Hi Jure,
Very interesting. I have, or had, the majority of the books you mentioned here. Another great book is Radio Control Slope Soaring. This was our slope soaring bible back in the day when you couldn't find much material on the subject. It's from UK and it's very comprehensive. Though radios have changed since, the basics principals of slope soaring remain the same.

thanks Sean,

the Simons book was your own recommendation to me !

I looked up the book that you mention, and it can be downloaded from here:

Foreword
Before you lie many years of practical, sometimes painful, but mostly great experiences with flying
wing s attempts to connect these experiences with theoretical insights. The goal of this book is to
enable the reader to become wiser from our experiences, to better understand the design of flying
wings and to be able to design, build and fly these gliders.
Many people have contributed to this book, some actively as co-authors (especially Uwe Heuer),
some as proofreaders and sparring partners, and many others who have shared their experiences
with me and tried new things. I have benefited from all of them - thank you very much - without
you, the book would have been much poorer.
If you as a reader perceive something as theft or if you had already tested and discovered it much
earlier, but I forgot to mention it, I apologize (please write to me!). However, theft should be seen
as praise, because apparently, I appreciate that these experiences have helped to clarify certain
things and make the book better. Therefore, I apologize if I present something as new while others
have known it for a long time - in accordance with the motto:
"Whoever believes to have discovered something completely new - this is often rather a sign of
poor research."
Contact me (Peter Wick), so that the next version comes off better and "more correct". I do not see
the book as finished...the idea is that an updated version appears ….sometimes.
To the success of this book, many people have contributed. Uwe Heuer (the Horten chapter and
years of discussions), Tobias Schill (years of discussions and collaborative designs), Joachim
Loerke (feedback on aerodynamics), Jochen Güntzel (on airfoil design, feedback, and collaborative
designs), Rainer Moosmayer (collaborative designs and significant milling work), and many others.
Thank you very much for that.
Enjoy
Peter Wick
