The MSrE M-21 Harag was an aerobatics aircraft built in Hungary in 1936 sometimes known as the Szegedy M-21 after one of its designers József Szegedy. It was a conventional biplane design with single-bay staggered wings of equal span braced by N-struts. The pilot sat in an open cockpit and the tailwheel undercarriage featured divided main units. Only a single example was built.
