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 havin similar handling characteristics to other 4-stroke model engines:-
After the considerable success of the RCV58-CD, the latest addition to our RCV CD range is the RCV91-CD. This 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 91 4-stroke engines (or .60 2-stroke engines), this is the ideal choice for scale, aerobatic, fun and general 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. 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 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 RCV91-CD engine is a perfect option.
