fin Sizes, on Ninfinger Productions: Model Rockets.
