In small planes, like the Cessnas, during full power on take off, the planes always get pulled drastically to the left.  My joystick is calibrated, there is no wind, perfect weather.... any ideas?  Also, on bigger planes, like the 737, it goes left slightly.

Don't worry, this is called the slipstream effect.  Air disdurbed by the propellor gets pulled through it goes underneath the body of the aircraft and hits the tailplane on the left hand side thus creating yaw to the left.  It is something we pilots must counter all the time in real life using rudder but you could try reducing the realism settings slightly to counteract the effect.

In your realism settings just reduce the torque setting
Alas in real life this is what happens.

this is the exact reason why most twins spin their props in opposite (counter-rotating) directions.  Before aircraft builders figured this out and both props on twins rotated the same way, you got MAJOR pull to the left.  Just try the default Comet!

This is just the pull from your prop turning in that direction, it happens in real life too but is corrected by giveing a little rudder in the oppisite direction, if you don't like it you can just turn p-factor all the way down in options.

I need help I get the same thing. and the p-factor and torque are all the way down...settings are all on easy and i turned off aircraft turbulance and it all went away but now my plane drifts to the right...I got this on FS2000 as well. Could it be a preset ruder thing and now that everything is there is nothing fighting it and the plane goes to the right.

I narrowed it down to weather and clear skies....but why do i always drift to the right and the same speed, angle....

Simon. Try recalibrating the joystick or whatever controller you use. If there's no crosswind I suspect this is the most likely cause of your problem. It will depend on the type of aircraft. Jets should not be affected by prop torque or P-factor. Most of the default FS9 props would veer to the left, not right. On multi-engined types make sure that all engines are running before attempting to take off.

US engines spin clockwise (cockpit view).
All require TO check list trim settings.  Not given in sim that I know of.  Cessna mild so feed a little left rudder on TO roll.
BR engines counter clockwise.  Rt rudder trim settings esp Comet since both turn CC.  Must have a locked tailwheel.
My Comet settings: p_factor_on_yaw  =0.5    //was 1.0
