The Breguet-Michelin 4 (BM4) was developed from a 1915 design, but production delays and problems in testing delayed its debut until April 1916. Being somewhat obsolete by 1916, they were not well-liked by their crews. But that did not prevent 200 of them from being built and deployed and used extensively until they could eventually be replaced by Breguet 14's or late-model Voisins. Remarkably, it was not until May 1918 that the last unit gave up their BM4's.
This model comes in 1:144 and 1:285/6mm/1:288 scales. Smaller-scale planes come with propeller disks rather than blades.
