I looked and looked too. Best ones I found. I then found the Americas_3 plans and they are complete and a similar looking boat. As most of the cup style boats, look similar. They all have very nice lines and a good subject to model.
With the Americas_3, I had this bright idea of printing it out at 200% for a bigger model. Got it all setup in Adobe, hit print. Heard the printer cranking out page after page after page after page and thought HUH!!! I thought the plans were for a 650mm boat. Then I see they are for a 1.2m boat. So now I have it printed, not sure I could fit it in my little car if I did build it. Would be a site to see though. A RC sail boat with a 8 plus foot mast. Would be a nice project. Would not be a weekend build for sure.
