Planes never take off straight

[Stealth2668]

For some reason, 90% of the time when i build a plane and try to take off, it pulls to the right and i end up crashing. I always build with symmetry so there shouldn't be any imbalances. Is this a glitch or something?

[Sir Nahme]

your vertical tail piece is probably causing your center of lift to shift slightly to one side. I've noticed this on quite a few of my aircraft as well until I stopped using parts that provide lift for them

Nope, its because either it started to tilt, and ended up unsymmetrical because of this, or you thought that what your where building was symmetrical, but it wasn't. If the wheels are tilted, this will happen.

Landing gear at an angle has weird physics, and is completely unreliable. That may be your problem. To be sure, show us a screenshot of an example of a defective plane.

Ill upload pics tomorrow if i remember. At work till late right now.

If you have a single nose wheel, and lots of force on that wheel, very small asymmetries in that force will cause you to swerve. You can mitigate this by putting your nose wheel such that you start pitched down slightly, and thus it will tend to come off the ground quickly. This may or may not be your problem.

Yup i've noticed this as well. Also if the front wheels are higher or lower than the back ones.

Also on a side note. Is that dog in your sig named Laika by chance?

I have the same problem, but mine always pull to the left. I was told it's a flaw in the floating point calculations which causes this instability. The easiest thing you can do is put four wheels on instead of three.

Make sure your wheels are pointing STRAIGHT forward not off one bit... Used to happen to me all the time.

[SecondGuessing]

The usual reason for this is the tail of the craft lifting before the nose, resulting in a plane that is balancing on one wheel - a situation that will never end well.

Wouldn't this mean the air would push me down since the wings will be pitched down a bit?
