The Robin DR400 was released in 1972, as a development of the DR300 series. Compared to the latter, the two major differences of the DR400 are a wider cabin at shoulder level and a forward-sliding canopy, a new concept introduced with the Robin HR-1 in 1969[3][page needed], made to replace the doors present on earlier series. The wings have a 'cranked-wing' configuration, allowing for stable cruising and safer stalls. The dashboard is also clearer and more elevated than on previous models, allowing easier instrument readings.
