H,

The rest of the department store ARFs were heavier and did not fly as well (if you could call it that) as the PT-19.

COX did put out a decent flier or two in the late 1970's - Me109 (and a Chipmunk ?). These had much larger, lighter wings - thin sheet foam. The wings were molded open, looked like a VERY wide "W". They folded on the leading edge. The trailing edges glued together, and the root airfoil formed on a fillet molded into the fuselage, and a glue-in tip set the airfoil. Body had a stub spar a few inches long to support the wings.

Symmetrical airfoil. Capable of stunt pattern maneuvers, in good conditions.

Much later, they tried a solid foam wing 'sorta F-8', sorta ARF. Could fly a few maneuvers in good conditions. Didn't seem to catch on.

To your question: No idea if anyone tried to piece together any of these series from spare or salvaged parts. Other than nostalgia, I wonder why anyone would be interested to try that.
