Contact Points?

[hooterg]

The nose wheel in one of my fixed gear planes is off the ground by a few inches when the plane is at rest on the ground.  Main gear contact with the ground is fine.  Been trying to fix it in the cfg and/or air files, but can't get it right.  I'm probably trying to adjust the wrong thing.  Any help?

Go back to the aircraft.cfg file and look at where it says static_pitch =

It is located close to the contact point section.

From what I see from you post, it seems that your wheels are not sinking and the aircraft doesn't seem to bouce around.

Therefore, my guess is that it has to do something with the static_pitch value. Increase or decrease the value to see how it goes.

For your case, this is as far as I can help you. I hope this helps enough for you.

Good luck.

In addition to what Katahu points out, another thing to consider is the static pitch value.  

This is the [contact.points] section of the C-182 and I've high lighted the static_pitch value.

using [lights] in the cfg file to highlight where the models contact points are set was a great idea I saw in a tutorial on the simcraft website.

makes aligning to contacts points etc very easy.
