Hybrid XT Vane Head Damping

The Hybrid XT Vane has damping in the head to reduce overshoot and oscillation behind the turbine rotor. One result of
this is that the frequency response has been lowered slightly. This may, in some limited circumstances, require a slight
adjustment to the turbine controller settings when retrofitting a Hybrid XT in place of an IceFree 2, IceFree 3, or an
original Hybrid. Please contact Renewable NRG Systems for further information.
