The official website of Sonex Aircraft LLC:

Sonexplans, Waiexplans and Xenosplans are Yahoo groups exclusively for plans owners (ie builders and aircraft owners) of the respective aircraft. The sites are moderated by Sonex and are used as the means of keeping owners up to date with issues and developments associated with their aircraft, as well as a valuable source of information and ideas shared between owners and builders.




Sonextalk is for current and future Sonex builders. It is not moderated by Sonex. You must be an approved member to post to the site:

You can keep in touch with Aerovee engine developments through the Aerovee Yahoo group moderated by Sonex:

You can join a group open to all interested in Jabiru engines. Not moderated by Sonex or Jabiru. Posting by approved members only:

You must join these groups and decide how to receive postings. You have a choice of having every posting forwarded to your email address as they come through (it gets tedious!). A better way is to get the site to prepare a single email of all postings in the last 24hrs and to send it to you daily. You can scan and read what you want. You can select these options on the site. Otherwise, you can go to the sites any time you like and search for previous postings.
