Hello Anders,
Yes you are right, after i moved the offset position, the plane do take
off without sinking into the ground.
But this give rise to another issue, as long as i am on external views
(eg chase, fly by views), it renders as if the CG is at the tail. When i

Thank you Adrian,
You have much cleared my doubts in YASIM with regards to contact point
issues.
As for Gears sinking into the ground, even adding a fake gear was not
much of a help.
Later i got reply from Andres and he was mentioning the origin offset
could be the cause and he seems right on

Hello All...
I am trying to better understand how YASIM calculates its contacts
points
1) As from my experience, the SIM crashes when some part of the wings
comes in contact with a building or ground and it does not crash if
other parts of the wings hit the ground of a building.The wing

Hello,
So I tested the bo105 now with the HudsonBuild 262 win32-installer (before
YASim-patch) vs. the latest HudsonBuild 272 win32-installer. (after
YASim-patch)
I used the Bo105, KMTN, rwy15

Hello Heiko,
does your local FDM still uses default approach fuel etc? But even if
not, there should be no difference in the flight behavior. The only
effect of the approach fuel level is (for a rotorcraft) within the gear
solver.
By the way: I would prefer to use the old default values for th

I have tested it, and well, at least for helicopters there seems a difference.
No idea how long we have this bug now- but I guess a very long time.

Ok success. It does rest slightly off the ground at the nose ... i
removed the fake gear and all the mstab objects (clever use of mstab ,
by the way :)) , and still the same results... I have to admit I've
never noticed this behavior before.

No need to take off :), just raise the gear with the engine running (otherways

Hi Syd,
As Oliver Thurau (ot-666) found out, many fuselage sections will decrease
framerates.
That's why it is better to have fuselage section only when necessary.

Adrian,
Great catch on the fuel and glideslope issues. You're right-- despite
parsing the fuel attributes and supplying defaults if necessary, it
has the defaults hard-coded right in the Airplane::compile block. It
seems to consider the user-supplied values for aircraft mass, but not
elsewhere. Ma
Just a note about the belly landing ... you can use fuselage objects
instead of fake gear each end of a 'fuselage' is a contact point
, and like the doc says you can have as many and in any orientation
you like ... though most people seem to be under the impression that
you can only model the
Hello,
I have found a couple of YASim issues, more details here:
https://code.google.com/p/flightgear-bugs/issues/detail?id=302
https://code.google.com/p/flightgear-bugs/issues/detail?id=303
Would anyone still maintaining YASim please have a look and provide
some feedback?
Cheers,
Adrian
