The Renard R.31 was a monoplane with a high wing. There was a composite skin over the metal skeleton.
The Renard R.31 was hard to handle and thus unpopular with the pilots.
On October 16, 1932, the Renard R.31 prototype took off for the first time. In March 1934, 28 were ordered. Six more were ordered in August 1935.
There were 34 Renard R.31s in operational units.
The final mission for the Belgium Air Force was on May 27, 1940, and the Renard R.31s took part.
