MD530F cold and dark saved flights

Hi

I have figured out how to add a sling line to the underneath of the aircraft which is done by saving the flight and editing the saved flight file and adding sling loads  so I can do some slingloads.

In the mams when I select engines running my sling line appears and works

But when  change to cold and dark the sling line is gone.

Is there a way to change how saved flights behave.

I would like to start my slingload flight cold and dark 

Cheers

Rhys
