I don´t know, how difficult it is to down the AI Mig-15 in Sabre. Still not sure about buying it,...BUT...I think it´s always good, to have a solid challenge in the sim. Well, it´s hardcore and it should be challenging. Almost every time I buy some module, I hate myself, because I suck badly at it. And I mean BADLY!
But DCS is a study sim. I love helicopters and it, of course, needs a lot of time to get used to, to learn to anticipate its movements and so on.....for first few hours, I juggle that shit all over the place. It´s like the pilot is having a seizure or something.
And that is the beauty of the simulation. Getting better, knowing more about the aircraft or helicopter, getting it in the hands, starting to use proper procedures....
So if You suck at dogfighting and You don´t know, what is wrong....dig the net. Look at YT or right here in the forum. People always chit-chating about all kinds of stuff and already now, You have a lot of amazing (good job, guys) examples, how to trash that Mig.
Damn that´s long...:)
