The Kinner R-5 is an American five cylinder radial engine for light general and sport aircraft of the 1930s. The R-5 was a development of the earlier Kinner B-5, with slightly greater power and dimensions. The main change was the increase in cylinder bore from 117 mm (4.625 in) to 127 mm (5 in) and an increase in cylinder stroke from 133.3 mm (5.25 in) to 139.7 mm (5.5 in). This led to a corresponding increase in displacement from 7.2 liters (441 cu in) to 8.8 liters (540 cu in).
The head of the R-5 Series 2 has approximately three times as much cooling fin area as previously used cylinder heads, having longer fins spaced closer together. A greater angle between inlet and exhaust valves results in a stronger head and provides additional metal between valve seats. Cylinder heads have rear exhaust ports and lugs are provided for support of cowling rings.
Enlarged intake passages and valves increase the efficiency and result in higher brake mean effective pressure.
Bearings have been increased in size. The crankshaft has been greatly strengthened by increased sections. The main and master rod bearings are of the copper lead steel-backed type. Master-rod sections have been enlarged and design altered to give a very much stronger rod with little increase in weight. Improved front cover provides additional strength and durability. All oil passages are contained in the engine.
Rocker arms have a roller supported on needle bearings on valve end which reduces side thrust on valve and increases life of valve guides. High pressure grease lubrication is provided for the main roller bearing of the rocker arm and the rocker arm end of pushrods. Pushrod rocker arm adjusting screws are designed so that with their removal the pushrod can be withdrawn through the opening of the rocker arm for inspection.
The Kinner R-5 Series 2 employs a separate camshaft for each of the five cylinders. Each camshaft includes a simple spur gear driven by pinion gear on rear end of crankshaft at one-half engine speed.
Spur type magneto drive gears are driven by the cam gears. Oil pressure and scavenger pumps are driven by shafts keyed into slots in the ends numbers three and four camshafts, respectively.
Provision for Eclipse compressed air started and Eclipse Y150 direct electric starter, also generator and fuel pump drives are provided. Each accessory has its own mounting pad. Provision is made in oil sump for Cuno oil filter.
This engne may be fitted with battery ignition and two machine gun synchronising drives were available.
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 World War II trainer aircraft, its military designation R-540.

The Kinner C-5 was an American five cylinder radial engine for small general and sport aircraft of the 1930s. The C-5 was a development of the earlier R-5 with greater power and dimensions. The main change was the increase in cylinder bore from 128 mm (5.0 in) to 143 mm (5.625 in) and an increase in cylinder stroke from 140 mm (5.5 in) to 145 mm (5.75 in).

The Kinner B-5 was a popular five cylinder American radial engine for light general and sport aircraft of the 1930s.
The B-5 was a development of the earlier K-5 circa 1928, with slightly greater power and dimensions. The main change was the increase in cylinder bore from 108 mm (4.25 in) to 117 mm (4.625 in) and a corresponding increase in displacement from 372 cu in (6.1 liters ) to 441 cu in (7.2 liters ).
One difference the B-5 had from radial engines of other manufacturers was that each individual cylinder had its own camshaft, a system also used by the contemporary Soviet-built Shvetsov M-11 five cylinder radial, while most other radial engine designs used a “cam ring” for the same purpose, connected to every cylinder’s valves.
The B-5 was a rough running but reliable engine and the B-5 and its derivatives were produced in the thousands, powering many World War II trainer aircraft, its military designation was R-440. The B-5 was followed by the R-5 and R-55.

The Kinner K-5 crankcase is manufactures from heat treated aluminium alloy castings, consisting of three pieces, the main cylinder sections and front and rear covers. The removal of the covers makes immediately accessable the crankshaft, bearings, master and link rods, cam gears, followers and magneto drice gears.
The crankshaft is of a special heat treated chrome nickel steel drop-forging, machined all over, counter balanced and supported on two main bearings of special bronze backed babbit. The thrust bearing is a Hoffman ball bearing. Special force feed lubrication is to the link pins.
A special air heater is provided permitting air to be drawn from top or side of the fuselage. A special annualar intake passage is cast in the main crankcase distributes the combustable mixture.
Valve rocker arms are enclosed in a streamlined cover. Inlet and exhaust valves are both necked type of special heat resisting steel alloy. There are individual camshafts for each cylinder.
Accessories available at extra cost were Heywood self starter, Eclipse hand turning gear, and propeller hub.
The Kinner K-5 was a popular engine for light general and sport aircraft developed by Winfield B. ‘Bert’ Kinner. With the boom in civilian aviation after Charles Lindberg’s transatlantic flight the K-5 sold well. The K-5 was a rough running but reliable engine and the K-5 and its derivatives were produced in the thousands, powering many World War II trainer aircraft. The K-5 was followed by the B-5, R-5 and R-55. Circa 1928, the K-5 produced 100 hp at 1810 rpm, with 73 Octane fuel.

During 1937 company still offered six types of engine and was working on twin-engined Invader, but in 1938 was in receiver’s hands, though continuing operations under control of a trustee.
Envoy was scaled-up Playboy seating four. Three Envoys acquired by U.S. Navy as XRK-1 were not experimental, but staff transports.
Kinner Airplane and Motor Corp. introduced an airplane of its own design in 1932. The side-by-side two-seat Sportster series of low wing taildraggers was powered by 100-hp Kinner five-cylinder radial engines. Some have been repowered with the 125-hp Kinner. The aircraft employed a mixed construction with the conventional fabric-covered wooden wings and fabric-covered steel-tube fuselage combination.
The Sportwing was a refined version with eight built circa 1935.
