construction and development
The engine is a further development of the Kinner B-5 with a little more power and slightly larger dimensions. The biggest changes were an expansion of the bore from 117 mm to 127 mm and an increase in the stroke from 133.3 mm to 139.7 mm. This resulted in an increase in displacement from 7.2 liters to 8.8 liters. The R-5 is a somewhat restless but reliable engine, thousands of which were installed in training aircraft during World War II . Its military designation was R-540.
