Space Plane Spins

[Lobo1544]

I have recently been working on a space plane capable of taking me to orbit, and I have run into a little problem. Everytime I take off of the run way, it twists to the right immediately. If i do not have my ASAS on, then the whole thing flips out of control, sometimes even when ASAS is on. Does anyone know how I can fix this?

By making center of mass and center of lift right relation to each other

This is usually due to landing gear not being perpendicular to the ground, either because it's placed that way, or because the weight of the vehicle is causing flexing.

Try rotating the landing gear with the WASD Q & E keys, with Shift pressed.

I'm not sure I understand what you mean. Also, it IS symmetrical.
