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 sailpane 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.
