A propeller assembly (20) has a plurality of propeller blades (26), and a pitch change mechanism including at least one motor (48). A drive input (32) drives the plurality of propeller blades to rotate about a central drive axis (Y). The pitch change mechanism is operable upon driving of the motor to move the propeller blades about the drive axis relative to the drive input. The drive input includes a drive input gear transmission (62,68,56) to change a pitch angle of the blades when the blades are moved relative to the drive input by the pitch change mechanism. Further, a method of operating a propeller assembly to change a pitch angle is disclosed and claimed.
