In the early 1930’s, Henry Parohl, of NY, was setting records with his model powerboats and homemade miniature engines—two and four-cycle singles and twins. Then he began designing more complex three and five-cylinder radial aircraft engines. Although the radials are quite a change from his early boat engines, Mr. Parohl’s building technique and style have been retained throughout his engine building career.
This 3-cylinder radial is a one-of-a-kind custom design that runs on regular gasoline and has a spark ignition. Built around 1960, this engine is 9”-long, 12”-wide, and 9”-high.
