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. |

RCSD ARCHIVE | PDFs of all RCSD and newRCSD
issues can be downloaded from the RCSD archive. This archive is
organized by year, 1984-2018, and issues can be downloaded
individually. Those who desire to download the entire
collection in one ZIPped file can do so by clicking on
this link. |

TWITT Archive |
TWITT (The Wing Is The Thing) came into
being in June 1986 at Gillespie Field in El Cajon,
California, as the brainchild of co-founders Bob Fronius,
Marc de Piolenc, Richard Miller and Hernan Posnansky.
Members included such notables as Dr. Karl Nickel, Peter
Selinger, Reinhold Stadler, Don Mitchell, Al Backstrom,
Bruce Carmichael and Dr. Paul MacCready. Guest speakers
included: Dr. Paul MacCready, Jack Lambie, Bruce
Carmichael, Karl Sanders, Kermit Van Every, Bruce Hinds
(B-2 Test Pilot), Barnaby Wainfan (
FMX-4 Facetmobile
), Al Bowers (NASA Chief Engineer) and Irv Culver (Culver
Twist). This is the official archive of the TWITT website, complete with downloadable PDFs of all published Newsletters. During its tenure, the TWITT website offered VHS videotapes and other materials for sale. The goal is to convert these videotapes and printed materials to digital formats that can be readily downloaded from the archive. Our sincere thanks to Nikolas Korakis for examining the entire archive, notifying us of internal errors, and making suggestions for improvement. Additionally, Nikolas provided several contemporary items which he felt should be added to the archive. This page lists these materials, along with links to the individual items. |

RCSD Special Publications and
Preprints |
The dynamic
soaring of salmon. How salmon gain
upstream thrust from pressure gradients and extract energy
from velocity shears. Plus other strategies for upstream
energy minimization. Authored by Philip Randolph Patten. This
is a preprint, for more information on this technical
format see this
page. Isaac NewtonÕs falsely dismissed theory of inertially caused pressure resistance. NewtonÕs theory vs. dÕAlembertÕs paradox, each correct within differing conditions not knowable in the 18th century. 42 pages, 20,571 words. Authored by Philip Randolph Patten. This is a preprint, for more information on this technical format see this page. Isaac Newton's theory of inertially caused pressure resistance, reinstated. Flow separations and instability drag as the mechanisms of NewtonÕs theory and the theoryÕs defeat by dÕAlembertÕs paradox, each correct within conditions only differentiated in the 19th century. An amusingly convoluted history. 14 pages, 5474 words (plus endnotes). This is a shortened version of the above aimed at journal publication. Authored by Philip Randolph Patten. This is a preprint, for more information on this technical format see this page. |

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. |

FFA DIAMANT Archive |
RC Soaring Digest / B2Streamlines is pleased to be able to make available the DIAMANT Archive containing materials belonging to Art T. Babiarz, Jr., owner and caretaker of Flug- und- Fahrzeugwerke AG DIAMANT 16.5, serial number 012, N1193, XX. This vast amount of material is more than likely the largest collection of DIAMANT information in existence. | |
