There is a problem with the BF1's cockpit camera; it's way too unstable. Maybe that's there to simulate the g-forces. If so, it shouldn't be that crazy in real life. Whenever I race with the BF1 I have to switch to the camera after that (just shows the tires). The cockpit camera needs to be stabilized because, most of the time, I cannot see where I'm going.
The BF1 is a manic vehicle indeed, and the forces exerted on a driver in an F1 car are some of the most extreme forces exerted on anyone outside a MIG-29.
I recommend reducing, or even eliminating, the virtual movement of the camera view in LFS. Go to Options > View and find the following options. Play with them until movement is more to your liking.
O/T: What makes the MiG-29 so special? The F-22 is far more advanced and more manuverable. The F-16 is another that can certainly hold its own in a turning fight against a MiG-29.
Although the tumbling is impressive from an aerobatics standpoint, I fail to see how that might be useful in a combat situation. You basically take all of your energy and blow it all away, at which point you're a sitting duck.
While another fighter on Su-35'a tail is trying to lock on it, such manuverability can alow su-35 to go out of the target range of the enemy quicker but also can allow u 2 slow down more progressivly than the enemy which allows you to become a hunter
Ofcourse the don't have to make double 360's in one place at combat conditions, but it allows the plane to change directions much quicker
There are much more reasons for it, but I don't know them all
That maneuver probably helps pointing the nose more than anything... like reversing positions. I think modern missiles only need the target generally in front of you to work.
Anyway, if fighters are forced to make high G turns the pilot's done something wrong, because he should have found the target farther away and shot it down already, OR he shouldn't have gotten missiles on his tail.
Now the RedBull air race is where pilots regularly pull 9G's. They've truly got nerves of steel. http://www.redbullairrace.com/
Fighter's radar only scans the area infront of the plane. As Forbin said, doing such manuver is quite pointless in combat conditions cause the plane will glide were slowly which makes it extremly easy to lock on and destroy as the fighter just won't be able to outmanuever the missle.
Like I said, Su-35 has extreme manuvarability, but it doesn't mean that pilot has to use all of it every time. As for G-forces...Pilots are always dealing with G-forces and there is nothing wrong with it. If he will be trying to turn around with low G's he'll be dead in 30 sec.
However your thought makes sense when we talk about Commercial airliners Imagine people in the Boeing 777 flying all over the plane periodically being sqeesed to the floor under 9 G's (the plain would fall apart under 4 irl but still fun)
