This may not be fact, but from memory:

* The events had to be completed by one plane.

* Plane had to have external tank (perhaps specific size).

* I remember suggested modifications on the Junior Nobler plans for AYSC (I think it was Air Youth State Championships).

* I THINK Mackey's "Hummingbird" was designed for AYSC use.

* I believe it died out due to lack of participation.
