Hi everyone,
I was wondering if anyone knows how to sort this problem, I haven't noticed this before so I asume this must be a new problem, sometimes when I start up at an airport this happens-

It's not just this plane and I can sometimes sort it by changing planes and chaning back but its still extremely annoying, this time it didn't work. Any Ideas?

Hi Bird man. I've only experienced this when messing around with the [contact_points] entries on my own stuff. This particular aircraft looks a tad tail-heavy to me. If you're familar with editing Aircraft.cfg you could try moving the main gear positions back a little.

Another little trick is to hit the Y key & see if that fixes it.

PS. Just a thought. Are the engines running when the sim loads? If you recently changed it to a cold start that might explain it.

Umm

, I don't think i've changed anything recently, but I have put fuel consumption on Roll Eyes

- and damage Roll Eyes

, that could have done something I suppose Embarrassed

.
I've also not altered any scenery, (or whatever 'contact_points' are! ???)
I'm pretty sure its not the aircraft, ive had it for a good while now and I know it pretty well as i've probably flown it the most Roll Eyes

. look at this though-

Grin

Slewing doesn't help Sad

and the engines are running when I start.

What a shame, thanks for the ideas Hagar.

Ah, I think the damage explains it. Seems the gear suspension isn't strong enough. The [contact_points] entries define the gear in Aircraft.cfg. Open a default Aircraft.cfg in Notepad for an explanation. Each problem aircraft would have to be tweaked individually to fix it. It's a tad complicated & could take a little figuring out if you're not used to it.

Maybe use the original default flight at Meigs. Then change aircraft & see if that helps.

PS. My tute here explains the problem. http://www.simviation.com/lair/Sinking.htm
It will only definitely fix the aircraft used as an example but might give you an idea of where to start.

PPS. Think I found the Frontier Airlines DC-3 in your shot. I used the variable from the CFS2 default C-47 & it seems to work fine. Try changing the entry mentioned in my tute to 0.44 (instead of 0.2). Here's the complete line.
point.0= 1.000, -38.417, 0.000, -0.833, 1574.803, 0.000, 0.666, 57.660, 0.44, 2.500, 0.916, 33.000, 33.000, 0.000, 0.000, 0.000

I'll have a fiddle with the tomcats contact points in the cfg file 8) (I think there should be a smily thing with a chainsaw just for me!!! Wink

Not quite, it's the sign of a misspent old age. Wink

It's usually a matter of trial & error + a lot of patience. If in doubt, refer to the defaults.

Please tell me if my tweak worked for you on the DC-3. Don't forget it will be the main gear you need to look at on the F-14.

8)

???

Hasnt worked. Wink

Are you sure its to do with 'contact points', as sometimes the wheels work fine ???
I have been doing a bit of touring so I may have landed at an airport, saved and restarted it another time and it may have figured that id broken them on my landing, my landings aren't always too great.....................................................................

Ha Ha. Any other suggestion?

Is this happening at the same airport or any of them? Some airports have some anomolies in their runways which is why I'm asking,

I could only duplicate your problem with the DC-3 by taxying it over rough ground. Tweaking the tailwheel as I suggested fixed it.

This might be the answer. If you save a flight with the gear damaged it will start with the same settings each time you use that flight. Try setting up a new flight from CREATE A FLIGHT. Choose one of the default aircraft & airports. Meigs is good for testing stuff. The aircraft should be fine when the sim loads. Then change it to the DC-3 & see if that fixed it. I've almost run out of ideas. LOL

I think it fits, the problem occured at the same airport - but not always and the first time it happened I did drive over the grass Shocked

as it was quite late Wink

, so it could be the Airport, my driving over the grass Roll Eyes

Or do I understand Hagar that you downloaded the aircraft and had the same problem? But I don't really mind that much, ill just hop into a different plane for a bit. (I might even turn damage off as I seem to be crashing an awful lot.)
Thanks for the help,
