RE: Handlaunch a Thermic 36?
A picture of the full size sailplane is on page 5 of the first publication. I think it's a Bowlus Super Albatros or Albatros Senior. Zaic and Bowlus were close friends. From other online rememberances it was noted that the first publication of Model Glider Design was finished and published while Frank Zaic was away in the service.
I would upload a picture but RC Universe's image up load applet is being a pickle again.
