what i was saying was that the dual hydraulics eliminates the problem of hydraulic failures as a result of a belt or similar but it does not eliminate the problem of the weak actuator and the week actuator is so because if it were stronger it would shatter the starflex.
i have flown b2, b3,(not fitted as standard i know ) and ec130 all with dual hyd and was warned about SCT on them all.
its what i have been told, im not saying its true.
and also if the starflex is so good, why does the ec120 have such a different head although they call it a starflex from memory it has dampers and weights etc.
