C. M. Manly constructed a water-cooled five-cylinder radial engine in 1901, a conversion of one of Stephen Balzer's rotary engines, for Langley's Aerodrome aircraft. Manly's engine produced 52 hp (39 kW) at 950 rpm. Most radial engines are air-cooled, but one of the most successful of the early radial engines (and the earliest "stationary" design produced for World War I combat aircraft) was the Salmson 9Z series of nine-cylinder water-cooled radial engines that were produced in large numbers. Georges Canton and Pierre Unné patented the original engine design in 1909, offering it to the Salmson company; the engine was often known as the Canton-Unné.

 The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders"radiate" outward from a central crankcase like the spokes of a wheel. The pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings around the edge of the master rod. Extra "rows" of radial cylinders can be added in order to increase the capacity of the engine without adding to its diameter.

The kit

A 1:6 engine comes in quite a large box, as I soon realised. Actually, it's a very high quality tin, with a lid that lifts right off to display an instruction manual sitting between two pieces of protective foam. The lid itself shows an illustration of the completed engine, while the side has the kit-specific details. For an idea of scale, I've sat my Swann Morton retractable scalpel on the kit. There's a reasonable amount of weight in this kit too...approximately between 1.5 and 2kg. No surprise as this kit is 99% metal. The side panel of the tin gives a few more details.

All of the parts in this kit are recessed within sturdy foam trays that also have the part numbers engraved into the foam, adjacent to each part. This makes it ridiculously easy to find exactly what you need in each stage. There are FOUR trays of components in this kit. While there are are a number of electronics parts, with the exception of these and the plastic cylinder head rockers, everything is in cast or machined aluminium etc. 

You'll notice the white plastic box in that tray. That's choc-full of screws, turned parts, springs, bearings etc. Each little section is padded with some foam. Again, there's no lube in this box. It must be something they had to leave out for some reason. Quite add as the kit contains another contentious item....a lithium battery.

The lack of lube in the kit meant that I needed to buy some. I opted for this stuff, and used cotton buds to apply to the various connections. The manual us very clear about where lube is to be added, and this generally centres around the pistons and crankcase...not inside the piston heads.
