Try taxiing slower. That aircraft can speed up sooo quickly. And plus it is a aircraft for speed so just take your time taxiing and sometimes turning off autorudder control if you have a joystick which has the twist handle. I say this because sometimes not alll the time but sometimes that really helps in turning the plane effectively.
FS2002 but I highly highly suggest upgrading to Fs2004 ,now adays FS2004 is being sold for almost near free...and for cheap. So I suggest you take the jump. Since FS2002 which is damn near obsolete wont give you the flying experience you want. Try flying a plane in Spot View mode. Its very hard. So as I said FS2004 is the way. I'm not forcing you but by all means your missing out.
