This custom single-cylinder .60 model aero engine was built by Charles “Chuck” Harty, of Colorado, in the 1990s. The engine measures about 5-1/5”-tall, 5”-wide, 6”-long, and weighs 2.5 pounds on the stand. It was machined from aluminum and steel, sports roller rockers, and burns gasoline on spark ignition.
