My nephew Luke is visiting from Phoenix. His friend Jason is also here and knows I'm into kiting. It turns out Jason has a website with paper airplane files you can download.
There is a free sampler so you can get an idea of what it is all about.
He makes about enough money to cover the cost of the website. Turns out that France is the country which buys the most of his models. The models are also popular with science teachers. Give it a look see.http://www.jplanes.com/
