Just a small correction. The USA Experimental category of a Diana is "Racing/Exhibition" not "Homebuilt." There is a difference.

To be considered "Homebuilt" at least fifty percent of the construction must be completed by an amateur builder. Normally this means the aircraft is delivered as a "kit" and assembled and flown by the builder. However, many have been built directly from a set of plans. (Woodstock, Duster, Tern, BG series, etc.)

The most popular US "Homebuilt" series of sailplanes were designed by Dick Schreder.

If the glider is without EASA Certification it is general rule. But I
think in USA it should be different. What I know all Diana's are there
flying in Experimental category. It means as "home build" gliders and
the responsibility is on the pilot.
