Lower turn speed the faster you go?

Unity Engine

I am making a Jet game, and at the moment the jet can go from 0-500mph now I need it so the faster I am going the slower the yawspeed is and the slower I am going the faster the yawspeed. But I cannot figure out get a suitable value based upon speed.

so something like this, without having to write if speed < 500 speed > 450 for each yawspeed
500 speed 1 yawspeed
450 speed 2 yawspeed
400 speed 3 yawspeed

Here’s my code

// set the max yaw speed
var defaultyawspeed :float = 20;

function Update() {

//prevent going faster or slower than 0-20
if (defaultyawspeed < 0){
defaultyawspeed += 1;
}

if (defaultyawspeed > 20){
defaultyawspeed -= 1;
}

// yaw left and right pitch up and down with mouse
function FixedUpdate() {
   	var h = Input.GetAxis("Mouse X");
   	var v = Input.GetAxis("Mouse Y");
   	transform.Rotate(0, v * defaultyawspeed,0);
   	transform.Rotate(Vector3.right, h * defaultyawspeed);
	}
}


// acceleration and deacceleration over time
function brakespeedlogic () {
	speed -= brakespeed;
	defaultyawspeed += 1;
}

function logic () {
	if (speed < maxSpeed) {
			speed += 1;
			defaultyawspeed -=1;
	}
}

Why not figure out a formula and just calculate it from the speed each time? Using good ole algebra you could pick 3 points on a graph and make a formula that fits it.

You can even use that calculator to find it. I’ve done your sample points above as an example.

Yaw = -.02 * speed + 11;

If you want to clamp that to min and max values, say, 1 and 5:

Yaw = Mathf.clamp(-.02*speed+11,1,5);

In general if you want a quick way to take some values and get a function that approximates the trend, you can pop them into Excel or Google Spreadsheet, graph them, and add a linear or other type of trend, display the equation.
