Well let me putt it this way, im gonna show you a picture and explane how it works it UT04 and BF-Series. Here is the picture i made of how the curve looks for different vehicles:

Let's say you start from point A and you want to get to point B. In the start your speed is like 300km/h so you start to turn because you want to get to point B. The red line assembles the BF2/BF2142 Chopper/gunship and the blue line assambles the UT04 Gunship or Manta. At start you figure out that you want to turn so you start turning, the lines are one on another so you only see red first, but then the speed goes down for the BF chopper because it's starting to turn and the resistance of ari molucles does the resistence but it turns smoothly and you maintain still good speed while you turn. But in this case when it comes to the UT04 flying vehicle, which is the blue line, you are trying to turn and you can't turn cause the mass drags you forward and you slide, same effect as you would experience you if tried to drive a car on ice at high speed, so the only solution at this point is to lower your speed dramaticly, so dramaticly that you almost stop, turn and then continue the curve straigh ahead with no turns.
I prefer the function of the red line cause you do it at faster speed and lose less time, plus when you slow down to turn like the blue line does, you are in incredeble danger cause all air vehicles are very voulnerable. There are many weapons that are ery effective against all Air Vehicles so it's not very easy to ramain alive unless both pilot and gunner are pros and the infantry are total n00bs.
Comparing a tank that is very effective to a aircraft is a bad example cause tanks have very high defense amount which aircraft doesnt have. Plus in all videos i never saw the aircraft shooting, only driving over people and flying at very slow speeds, unless the official trailer video where everything made in like a movie and they are using the aircraft im talking about and seem not to have bad controls as the aircraft that im talking about.
If those vehicles from official trailer movie will be available and those gunship in every gameplay movie wouldnt be majorty as they seem to be now then i have no problems. But still i prefer the function of the red line then the blue line when you have to make a stop to turn.
