Series I: Model Engineering Reports Series III: Engineering documents
Series II: Engineering Reports

This series includes 459 reports dated from 1928 through 1947 that were filed under the model aircraft type. There are a couple of idiosyncracies in the Waco use of model names for report titles. The term "various" was used for reports referring to more than one aircraft and the term "All" was used for reports referring to all Waco models. The following reports of this series are ordered alphabetically by model type.
