Amongst the many uses for the Scarab, the engine was fitted to the
Cessna Airmaster and the famousFairchild 24 (UC61 or Argus).Thousands of these reliable engines soldier on today, many still powering the aircraft to which they were originally mounted.
They are also in demand as realistically sized (albeit far more powerful) engines to be fitted to replica or restored WW1 biplanes
Junior
A scaled-down version of the engine was produced as the Warner Scarab Junior.
