Martin Simons'
Understanding
Thermal Soaring
Sailplanes

Walter Jaburek of Vienna Austria has scanned the complete Understanding Thermal Soaring Sailplanesseries written by Martin Simons and created a single PDF which includesall of the articles. This series of articles appeared in RCSDstarting in January 1990 and ending in the November 1991 issue. Thereare direct references to F3J, which had just been made an officialevent, but the topics covered are easily related to all forms of RCsoaring. Topics include the sailpane polar, weight and ballast,turning, drag, scale effects, performance calculation, moment arms andtail volumes, and horizontal stabilizer considerations, along withnumerous others. Well worth the 5.6MB download.
