1. A wind turbine including a tower supporting a main boom carrying a rotor of the axial flow type and at least one generator,
the rotor having a main rotation axis, the rotor including a hub carrying a number of blades being supported by blade lines,
each blade being attached rotatably to the hub about a pitch axis, which is parallel to a longitudinal direction of the each blade and at an angle to the main rotation axis of the rotor, and
each blade having a total blade length from the hub to a tip of the blade, wherein
a pitch angle of each blade about its pitch axis is controllable by coordinated movement of a set of at least a first displaceable pitch control cable and a second displaceable pitch control cable acting on said blade, and in that each pitch control cable has a blade end being attached to the respective blade and has a boom end being attached to a pitch control member arranged rotatably on the main boom and being adapted to displace the pitch control cable.
