In September 1930, Art Chester bought a Davis D-1-85 parasol, and flew it to victory in the 1930 National Air Races.[2] A late model D-1W "The Whistler II" was built in 1933 for Davis with a canopy. It was raced in the 1934 Miami air race by Art Davis winning the category at 133.478 mph. It was later owned by movie star Richard Arlen, and restored to become a Grand Champion antique.[3]
