Steering sensitivity

Good day!

I’m working on a fighter jet, as fast one, with afterburner, but I have some issues with it. One of which is steering sensitivity.

When I take-off, even the slightest change in yaw makes the aircraft shoot left and right and even roll over. The contact points for the wheels are set-up correctly so that shouldn’t be the problem. I’ve played around with all kinds of settings like rudder effectiveness, steering limits based on speeds, etc. but nothing seems to make it more stable on take-offs.

Can anyone maybe point me in the right direction into tackling this issue?
