I thought Columban did not sell plans for construction in the U.S. Do these plans precede that decision or were they sold in another English speaking country?

Mmmm, I miss the smell of ammonia when I see prints like that.
Gawd I don't miss the smell of ammonia in the engineering office or the room where the print machine was. I do miss the artistry of pen or pencil on paper or mylar but I wouldn't take it back if I had to trade it for what I have now. CAD doesn't make drawings like we used to make but they are WAY more accurate and easier.

Those plans from Zenair are questionable? I think they had problems, (Structural failure) ,that is the reason Colomban quit selling plans to North America.
Zenair made changes to the original design.

If you build it to the plans on the large sheets, there won't be any issues as they are exactly the same as a Colomban set. The issue was with the changes in the Cricket kits and the 20 or so A4 sheets done by Zenair. Stick to the large paper plans and the construction manuals and you should be fine!
