4-Stroke Model Aero Engine

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:-

RCV58-CD - 0.58 cu in / 9.5 cc


CD Series Features

bullet Ultra Compact Design - over 1" shorter than conventional 52 4-stroke engines
bullet Low Noise - Unique Real Engine Sound
bullet Uses Conventional Propellers Sizes
bullet Can be mounted inverted
bullet Low Maintenance
bullet Easy to Tune
bullet 2-Year Guarantee
bullet Suitable for modellers of all skill levels

The RCV58-CD has been designed to meet the demand from aero modellers who want a quality engine, that is easy to use and is competitively priced.  Comparable in power to conventional 52 4-stroke engines (or .40 2-stroke engines), this is the ideal choice for scale, aerobatic, fun and general flying.  These engines are now starting to be used for training.  Check out our for examples of what the RCV58-CD is capable of flying. 

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.
So if you are looking for a reliable, easy to use 4-stroke engine, that is the same height as a 2-stroke engine, our die cast RCV58-CD engine is a perfect option.
