The RCV91-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 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.
