After 35 years and more than 400 issues, the December 2018 edition of RC Soaring Digest was the last to be published.

The RCSD Archives contain downloadable PDFs of all of the issues starting with the first from January 1984. These Archives will be readily available for the foreseeable future.

We highly recommend RCSD PDF files be downloaded to your computer HD/SSD where they can be opened with Acrobat Reader 5 or higher. Viewing the PDF within a web browser via a plug-in is not reliable.

Martin Simons'
Understanding
Thermal Soaring
Sailplanes
Walter Jaburek of Vienna Austria has scanned the complete Understanding Thermal Soaring Sailplanes series written by Martin Simons and created a single PDF which includes all of the articles. This series of articles appeared in RCSD starting in January 1990 and ending in the November 1991 issue. There are direct references to F3J, which had just been made an official event but the topics covered are easily related to all forms of RC soaring. Topics include the sailplane polar, weight and ballast, turning,drag, scale effects, performance calculation, moment arms and tail volumes, and horizontal stabilizer considerations, along with numerous others. Well worth the 5.6MB download.

Babiarz, Jr., owner and caretaker of Flug- und- Fahrzeugwerke AG DIAMANT 16.5, serial number 012, N1193, XX.
