In this volume, flap data on four R/C soaring airfoils is presented. This data would not have been taken were it not for the efforts of Jack Spitz and Ernest Trent, Jr. (Design and Manufacturing, Ltd.) who produced the flap endplate brackets used to secure the flaps. Finally, the remaining acknowledgments updated from Volume 2 still apply. Several others (some already acknowledged) deserve special mention. It is with a deep sense of gratitude that we thank Herk Stokely (SoarTech Publications) for his diligent and ongoing efforts related to distributing Airfoils at Low Speeds and now this book. Also, we have been very fortunate to have received a large donation from an anonymous individual to support the purchase of a new computer and additional equipment that has helped to improve and expand the scope of the program. We have benefited greatly from the earlier work of Dr. John Donovan and the late David Fraser, as well as the many other individuals who contributed to the Princeton Tests. The efforts of Cody Robertson in designing the 1994 UIUC LSATs t-shirt is sincerely appreciated. Special thanks are also extended to Karen Evans for her assistance in designing the UIUC LSATs logo. We are also appreciative of Gilbert Morris for organizing the construction of the free flight wind-tunnel models and for providing background information used in the discussion of the F1B airfoils. Also, Lisa Selig's efforts and encouragements are greatly appreciated. Of those at the University of Illinois, we wish to thank Mike Kerho (now at McDonnell Douglas) and Stan Berkovich for their help with the data acquisition software. With respect to digitizing the wind-tunnel models, we thank Prof. Michael Philpott for the use of his coordinate measuring machine and also Stephen Craggs for initial setup support. Andy Broeren especially wishes to acknowledge his research advisor, Prof. Michael Bragg, for his patience and support thoughout the course of this project. We are indebted to Carol Winkler for her efforts in maintaining the mailing lists and processing the donations. It should be mentioned that some of the work reported here has benefited from other research activities, such as research sponsored by the Univerisity of Illinois and also research in wind energy supported by the DOE National Renewable Energy Laboratory. Finally, we must apologize to those whom we have inadvertently omitted.
