I'm looking for information on the Thermic series model gliders sold in the 1940's. They were sold by Model Aircraft Control Co. The name F. Ziac is shown as the designer. I have a Thermic 100 I am rebuilding as a 2-axis RC. Thank you, Tom Johnson RCSE-List facilities provided by Model Airplane News. Send "subscribe" and "unsubscribe" requests to [EMAIL PROTECTED]
