02/28/2009. James Vidervol and Arpad "Art" Szaraz, of Cleveland, Ohio, designed the Vidervol-Szaraz VS-1 two-seat high-wing monoplane.
First flown on October 4, 1961 it acted as a prototype for the SDI-A Daphne which Szaraz developed from the VS-1.
In 1961 Nick Stanich bought from Szaraz the plans for the Daphne and started construction in the garage of his Berea, Ohio home with
the help of his wife Joye, his son Nick Jr., and his neighbor Dan Bookwalter. Nick redesigned the SDI-A to have full-span ailerons.
Fitted with an 85 hp Continental C85-8 four-cylinder horizontally opposed air-cooled engine, the aircraft flew for the first time on
February 28, 1965, registered as N962Z.
