The tailplane was mounted on top of the fuselage and together with the elevators was elliptical in plan. The elevators carried trim tabs. In its initial configuration the fin was longer in chord than high, carrying a nearly semicircular rudder that extended down through a cut out in the elevators to the base of the fuselage. 215: 195:
repositioning of the oil radiator. It was a little (5 km/h) faster than the 490 and was over 3% quicker in the climb. Despite its excellent performance in terms of the original specification and its ability to perform aerobatics like a fighter, the production order went to Les Mureaux on the basis of their machine's superior climb rate.

The vertical, faired main oleo legs of the split axle undercarriage were mounted on the forward lift struts, with two more articulated struts on each side to the bases of the lift struts. The single mainwheel on each side was initially uncovered but later acquired spats. There was a tail skid at the

The parasol wing of the 490 was of straight, untapered plan apart from elliptical tips. For its time the all-metal wing was thin, with a thickness/chord ratio of 8.5%, and was built up around two spars. The ailerons were split into two pairs. Streamlined lift struts ran from the lower fuselage
