An email list for discussion of homebuilt small blimps has been started:

Littleblimps[LBlimps]:  Discussion group for enthusiasts, designers, builders and fliers of small blimps.   The purpose is to promote the development of practical, homebuilt, inexpensive blimps.  Comments and reports on construction techniques, materials, designs, etc., as well as flying, landing, hangaring, etc. are welcome.   While the main purpose is to enhance the enjoyment of person-carrying blimps, descriptions of experience with model airships can be valuable.
Advertisements that are directly related to blimps, and are likely to benefit a subscriber or two, are acceptable.
The listowner is Reed Gleason, reedg@teleport.com, telephone 503-283-1366.  Please direct complaints to me, not to the list.
