If anyone is interested in slingloads for helis and has aicarriers installed you can add the objects used in the missions in fsx by adding the object which are located in simobjects/misc and usually end in sm to the ai carriers cfg examples below.
[formation.xx]
title=Humvee_sm
unit.0=Humvee_sm, 0, 15
[formation.xx]
title=TopSecret_Crate_sm
unit.0=Topsecret_Crate_sm, 0, 15
[formation.xx]
title=Generator_sm
unit.0=Generator_sm, 0, 15
You can only use one item at a time and to use the slingload if its to heavy for the hoist save your flight go to the FLT file located in my documents/flight simulator x files and change this line in sling.1.0 CableLength=0 change 0 to 65 and when you restart your saved flight you should have a slingload cable attached. If you use both the slingload cable and the hoist together, both items will be released together for default eh101.
