Homebuilt.org is an online source of information about sport aviation and homebuilt aircraft.
Here you can find an index containing company’s sites, information on the different companies, a list of builders of homebuilts, and design software, among others. This is a volunteer project and there is no charge for links listing here since this is a non profit site. So, the website is sorted into different categories such as kits and plans, vendors, homebuilders, and technical information, among others. Each one displays a list with links and information about the different companies from those categories. In addition to this, the site also offers a free classifieds section where users can post their ads for free. In case you own a homebuilt website or you know of one that is not listed here, you can send it to the webmaster, who welcomes any contribution. All the contact information is posted here.
