1. A method of installing rotor blades of a wind turbine on a rotor hub of the wind turbine, wherein the wind turbine has a tower with a tower longitudinal axis, wherein the rotor hub has first, second, and third rotor blade connections, the method comprising:
rotating the rotor hub until the first rotor blade connection is at an angle of 90° or 270° with respect to the tower longitudinal axis,
lifting the first rotor blade substantially horizontally and fixing the first rotor blade to the first rotor blade connection,
rotating the rotor hub so that the second rotor blade connection is at an angle of 90° or 270° with respect to the tower longitudinal axis,
lifting the second rotor blade substantially horizontally and fixing the second rotor blade to the second rotor blade connection,
rotating the rotor hub until the third rotor blade connection is at an angle of 60° or 300° with respect to the tower longitudinal axis,
lifting the third rotor blade at an angle of 30° with respect to a horizontal, and
fixing the third rotor blade to the third rotor blade connection.
