yes, you have no winch normaly for cargo
in the civil world you have 12, 20, 30, 45m Long Line (standart Logging OPS) etc...
a Winch would be too heavy...
There are different release variants. always a Mechanical Hook Release and a Panel where you can choose which hook or Function is active on the ControlStick. Lower Hook, like the Long Line for Wood, BambiBucket Water Relase etc. or simply the upper Hock on the Helicopter.
