A propeller system includes a rotatable housing having at least one propeller blade mounted thereon and an electric pitch control motor within the rotatable housing. A pitch control member is coupled to the propeller blade and extends through a wall of the rotatable housing. The pitch control motor is configured to move the pitch control member and to thereby vary the pitch of the propeller blade.
