Rigidbody acting different on two different objects

Can you post your code?

Not that it will really help, because it shouldn't matter because it's pretty generic. But here it is anyways... I don't see what could possibly make it work different for a different model only.

There's literally nothing different whatsoever, it's only a different model. But here's the code. $$anonymous$$aybe there's something in there that could explain why just a model would react different do it that I'm just not seeing.

 public float speed;
     public float sideThrusterForce;
     public float yawSpeed;
     public float pitchSpeed;
 
     public Rigidbody myRigid;
     float decelerationTime = 1.0f;
 
     private bool airBrakes;
 
     private Health health;
 
     void Start(){
         health = GetComponent<Health> ();
         Cursor.lockState = CursorLock$$anonymous$$ode.Confined;
         Cursor.lockState = CursorLock$$anonymous$$ode.Locked;
         Cursor.visible = false;
     }
 
     void OnCollisionEnter(Collision col){
         health.DoDamage (10);
     }
 
     void FixedUpdate () {
         myRigid.velocity = Vector3.Clamp$$anonymous$$agnitude (myRigid.velocity, speed);
         if (!airBrakes) {
             myRigid.AddRelativeForce (Vector3.forward * speed);
         }
 
         if (airBrakes) {
             myRigid.AddRelativeForce (-Vector3.forward * speed);
         }
 
         myRigid.AddRelativeTorque ((Input.GetAxis ("$$anonymous$$ouse Y")) * yawSpeed, 0, (-Input.GetAxis ("$$anonymous$$ouse X")) * pitchSpeed);
 
         if (Input.Get$$anonymous$$ey ($$anonymous$$eyCode.A)) {
             myRigid.AddRelativeTorque(0,(Input.GetAxis("Horizontal") * yawSpeed * 2),0);
         }
         if (Input.Get$$anonymous$$ey ($$anonymous$$eyCode.D)) {
             myRigid.AddRelativeTorque(0,(Input.GetAxis("Horizontal") * yawSpeed * 2),0);
         }
 
         if (Input.Get$$anonymous$$ey ($$anonymous$$eyCode.W)) {
             myRigid.AddRelativeForce (Vector3.forward * speed * 3);
         }
 
         if (Input.Get$$anonymous$$eyDown ($$anonymous$$eyCode.S)) {
             airBrakes = true;
         }
 
         if (Input.Get$$anonymous$$eyUp ($$anonymous$$eyCode.S)) {
             airBrakes = false;
         }
 
         if (Input.Get$$anonymous$$ey ($$anonymous$$eyCode.Q)) {
             myRigid.AddRelativeForce (Vector3.left * sideThrusterForce);
         }
         if (Input.Get$$anonymous$$ey ($$anonymous$$eyCode.E)) {
             myRigid.AddRelativeForce (Vector3.right * sideThrusterForce);
         }
         if (Input.Get$$anonymous$$ey ($$anonymous$$eyCode.Space)) {
             myRigid.AddRelativeForce (Vector3.up * sideThrusterForce);
         }
         if (Input.Get$$anonymous$$ey ($$anonymous$$eyCode.C)) {
             myRigid.AddRelativeForce (Vector3.down * sideThrusterForce);
         }
     }
 }
