Thanks for the suggestions. I am already on the closest in hole at the servo, and the control horn only has one hole right at the end. Mind you, compared to your 2 1/2 inches, I think my control horn on the nose wheel is just an inch.

I've found if I just go to full throttle straight away on take off and hold some up elevator I seem to avoid the point where the steering becomes almost unsontrollable, so I guess I can avoid the problem, but I might look into replacing that control horn on the nose wheel following your instructions.

Thanks!
