If the design is not protected against copying by IP laws,
the contract would have to specify not only that the
original purchaser can't build two, but that he can't sell
the plans. Does it include stuff like that? Anyone have
any actual language in e-format they can post?

OK. I have a set of drawings for the Dyke Delta JD2. I did
not buy these plans, they were handed to me after the
purchaser died. Since I have no contract with the designer,
are you saying that I am free to copy and sell as many
prints as I feel like?

It's not a contractural issue. Can you say COPYRIGHT? I knew
you could. Copyright forbids you from copying the plans without
permission of the owner. Copyright also prevents you from making
derivative works (that is, building an airplane from those plans) without
such permission as well. Lots of case law on this with regard to architectural
plans.
