I built a few T Squares when I was a teenager. Boy that kit was inexpensive. $3 - $4 if I remember right, and very simple to build. A little Ambroid, 1/2 sheet of silkspan, 3 - 4 coats of clear dope and you were in the air. Powered them with whatever I had handy. I never flew any combat but the plane was a blast to fly. I even had one that I cobbled a tricycle landing gear so I could launch from a stooge.. I think Sterling was the mfgr. Is the T square an exstinct species or do they still ply (no pun intended) the skies?
