Can anyone take a stab as to what the device below the swashplate might be? Clearly an arm leading to some sort of horizontal stabiliser but a most uncommon accoutrement for this (or indeed any) type!
Found this in the Sikorsky Archive. If it is the same device it would be something called Ericsson stabilize.
Not very many details, but seems to be sound. Frank Ericsson was an interesting character. First US military helicopter pilot, who earned his license directly was Sikorsky, and later was in charge of the first US military helicopter school.
