I've never really had a problem maneuvering. Right now I'm in a Tahayash S66, which looks like it would handle like a pig, but I'm doing pretty well - I have over 50 kills. I suspect, as Ahl has said, that it might be your controller sensitivity.
Do not follow where the path may lead. Go instead where there is no path and leave a trail. - Ralph Waldo Emerson
i have the game on PC as well, but after the tutorial i had to switch to a controller (i only had an xbox 360 controller but it seems to work just fine)
after you try both the keyboard/mouse then the controller you'll notice that this game was coded with a controller in mind having said that, are there some out there that can work K/M better? probably, but it just feels more natural in the cockpit of these ships to me with a controller.
and yes, even with the high sensitivity, i could hardly fly with K/M... just lucky i didnt get pirated at that time i guess
It makes perfect sense if you think about like a crazy person!
