- Kinner R-5
The Kinner R-5 was a popular engine for light general and sport aircraft. The R-5 was a development of the earlier B-5 with slightly greater power and dimensions. The main change was the increase in cylinder bore from 117mm (4.625in) to 127mm (5in) and an increase in cylinder stroke from 133.3mm (5.25in) to 139.7mm (5.5in). This led to a corresponding increase in displacement from 7.2 liters (441 cu in) to 8.8 liters (540 cu in). The R-5 was a rough running but reliable engine and the R-5 and its derivatives were produced in the 1,000s, powering many
