cant keep it straight?

howdy all flight sim'rs

this is my first post blahhh blahhh.....

anyways i have a annoying problem when trying to take off,
basically whenever i power up the engine/engines release the brake my plane always veers "strongly' from side to side like on its own as if i were giving it full rudder left then right then left........ i struggle to keep it on the runway always counter steering with the rudder? once the plane is airborne its fine?

at this point i should mention that im using the xbox 360 controller and my rudder is set up to right analog stick left and right.
Ive lowered the sensitivity a little with little of no effect?

also as i mentioned im on the xbox 360 pad i would also like to know how or if its even possible to assign throttle to analog stick? im a bit of an rc nut and have been trying to set up the 360 pad as if it were a rc radio transmitter in mode 2 i think its mode 2? throttle on the left. as i like to fly my G-SUSX police md 902 chopper around from the tower view and spot plane view.

cheers hank!

no ideas chaps????? its driving me nuts.

I have the same problem. All of my aircraft, to a varying degree, pull to the left or right (L>R). I checked my autopilot - not on, so that wasn't the problem. My guess is that it's the natural torque of the aircraft. If so, I can do w/o that piece of realism!

yeah me too bud, but thats surely not the case airline pilots fighting with the controls?? i really have to work hard to keep it on the runway, all my take off look real messy from the tower view!

In reality, if we take a single engine "prop" aircraft with the prop turning clockwise as viewed from the cockpit...................the airplane will start pulling to the left as you move down the runway. The pull is constant (as in.. doesn't go away), and you'll be pushing right rudder against that pull all the way down the runway, as well as initial climb out.
The amount of left drift will depend on airplane design, and power to weight. We've got up to three forces pulling here. Propeller slipstream, torque, and P-factor

Some simulated aircraft do get "wishy washy", and seem to drift one way or the other, or all of the sudden, the drift force will just seem to disappear, and it will wander the other direction. Personally, I use rudder pedals. I don't like twist grips, rocker switches or keys, as they seem twitchy.

A lot of simulated airplanes do drift to the left, including defaults. Sometimes, in my opinion, the effect isn't strong enough. It was better in FS2000 & Microsoft's Combat 1 & 2.

And in reality, the pull to the left varies with power to weight, rudder sizing, and a few other variables. Engines may be installed with an angle to the right, as well as a built in offset in the vertical stab. And then you'll have fixed rudder tabs as well as adjustable trim tabs to counteract the force at cruise speeds.

Generally, a simulated jet should track straight. Same with counter-rotating props. Props that turn counter-clockwise (viewed from cockpit) will require left rudder.

That's all true, but FS2002 has some kind of bug, which causes most planes to veer left (a few to the right) even when taxiing or coasting at low to no power with rudder "centered". Even jets. The FS2000 Concorde, for example, taxis like a WWII tail-dragger fighter (S-turns all the way, will not go straight with even single taps of the rudder keys). Unfortunately, the rudder trim does not affect taxiing/rolling on the ground at all, so for some aircraft it's simply impossible to make them roll straight through normal controls. Also, analog rudder controls (pedals, joystick twist, etc.) do not have any less granularity than the keyboard controls -- for a properly calibrated setup, slowly moving the rudder control a small amount to one side or the other will at first have no effect, leaving the control surfaces "centered", then once you've moved it far enough, the control surfaces will behave exactly as if you had tapped the corresponding rudder key once.

I can't find anything in the *.air or aircraft.cfg files that affects this, so I'm guessing it must be either a bug in the software engine, or an over-sensitivity to any slight asymmetry in the 3-D model.
