The Sig Kougar still has printed parts you have to cut out. Great building and flying plane though.

Back in the day, the kits that were the worst were the ones that had poor die cutting of really hard balsa. The ACE 4-60 bipe was the worst one I ever built. It had multi spar construction and all those little notches for the ribs just crumbled when I tried to get the ribs out of the sheets. What a mess. The wing wasn't all that stout and looked horrible after it was built and covered. This is as opposed to your typical D tube construction with partial sheeting and rib cap strips. However; that old 4-60 bipe flew fanstastic.
