Alright. So I installed this Mi-24 Hip helicopter, but when I start it in the game, the engines are off and they won't start. How do I fix this?
If it's this one https://flyawaysimulation.com/downloads/files/2765/fs2004-mil-mi-8-mt-t/ then the problem is on your end. I just installed it and the engines were on.
Try another aircraft or helicopter you know how to start the engines and then switch over to the Mi-24 - this usually works.
