My mistake, i misunderstood a previous message.  I am more than happy to share.   ;D

Google 'Wildfire Pilot' go to the downloads section and download the fire retardant effect.  Sorry I dont have enough posts to add a direct link.   :'(

(1) Copy the "fx_fire_retardant.fx" file to your "Effects" FSX sub directory; C:/Program Files/Microsoft Games/Microsoft Flight Simulator X/Effects

(2) Copy/replace the following lines into the Captain Sim C-130H "aircraft.cfg" file. C:/Program Files/Microsoft Games/Microsoft Flight Simulator X/SimObjects/Airplanes/CS_EX2_C130 etc...

[smokesystem]
smoke.0=12.00, 8.00, -15.00, fx_fire_retardant.fx
smoke.1=12.00, -8.00, -15.00, fx_fire_retardant.fx

(Please realize this will replace the default engine smoke effect for ALL CS_EX2_C130 (C-130H) liveries; to regain simply copy the default smoke entry from any other Captain Sim C-130X-perience aircraft folder/aircraft.cfg)

(3) To see it in action; press/hold the "I" key (smoke command)

Im still working on the problem when the aircraft is set to full throttle the smoke system is triggered and a drop of retardant is let go........kind of makes a mess on the runway.
