Hi there,

I have spent years trying to find a POSKY 747 that doesn't have the taxiing problem, and I finally found one at:

https://www.fs-freeware.net/downloads/download/52-civil-aircraft/2723-fsx-boeing-747-400-multi-livery-boeing-747-mega-package-vol-5.html

However, the nose comes down far too low, after not changing anything in the CFG:

Compare this with another POSKY 747 I downloaded, but this one slides while taxiing:

The contact points sections are below:

Any help is greatly appreciated.

Here are the contact point adjustments if you want to see if it will help.

I don't understand what I need to change. This is just the description of what each contact point does.

It is the description of what each section, between the commas, of each contact point does and effects the function of each wheel  and gear section.

You should be trying to lessen the compression of point.0

Well, after a bit of trial and error, I have found the right contact points.

If anyone is interested, these also fix the sliding while taxiing issue.

Thanks for your help 🙂

Hi r22s7,

Glad you mentioned the too low nose gear issue of the mentioned distribution of the wonderful POSKY Boeing 747-400,

and for sharing your contact points!

The contact points you provided seems to be working fine for the 747-400 (Pax) and 747-400BCF aircrafts.
What I find strange is that point.0 and point.1 have different values for the eight and ninth parameter (0.0, 0.0 against 0.3, 0.5)

One would assue that the values are should be the same for the 2 nose-wheels?

Or am I mistaken here?
Many thanks in advance for replying to my post.
