A partly cruciform flexbeam (1) of a bearingless main rotor system of a helicopter with a hub drive and an airfoil blade. The partly cruciform flexbeam (1) comprises a flexbeam head (2) with a flat bearing laminate at one end, a root end (3) opposed to said flexbeam head (2) and a flexbeam body (6) between said flexbeam head (2) and said root end (3), said flexbeam body (6) being torsion soft with a substantially cruciform cross section. The invention is as well related to a method of manufacturing such a partly cruciform flexbeam (1).
