Taxi steering oversensitive - small fix

I find the ground steering to be over sensitive.

To remedy this issue I have made the following change in the Aircraft.cfg:

Original setting:

[contact_points]
point.0 = 1, 14.4, 0.0, -4.7, 1600, 0, 0.6, 96, 0.50, 2.20, 0.7, 3.0, 6.0, 0, 195, 195 // FS 30

Changed to:

[contact_points]
point.0 = 1, 14.4, 0.0, -4.7, 1600, 0, 0.6, 50, 0.50, 2.20, 0.7, 3.0, 6.0, 0, 195, 195 // FS 30

The original setting of the steering angle=±96° makes no sense for me.

The real plane can turn on the inner main wheel (Info by Ken) and that why it is set that high. Too me the oversensitive ground reaction comes from a lack of inertia.

Can the lack of inertia be changed via the contact points or is that in the flight model?

While that might be accurate IRL, this doesn't work great in P3D (FSX) where ground handling isn´t that great simulated, maybe due to the lack of inertia and strange ground friction.

But imagine the nosewheel turning 96° !! - thats the nosewheel standing acroos the nose and then further 6° -which again would be just 6° in the opposite direction. So maybe 96° is the total wheel steering angle from extrem left to extrem right - meaning that it rather should be at ±48° ?

I changed it to 50°, cause thats appr. where most other twin engined middle sized aircraft has it set to, including the Flight1 KA.

Taxiing is now managable and it still can turn quite sharp with the combined use of differential braking and nosewheel steering.
Using differntial braking would never require a steering angle even close to 90°.

Lock to lock is indeed a total of 96º, that is +/- 48º.

So the value should realistically be set to 48° I guess.

Based on that it would require more like the 50° that Finn suggested. I gonna put 48° in and see if the plane is still turning on the wheel.

Edit:
I changed the steering angle to 48 degrees. With that and full rudder, the plane turns on the on the inner wheel with a bit of forward rotation. If you brake on the inner wheel it turns on that wheel.
Steering during taxi and take-off is much easier and softer in the transition from ground steering and rudder steering. For me a better solution.

Ditto here changed to 48 and the steering feels smooth. Note I have no RW KingAir experience but feels nicer!

I will fix
