    Just when you think you have everything running some what better...

    You get a message from the Hosting company. Short story they need to move us to a new server. I have been working with them to plan a good date for all concerned. Here is what we have come up with as a schedule.

    1. November 4th 17:00 -5UTC shut off the forums and start backup proceedures. During this time there will be no access to the forums or the Resource Section.
    2. November 5th Continue with Backups and download same until complete.
    3. November 6th 7:00 turn over server to hosting company to move system to new server
    4. November 7th - 8th restore backups and upgrade forum software.

    If all goes well we should be back online on November 8th.

    To keep you updated we will post updates on AVSIM forums.

    Thank you for your support.

Track steps of playable vehicles on the ground

Is there an idea, how you can change the distance of the track steps on the ground from playable vehicles you see when driving forward ?

I think perhaps change something in the aircraft.cfg ?

I remember there was a advice in forum some weeks ago.
 
It's all about the width of the contact points for the undercarriage in the cfg file. I presume the effect is linked to the point at which the wheels touch the ground. Of course, in driveable vehicles the wheels described in the aircraft.cfg are invisible but they can still have effects attached to them.
 
Some aircraft cfg files have the labels on them, to show which lines in the Contact Points are for the undercarriage.

Each contact point has these parameters:

//0 Class
//1 Longitudinal Position (feet)
//2 Lateral Position (feet)
//3 Vertical Position (feet)
//4 Impact Damage Threshold (Feet Per Minute)
//5 Brake Map (0=None, 1=Left, 2=Right)
//6 Wheel Radius (feet)
//7 Steer Angle (degrees)
//8 Static Compression (feet) (0 if rigid)
//9 Max/Static Compression Ratio
//10 Damping Ratio (0=Undamped, 1=Critically Damped)
//11 Extension Time (seconds)
//12 Retraction Time (seconds)
//13 Sound Type
//14 Airspeed limit for retraction (KIAS)
//15 Airspeed that gear gets damage at (KIAS)

The information about which line in the contact points section applies to undercarriage, is probably in the Aircraft and Vehicle SDK. Sorry, I am running out of time time to look.
 
The Aircraft Container System SDK states on page 14 that the first entry is the one that defines the class ('type') of the contact point:

0= None
1= Wheel
2= Scrape
3= Skid
4= Float
5= Water Rudder

So if you open your .cfg, look for the contactpoints that start with a '1'.

If we take the two lines below taken from an aircraft .cfg file as an example, you can see that the first one is a wheel, and the second one is a scrape (a contact point used to define where parts of the aircraft touch the ground when making a wheels-up landing):

point.0 = 1, -19.120, 0, -3.6211945, 2165.354, 0, 0.551, 180.000, 0.327, 2.500, 0.39, 4, 4, 0, 164, 184
point.7 = 2, -22.020, 0, -1.90, 3000, 0, 0, 0, 0, 0, 0, 0, 0, 4

You can also derive from the info that Daiwiletti gave that the wheel probably is a tail wheel (Y=-19.120, X=0 and Z=-3.6211945) and the second one a tail scrape: Both are way back from the centerpoint (Y-value) but on the centerline (X-value) and relatively low (Z-value)
