A proprotor system (100; 200; 300; 400) for tiltrotor aircraft (10) having a helicopter mode and an airplane mode. The proprotor system includes a hub (102; 202; 302; 404) and a plurality of proprotor blades (112; 212; 312; 402) coupled to the hub (102; 202; 302; 404) such that each proprotor blade (112; 212; 312; 402) is operable to independently flap relative to the hub and independently change pitch. In the airplane mode, the proprotor blades have a first in-plane frequency greater than 2.0/rev.
