The RCV - rotary cylinder valve four stroke engine represents a major advance in model engine design. Although its moving components (piston, crank, cylinder and rotary valve) are totally conventional, they are arranged in a radically novel configuration to provide the aero modeller with several key benefits, whilst having similar handling characteristics to other 4-stroke model engines:-
CD Series Feature
Ultra Compact Design - over 1" shorter than conventional 52 4-stroke engines
Low Noise - Unique Real Engine Sound
Uses Conventional Propellers Sizes
Can be mounted inverted
Easy to Tune
Low Cost Spares
Suitable for modellers of all skill levels
The RCV 4-cycle engine has only one more moving component than a 2-cycle engine -the rotating cylinder itself. The cylinder is suspended
between two bearings which allow it to rotate freely around the piston; the piston, and crank are entirely conventional. A gear formed
around the base of the cylinder meshes with a gear on the crank. As the piston reciprocates and the crank turns, the cylinder rotates
around the piston.
At the top end of the rotating cylinder there is a single port leading to the combustion chamber. This is surrounded by a fixed timing
ring with three radially arranged ports; inlet, ignition and exhaust. This simple valve arrangement serves the combustion chamber
as the engine cycles through the conventional 4-cycles: induction, compression, power and exhaust. Ignition is achieved through a
standard 4-cycle glow plug exposed once only during each complete cycle.
The rotating cylinder is effectively combined with the rotary valve in a single component hence - RCV - Rotating Cylinder Valve.
The engine still uses RCV's unique rotary valve system - which has only one extra moving component to a 2-stroke and so is easy to maintain. This ultra-compact engine is the same height as a conventional .52 4-stroke engines (or .60 2-strokes) which makes cowling much easier than other 4-strokes

The engine still uses RCV's unique rotary valve system - which has only one extra moving component to a 2-stroke and so is easy to maintain. This ultra-compact engine is even shorter than conventional .90 4-stroke engines, so once again cowling will be much easier than other 4-strokes.
So if you are looking for a reliable, easy to use 4-stroke engine, that is easy to cowl and sounds like the 'real thing' then the
RCV130-CD engine is a perfect option to power your 90 - 120 size model.
