I got a plane that bounces too much on landing, even when I put her down ever so gently. Can this be cured /adapted in the cfg file or is it in the air file?

What aircraft, Cees? Is she a tail-dragger or tricycle gear?
It's a taildragger and it's the Fokker C-X I'm converting.

What sim version?? FS or CS etc??Quote:

OK - you likely can edit the aircraft.cfg file in the contact points section, probably the damping ratio of the main gear. It controls the "springy-ness" of the landing gear at touchdown. For your taildragger it normally should be lines 2 and 3 (MLG, line 1 is the tail wheel), but the order can be different, though I have never seen it.Quote:

Further searches and experimenting will likely solve the problem (be patient). Also, set up a saved flight starting with a short final on speed and altitude. Reload and test will go much quicker.
Not always a problem with taildraggers depending on the model but landing fast, or three point rather than on the backside of the mains can be a problem. DC-3s are a typical example.
The aircraf.cfg section of the FSX/ FS2004/P3D SDK's have a great breakdown of the various parameters and what they do.
Cees,
If you use ACM (Aircraft Container Manager) you can have a visual guide to the aircraft. It's available over at Simviation.
Since the model is FS9 originally, you can do the changes in ACM and then just copy/paste them over to the cfg for the FSX conversion using Notepad or something similar on the cfg file itself. The format is the same between the two.
Some points to keep in mind with ACM:
1. Zooming in/out is done by holding down the middle mouse button and sliding the mouse left/right. Can't use the roller. Takes getting used to, but not bad after a while.
2. The best way to reset the contact points and scrapes (that I've found, anyway) is to reset the CG altitude and the Angle to "0" and work on the wheels from there.
3. The static compression can be anything, but I've found that static compression at 0.25 and the ratio at 2.5 works well.
4. For the oleo (shocks) I tend to use between 0.65 and 0.75, but any number less than 0.85 and greater than 0.5 seems to work well depending on how much "bounce" you want to have in the end.
5. When lining up the wheels for the angle and cg height, remember to use the "light blue" points and NOT the main, "yellow" points. When you load up the aircraft and begin to mess with the points you'll see what I mean. The "blue line" is the cg height and should bisect the "blue points" that represent the aircraft sitting on the ground/ramp.
The reason I mentioned this method is because all the points and cg and angles for the aircraft sitting on the ground have an interaction with each other. If you change one or two it may have an affect on the others, though sometimes you can get lucky.
It's worked on the updates I've done so far. It shouldn't have any adverse effects on handling if using the default air file that comes with the aircraft since it's just changing the contact points.
Good luck!

It's just something I slapped together tonight, so haven't had a chance to try it out yet. It looked good in ACM, though.
My formatting gets hosed on the board, but the numbers should work. It just doesn't look as "tidy" as it does in my cfg file.
I noticed the CG position was at -1, 0, 0 in the cfg file, and the aerodynamic stuff (wings, empenage, etc) were a bit aft of where they were in the actual 3D model.
The CG position sometimes - not always - affects the way the contact points interact in the sim. I know in a real aircraft it's always the case, but it's been hit-or-miss so far with FS9. Maybe FSX is a bit more realistic?
Anyway, I can take a better look at it after work tomorrow if you would like and get you something you can better test in FSX by Saturday, but for now this should be good enough to see if it basically works.
Good luck!

Cees, As Jorge pointed out above, its usually the contact points compression ratio (//9 Max/Static Compression Ratio).
In FS2002 and FS2004, its my experience that if the ratio for each "point" is greater than 1, the gear acts like a launch pad cannon when you try to land. :dizzy:
I'm not sure why there are so many aircraft out there with hairy compression ratios, but I'm guessing its more normal for FSX?
One thing you could check (I don't run any of the FSX series) is look at the .cfg file for a stock/default tail dragger and check that 10th variable for a good/better comp. ratio. :wiggle:
I was planning to start a [contact points] thread in the FS2004/FS2002 forum if you folks want to dive deeper into it.
If Jorge wants to be a part of it, that would be even better. :wavey: There's a lot of info to cover.
Count me in! :ernaehrung004:Quote:

I have a feeling the CG's position is going to be a contributing factor in this one since it's longitudinal position is -1 and the wing's longitudinal position is aft of the 3D wing's one. That may work great for a custom air file, but somehow I have a feeling that this particular custom air file may not work too well in FSX. I hope I'm wrong since I know it takes a lot of work to get those things right, which is why I usually take a default one and "tweak" it with the cfg entries.
I'll check on the CX later tonight after work, cooking dinner, etc. :a1089:
I'll report on whether it bounces in FS9 after the changes. If it doesn't, then it should be okay in FSX. If it does bounce, then I'll have to look at it with more detail in ACM to see what can be done with the CG and the aerodynamics.
Fingers crossed!

Cees,
Looked at the thing tonight.
Seems everything was connected together -- CG, contacts, etc.
Worked on it for a little while and came up with the following which seems MUCH better than the default. Let me know how it works on your FSX installation since I've done it in FS9:

//========================
I basically just kept the air file that came with it and tweaked some things in the cfg file after running it through ACM first. I basically have a template I use to update the cfg file. I just comment out what I don't need. Helps when messing with Whittle, Me262, Salamander, and the like since I don't have to look around the SDK for jet stuff.
I think the AirWrench stuff from the original cfg file over-wrote my comments in the prop section, but the plane handles similar to the original upload. It just doesn't bounce all over the place.
I also found that I get a nice "wobble" when idling the engine on the ground in the VC if using active camera. Not sure if it will do the same with the FSX version of the head shake. The wobble goes away with power added. I noticed the same thing with the Northrop Alpha update I did a while back, but I thought it was something I did wrong. Turns out it may have to do with separating the engine from the prop location. Now you can make it feel like you're in an airplane with an engine running!
Let us know how this works with FSX!

That is so much better! I only had to adjust the height of the contact points. The bouncing is gone! Thank you so much!
