Abstract
Disclosed is a simultaneous twin pitch adjustment system that includes a flexible shafting cord operatively connected to first and second couplers. The couplers are supported by posts and are operatively connected to pitch communicators. A handle is supported by each post and is configured such that manipulation of the handle translates to adjustment of the pitch of an associated rotor blade assembly. When the simultaneous twin pitch adjustment system is engaged, manipulation of one handle further translates, via the flexible shafting cord, to adjustment of the pitch of another rotor blade assembly in an amount essentially equal to the amount the associated rotor blade assembly is adjusted.
