Hi Mikael.

In the aircraft.cfg navigate to here:

[contact_points]
point.0=1,   51.20,  0.00, -11.45, 1600, 0, 1.323, 45.00, 0.6, 1.30, 0.6, 4.0, 4.0, 0, 230.0, 270.0
point.1=1,  -12.00, -9.20, -11.60, 1600, 1, 2.000,  0.00, 0.4, 1.35, 0.6, 6.9, 6.9, 2, 230.0, 270.0
point.2=1,  -12.00,  9.20, -11.60, 1600, 2, 2.000,  0.00, 0.4, 1.35, 0.6, 7.1, 7.1, 3, 230.0, 270.0

and increase the BOLD RED number. Try any number between 0.00 (no steering capability at all) to 180.00 (the wheel can be steered to 180^o).

Hope this helps

Mark
