Hi, can anyone tell me how to fix the problem of my wheels being slightly embeded on any given runway.
It only happens on one particular plane,"the Avro Shackelton ", that I downloaded from the vintage page of this site earlier tonight.
I have tried editing the Aircraft .cfg that comes with the plane with no luck.

Any help appreciated. Thanks.

Hi, the  line that I tried to make adjustments in read, "static_cg_height= 11.000 ", but no matter how much above or below the aforementioned value I entered , It just would'nt sit on the runway.
Has no effect on take-off or landing may I add, but spoils the overall effect of the model .

Nooo!  Put that figure back to what it was - see the last bit below.

This question is asked so often by Noobs  ;) here's what I keep on file...

OK, open up the relevant aircraft.cfg file with Notepad or Wordpad and scroll down to the [contact_points] section.

Here's a bit from one of my Mike Stone Airbuses

[contact_points]
point.0= 1.000, 38.000, 0.000, -8.000, 1181.100, 0.000, 1.250, 55.920, 1.000, 1.000, 0.900, 4.000, 4.000, 0.000, 0.000, 0.000
point.1= 1.000, -5.000, -11.600, -8.200, 1574.800, 1.000, 2.000, 0.000, 1.000, 1.000, 0.900, 7.000, 7.000, 2.000, 0.000, 0.000
point.2= 1.000, -5.000, 11.600, -8.200, 1574.800, 2.000, 2.000, 0.000, 1.000, 1.000, 0.900, 7.000, 7.000, 3.000, 0.000, 0.000

point.0 is the nose gear and points.1 and .2 are the main gear wheels. The fourth entry on each line is the position of the contact point below the aicraft's reference point. Increase the number, the plane will go 'higher' above the ground, decrease it and the plane will go 'lower'. Mostly I think you want the plane to sit just under the surface so the tyres look flattened by the weight of the aircraft.

BTW, here's something else you might like to know.

At the bottom of [contact_points] you have these 2 lines

static_pitch= 0.620
static_cg_height= 7.800

The figure shown in blue is the plane's 'start' position when you start the program or load that scenery. If it is too big, when the scenery finishes loading the plane 'crashes' to the ground. If it is too small, the plane starts with it's wheels under the ground and 'pops up'. It's amazing how many designers get the figures wrong and you need to adjust them.

Hope this helps.

You re bang on Rollerball, thanks for taking the trouble to reply.
Although the Shackelton had seven contact points that could be edited , I managed with your brilliant info, on just my second attempt.
The plane sits perfect now and looks the part.

Thanks for the help.

You're very welcome

D'ya know what - that was more or less the same question I first asked when I joined the forum back in ... well back a while now.

I remember good ole CalB answered it for me then - he's still around too and hopefully will be for a good while yet
