Aircraft fan blades in msfs

Hi guys,

Have always wondered if i could make the fan blades windmill into the wind when the engines are shut down like in this video?

Any ideas how i could do this CFG tweaking etc? Also i've noticed when you do shut down the engines on any turbo fan aircraft in msfs the fan blades spool down too quickly unlike in real life they would still be rotating several minutes later after the engines have been shut down? Any ideas also how i could make the fan blades spool down in a slower sequence when shutting down the engines?

 

 

 

(i've noticed that the captain sim 757's fan blades do windmill ever so slowly though. If you have the CS757, when the engines are fully shut down have a quick look at this effect its quite cool!)

 

Thanks,
