I was looking at a few clips of the C130 for CS and real clips on youtube and I noticed that the CS130 engines start up wayyy too quickly...has anyone found a fix for this?

Could be wrong, but feels like every turboprop/shaft/jet/fan rotate same speed at start-up. Seems that it is inherit of FS and not aircraft specific., never actually thought about it before. At least aircraft.cfg does not specify start-up speed.

From videos and in person...I have noticed that it takes a few seconds for the props to start up to idle speed..but in the CS C130..its almost instant. I know there was a way to adjust the prop speed on another addon by editting the config file but I was wondering if this is something everyone else has noticed or tried to fix?

I guess you mean outside view. Props do go from stop to full speed in less than one second, but that is animation on model. Searched MS FS SDK, but didn't see any variables that could be set in aircraft.cfg to modify prop animations.
