This is my first post here, so hello to everyone

My name is James and i live in Edinburgh, Scotland.
I just bought FS2002 Professional Edition (it was a bargain, or at least i think it was at 25quid) at the weekend and have been tinkering around with it.
I have also just ordered FS2004 and a Saitek X45 joystick from Amazon (was that a good joystick choice??)
Anyway, the only way i can control the game at the moment is with the keyboard and a Microsoft Sidewinder gamepad, the problem i have is that i adjust the aircraft trim (any aircraft) so as i have perfect level flight, but, as soon as i make a turn or adjust altitude my aircrafts trim seems to completly change leaving me heading for the ground after every manouver. Is this a problem due to my control methods?? or is this considered normal?? (hope not

Also, another thing i have noticed is the lack of the Forth Bridge (rail) when you take off from Edinburgh airport, this is quite dissapointing as they have taken the time to include the road bridge, but not the bridge that really matters. Is this fixable?? or is it included in FS2004.
I would appreciate any help anyone can give me.
Regards to all,
James.
