X-Plane 9.70 – Caudron C. 630 Simoun. The Caudron C630 Simoun was a four-seat single-engine low-wing monoplane powered by a 220hp Renault Bengali-Six air-cooled engine that had made its first flight in October 1934. The Societe “Air Bleu” was the biggest civil user of the aircraft and opened a service between Paris – Tours – Poitiers- Angouleme – Bordeaux with the Caudron Simoun F-ANRI. Credit goes to Joe Rimensberger who provided the picture to build the customized panel and to Pyperpote who provided high resolution pictures of gauges. Lastly, credit goes to XPFR for their pilot collection. By Philippe Gastebois.
