Actually, ACad should be perfectly adequate for most of the Airbike.
It's a pretty basic set of plans for a basic plane. It's all 2D on
paper so there is no need for 3D files. I have better CAD and can do
the "nasty" stuff. If you or anyone else is seriously interested in
doing the Airbike in CAD I'd be willing to kind of coordinate the
project, even though I don't have time to make much of a contribution
myself due to other projects time demands. I'll never build one but I
know that there are many others that probably would if they could get
a set of plans..................

Contact me off list if you are interested.
