Hardly any engine fascinates more than a radial engine. The incomparable sound, the circularly arranged cylinders and valve trains, as well as the massive crankcase, know how to inspire every model pilot. Especially for replicas of originals with radial engines, Saito offers a selection of engines that not only stand out visually, but are also distinguished by their performance and, above all, their reliability.The FG-90R3 is the increased displacement version of the well-known FG-84R3. The dimensions, however, have remained identical. The special Walbro carburettor supplies the engine reliably in all flight conditions. The heat sinks reduce the engine temperature through better cooling even under demanding conditions.
