Is it? I normally fight FAon in a Vulture, and I have no problem pointing my nose exactly where I want it. Using thrusters, I can orbit the target, and I can flip into a reverski just as fast as I can by flying FAoff (pitch up and thrust down, then reverse the throttle). I'm not good at PvP, but I don't lose all the battles. I consider the main reason I lose being that the other CMDRs are simply better than me. Btw. I use HOTAS.Only way you can get the nose pointing in a different direction to your vector.
To give OP some credit, PvP is hard, which is what makes it fun. Just accept the defeats and try and learn from those.
