Jack Stafford Ercoupe (AirCoupe?). Finally got so mad, I tossed it in the corner and never touched it again.

Sterling Stearman was bad, too. This one was started around 1990. Bought from Tower. Plans were so old, there wasn't even a zip code on the address. Every fuse former was so brittle, it would snap in half if you tried to put a pin in it. Firewall was 2 3/8" pieces of square plywood that you had to glue together and cut out to the round shape. I was helping a friend with this one. He finally got frustrated and threw the whole thing in the trash.
