Compact Design - 60 size 4C engine with a super low profile making it an ideal power plant for many scale projects
AT 6 Texan
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:-
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. Its ultra low profile, means the height of this engine is approximately 18mm less (compared to OS & Magnum) & the highest point is 14 mm further back which makes cowling much easier than with other engines.

How it Works
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.
