Melchior,
This stuff can get confusing, and I hate to reopen a big can of worms,
and I didn't really pay attention to the JSBsim VRP discussion a while back.
With YAsim you can pick any point as the (0,0,0) point and reference all
your dimensions and positions from there. YAsim handles this

Curt quipped:
If you want to use the same 3d model for multiple FDM configurations
which choose different reference points, then that makes life a lot
harder. I think that is what the JSBsim VRP is for.
I had to laugh when reading these two sentences together. It sort of read ( to me )

I know. But still, YASim's origin (the nose) is the (unchangeable) VRP, or what
JSBSim calls VRP, right? And the 3D model would also have to be moved such
that the nose is at YASim's 0/0/0, too. But the bo105 does only turn around the
CG if the main *rotor axis* wrongly

Where you might be getting confused is with the view system. If (0,0,0)
is the nose, then all the external views will center around the nose.

You wrote pretty much the same as Jim, but you obviously

Well, I don't know. I've just flown it using a recent CVS
download. It
looked really good to me.
Melchior FRANZ said:
Did you put the target offset in the right place, in the right file?
I think so, yes. (Well, I hope so, at least. :-)
Can you post what you have, with the model fixed and the target-offsets in, etc?
Best,
Jim

Yes, see what you mean, but I think we went through all this with

I think all views are fine, although view 2 is a bit disconcerting or even a
bit disorientating. This seems to be a view-based issue. I'm convinced that
the aircraft is rotating appoximately around it's cofg.
