Ive got a helicopter using two speeds, Helispeed (pitch foward/back speed) and heliRollSpeed (roll left/right speed), But im trying to add a air resistance element to them so you start to slow down if you are leveling out the heli, But cant work out how to add this in well.

This is how i get the speeds (almost identical for ptich/roll):

```
pitch = heli.transform.eulerAngles.x;
if((pitch > 0) && (pitch < 90)){
float temp = (60 - Mathf.Abs((pitch - 45) / 0.75f)) / 100;
heliSpeed = heliSpeed + temp;
if(heliSpeed > 40.0f) { heliSpeed = 40.0f; }
} else if((pitch > 180) && (pitch < 360)) {
float temp = (60 - Mathf.Abs((pitch - 405.0f) / 0.75f)) / 100;
heliSpeed = heliSpeed + temp;
if(heliSpeed < -40.0f) { heliSpeed = -40.0f; }
}
if(heliSpeed < 0){
heli.transform.Translate(-Vector3.forward * -heliSpeed * Time.deltaTime);
} else {
heli.transform.Translate(Vector3.forward * heliSpeed * Time.deltaTime);
}
```

But the speed will always increase if you are not at 0 degrees. So i tried adding this to a lateUpdate

```
if(heliSpeed > 0.01){ heliSpeed -= (heli.rigidbody.drag / heliSpeed); } else if (heliSpeed < -0.01) { heliSpeed += (heli.rigidbody.drag / heliSpeed); }
if(helirollSpeed > 0.01){ helirollSpeed -= (heli.rigidbody.drag / helirollSpeed); } else if (helirollSpeed < -0.01) { helirollSpeed += (heli.rigidbody.drag / helirollSpeed); }
```

but without thinking, this just means you cant move in any direction, it just shoots you in the opposite direction.
