Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:
- Tag FS2020 specific questions with the MSFS2020 tag.
- Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
- Questions about aircraft design can be posted in the Aircraft design forum
- Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
- Questions about terrain design can be posted in the FS2020 terrain design forum.
- Questions about SimConnect can be posted in the SimConnect forum.
Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.
By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

Bill,
Tom was right.
Why not publish what you first tried, just the contacts data and CG positions and say what type of aircraft it was.
That way it will get fixed and both you and others will learn how to avoid this type of issue in the future.
Just fiddling and hoping for success is not a path to learning.
Sorry if this sounds pompous, I just believe the purpose of this site is to learn from others

A friend of me had four main wheels, as contact points. A glider, with weels in the wingtips or so. It kept falling through the ground.

Good point, Roy. I'll see if I saved the file and post it. It would be good for me to know what it was. This is either the second or third time in this project alone that this has happened.

I deleted it.... 
I usually save them, but this one had me mad, so I deleted it. I had put in quite a few changes before I gave up. I tried quite a lot to adapt it.
Here is the Config file without the top aircraft and camera views 'before' I changed the data. Its from my Aerospool Dynamic project. This is 'before' adjusting the contact points. Perfectly running.
This is going from a tricycle to tail dragger.

I usually save them, but this one had me mad, so I deleted it. I had put in quite a few changes before I gave up. I tried quite a lot to adapt it.Here is the Config file without the top aircraft and camera views 'before' I changed the data. Its from my Aerospool Dynamic project. This is 'before' adjusting the contact points. Perfectly running.
This is going from a tricycle to tail dragger.

Sorry, I didnt save it, so you do not see all my work I did to adapt it. I think I should just say, this doesnt exist, as you do not see the point I got to when I pulled the plug on this config. I ended up going with the config from the Extra 300 and adapting that into it. I do not care for the snappy aileron input and shakeyness when you do maneuvers, but its functioning. I prefer a bit of smoothness, not chaotic sharpness.

If you're going from tricycle to taildragger, then the cg is going to be behind the main wheels instead of ahead of them, but what lots of us don't realise at first is it doesn't matter what the model looks like, it has no effect on how it sits on the ground (or flies...). However I'm sure you know that so I'll suck my eggs quietly in a corner!
Did you move contact point 0 (the nose wheel on the Aerospool) back to the tailwheel? You've probably also noticed that contact is duplicated and you have more scrape points than your max no. of contact points permits.

I did move it back. I also changed its position on the contact list to 3 instead of 1 (2 from 0). Fronts were 1.5 feet in front of CG, rear was under -12 feet back. Fuel at zero point CG, passenger 3 feet back. Wings and tail were fine. I tried commenting out scrape points, that did nothing. When I would click on Slew, just before it loads up, before it would crash into the pavement, it was like 1 inch over the tarmac, perfectly tuned in angle and height.

Tom, I was just fine tuning contact points on the new config, and found an odd one that was probably it. 4 feet back, 2 feet down. That was probably what did it. It was probably in the ground with the other config, with new landing gear above ground. But I had commented it out, so it should have worked then. hmmm...

Ok, Roy. Here you go. Trying out this set of airfiles as a template, same thing. Falls through the ground.
I tried quite a few tricks. Also lowered the landing gear one foot, etc. Nothing worked. Lets see what is making this baby fall through the tarmac.
Pilot is 2 feet back, fuel is at 0 feet from CG/Datum. Landing gear is 2 feet forward of CG, tail is 12 feet back. Landing gear weight is good.

Pilot is 2 feet back, fuel is at 0 feet from CG/Datum. Landing gear is 2 feet forward of CG, tail is 12 feet back. Landing gear weight is good.

From rough calculations, your static_cg_height should be nearer 4.4 feet. The model has wheel radius 0.5 feet, so the sim thinks the wheels are below the black stuff and assumes the gear is busted. Crunch.
There's a Wiki article on the basics if anyone's interested:-

Tom has found the main issue. The static position is where the sim places the airplane model if you load it in pause mode. Ideally this should place the wheels just above the ground. Then when you un-pause the plane will drop down a little, the gear will compress to its static compression and all will be well in the world.
Now in your case you have it such that the center of gravity is 3.1 feet above the surface and it is at a 12.5 degree nose-up pitch angle. At that angle the tail wheel will be about 0.6 feet below the main ones and about 2.1 feet below ground, and the main ones will be 1.5 feet below ground. When un-paused all will not be well in the world and the plane might disappear or start performing agonized leaps. (Love to meet the jerk who thought that one up, probably the same one that sends you to heaven in TacPack)
To fix this start by making
static_pitch = 10.0 and
static_cg_height = 4.6 (1.5 + 3.1) You might need a few small changes, but it is better to have it's static position with the wheels above the ground rather than rely on the static compression to do that after the un-pause.
On the subject of the CG. It should be at about 25% of the mean aerodynamic wing chord (MAC) This is set by the value of
"wing_pos_apex_lon = -0.4 //Feet, longitudinal distance from reference point, negative going aft" This means that the front of the wing is behind the CG by 0.4 feet, should be in front by about 1.2 feet. So change the -0.4 to 1.2. This will not affect anything on the ground, but it will fly better.

Interesting findings, guys. I have done this for many years and never knew this about the tires needing to be above the ground on startup. Thanks Roy on the Datum information. I do usually make that point my CG. The cross hairs of the scene in Max are always at CG on my models. Off to see if this works.

I increased the height of the landing gear and also increased the height of the CG from the ground. I increased the CG height continually so that when in slew mode, it would be higher and drop down to the ground. In all instances, the plane still goes through the ground.
Could it be the MOI's?

I doubt it would be MOI or the fact that your pilot's eyes are 1.9 feet behind his CG.
It is odd, what exactly happens when the plane goes through the ground? Does it disappear, does it dance around?
Got a picture?

I boot it up, saved flight file, should appear on the tarmac idling. When P3D finishes bootup, you see the plane above the tarmac, about a foot off the ground, falls into pavement, boom sound, sparks fly, then you see it from a distance away, 'crash' word at top left on screen, sparks flying, and plane is still sitting at proper angle, the top of the cowling and pilots head visible above tarmac.
Woosh sound, crash sound, done.
Its like there are no contact points for it and it just falls through, like when landing on a building that doesnt have a hard surface on the top.

Whoa there, pardner! Raise static_cg_height and the gear height values at the same time and you may just be jacking the same problem ever higher without fixing it.
I plugged your contact points for the gear only into a taildragger and raised the static_cg_height to 4.4 feet. With a little bounce the model sat nicely on the ground.
I then added all the scrape points. Same result. BTW, the MOI values affect flight behaviour, not settling on the ground. Usually.
