All my aircraft in both FS2002 & FS2004 start yawing to the left on take off.  I have tried everything to and sometimes succeeded in having them go straight down the runway, but it changes it seems for no reason I can understand when I work on other things in the computer.

Could anyone, having had the same problem which I have for the last 4 years, give me a hand on rectifying this situation.

All propeller-driven aircraft, both in real life and in FS, has a tendency to yaw left upon takeoff. This is due to the fact that all propellers rotate clockwise as viewed from behind. There are two effects contributing to this, the P-factor and the spiral propwash.

Obviously, the way to overcome this is to yaw right with the rudder. Another more simple way is to go to FS2002's realism settings, and drag the "P-factor" slider as low as possible.

Problem with the joystick?  I just replaced mine recently for a similar problem.

Does it still happen with auto-rudder enabled?

Also not knowing your level of experience/knowledge but many aircraft especially non-jet types have a tendency to swing left when full power is applied.  You have to correct with right rudder.

I once ran a real aircraft off the runway on takeoff because I was having trouble correcting for yaw.  That was the most embarrasing moment of my life.  I could just picture the tower people having a good laugh at my expense!!

It's a problem you may have to live with.  Rudder helps, you'll need a twist joystick of course, but it sometimes is sensitive, depending on the aircraft.  However, I've found that left brake/right brake techniques are easier to apply.  Check your assignments for the key assignments, I've reassigned mine and don't remember the defaults.

Not wishing to be pedantic or confuse things but this is not correct. The yaw will be in the opposite direction to the prop rotation. Many aircraft engines/props rotate anti-clockwise as viewed from the cockpit which would cause a yaw to the right. (For example: the DH Gipsy engines & Rolls-Royce Griffon) However, I think all the FS2002 default props yaw to the left.

This is not a problem if you have a joystick with a separate rudder function or yoke & pedals. Of course, it will depend on how you have the joystick sensitivity set up & will vary with different aircraft. It might be difficult to counteract if you fly with the keyboard only. I don't know how they manage but understand that many people do these days. If you use the keyboard only or a basic 3-axis joystick enable Auto-rudder from FS2002 Realism settings. You can then steer on the ground with the ailerons. Failing this, reduce the Realism settings to Easy to do away with the torque & prop effects completely.
