After looking at this website, you might get the impression that I have only built corrugated cardboard CL designs during my modeling career.  However, I started out like most oldtimers (I  was born in 1938) building stick, tissue and balsa kit models, mainly control line.  I wasn't introduced to building cardboard models until the mid-1970's.  As evidence, look at the following photos. 

1.  This 1970 photo shows what I called my "Air Force" back in the old days before I began building with cardboard.  It consists of CL kits I built as well as profile CL models I designed of the Yak9 and FW-190.

2.  I subsequently started designing scale CL models using traditional balsa wood and had four of them published as construction articles.  The first was the Ryan Fireball published in M.A.N. in September 1971, Plans no longer available.

After the publication of the above four balsa models, I was introduced to cardboard airplanes and have built with cardboard ever since.
