I sell full size .pdf files of all my airplane plans for $5.00 per airplane. The full size files can be printed to full size paper plans at a copy shop or blue-print shop that has a large format printer. The files are sent via email, so there is no shipping and no stupid customs interference. PayPal US$5.00 to firstname.lastname@example.org
will get you the file. The plans show all the parts full size, so they are not difficult to use for scratch building.
