Airchair Technical Drawings

Last Update: January 9, 2022

Here are the technical drawings which describe the airchairs I have designed, built, and flown.

They are released into the public domain and are free to anyone for any purpose. 

Each aircraft is described by a set of about 69 to 96 drawings. The drawings are intended to describe the aircraft as it was flown.

1. Technical Drawings as Bitmaps, Viewable on the Web and Down loadable

For web viewing and downloading of drawings (in raster format, .gif bitmaps) go to my Online Photo Albums at:

These albums currently include the drawings for Goat4, Goat1, and Pig1.
Individual drawings can be downloaded directly from the online Gallery.
See below for downloadable files which contain all the drawings for a particular aircraft.

2. Technical Drawings in Download Files

These down loadable files are in vector CAD (Computer Assisted Design) formats, .dxf, .dwf, or .tcw (Turbocad, recent versions), except when in .gif which is raster (bitmap).

 Drawings in AutoCAD format (.dxf) offer a much better view of small detail than the bitmaps (.gif) and should be preferred for any critical examination of the drawings. Also, a modern CAD program can use the .dxf files as a starting point (template) for making new or modified drawings, or as a source of components (the individual nuts and bolts can be taken out of the  original drawings and used elsewhere).

 I may make changes to the drawings on occasion. Check the date on the viewable version of the drawing above to know if a drawing you have printed out is up to date. A later date will indicate that the drawing has been changed. Also a higher numbered zip file indicates a change.

Advisories:  I use only steel quicklinks (maillons). Aluminum quicklinks have recently become available, anodized in colored finishes. I have not used aluminum quicklinks because I suspect they would not be strong enough for my purposes.
