Move a plane with joystick

This is probably a really simple task that I’m having issue with.

All I’m wanting to do is move a 2D plane object in the X and Y axis depending on how my joypads thumbstick is pressed (can’t use a GUI texture, as it needs to be a plane. Too long to explain).

When I run my game, my plane moves miles away as opposed to the movement I want it to do. Right now, the code I have attached to my plane is as follows:

The update method

xMin1 += Input.GetAxisRaw("LeftRight");
yMin1 += Input.GetAxisRaw("UpDown");

// targetPlane is a public game object   
targetPlane.transform.position = new Vector3(xMin1, yMin1, 2.5f);

Is there something I’m missing, or doing just completely wrong?
As I said, all I’m really trying to do is have a plane move in either the X or Y axis, in front the camera , depending on how the joystick is pressed.

I’d appreciate any help that you can give.

xMin1 += …
Every frame xMin increases by the joystick value, frames can go up to a few hundred times per second.
try multiplying Input.GetAxisRaw(“LeftRight”) by Time.deltatime === joystick value unites per second, instead of per frame
