Arup S-2

The aircraft was demonstrated across the country at events like the Indianapolis 500 and the 1933 National Air Races.

Engineer Charles H. Zimmerman viewed the S-2 trials in Washington and later applied the principles to the Vought XF5U program.

A Szekely radial engine removed from an American Eagle Eaglet was installed on the S-2, but did not perform well.
