I have forgotten how to set engine shut down times in FS2002 & FS9 . I have a beautiful T-6 that windmills at length after engine shut down while the sound stops very early . As I recall it was somewhere in Aircraft config .

thanks ,

Jamie

Having just seen a handful yesterday I can tell you that they do tend to stay on long after the fuel is cut... Wink

Those have the P&W PT-6 in which the prop is not connected to the gas generator. They will windmill as long as there is a slight breeze blowing unless they are mechanically restrained.

cheers,
Joe

Don't argue with idiots, they drag you down to their level and beat you with experience.

Hi All ,

I have set them in the past , but may have been FS98 . Took some time fiddling with the config file , but had them stopping beautifully . This was for piston engines planes only .

Feather the prop... rotates the prop parallel to the airflow, and will stop the prop from windmilling. This can be done on most advanced pistons and turboprops. If you feather the prop after shutdown, it will stop fairly quickly.

No no. This is the original T-6 Texan.

Most people change the prop MOI value in the CFG file.

Hope this helps,

Hi Tom ,

I knew I had set that in the past and that was where . I did try it a little before posting , but had forgotten that it took such dramatic changes in the MOI . My Waco Classic prop stopped instantly at shut down so I changed the MOI from 1.7 to 40 and came close to being correct . Will take a lot of fiddling to get it really good . I set the T-6 from 14.1 to 3 and was much much better . Have not attempted to coordinate sound files .

Thanks so much Tom ,

Jamie

I have FS2002 and 2004 and have only changed items in FS2002 so far . If you would like to see the difference these are some changes I made for three planes that make them more realistic :
T-6
Normalized start torque -- 1
Prop MOI -- 2

Waco Classic -- MOI - 30

Spartan Executive -- MOI - 3

Fine. What's your suggestion?
