Recently I started to fly with helicopters a lot on Flight Simulator 2004. And I have noticed one quite unreallistic thing. When I start the engine on a helicopter, the blades start to move too fast, while in real life blades start to turn very slowly at the moment of starting the engines. In FS it takes like 10 seconds to start the engine and take off and in real life it takes a lot more longer, like 1 minuter or so. Is there any way to make the engine start time a little bit longer? I tried changing the prop_anim_ratio in the aircraft.cfg, but it only made the blades spin slower, but the startup time is still the same and obviously too short. Maybe there's some kind of setting in aircraft.cfg or the .air file that can change the situation. I don't know if I'm allowed to put any links in the post, but this is just an example of how much time it takes to start a helicopter.
