Merge request landed: https://sourceforge.net/p/fgspaceshuttledev/code/merge-requests/31/
The branch on which it is developed is this one (adjustrms):

I'll post more information, but:
1) I did not change the way payloads are rolled once attached onto the RMS. It is not a solid motion as it should in SINGLE mode, but it is the clever way to do it to not have Euler singularity effects [If this is voluntary, well done Thorsten ]
2) I did change the way the camera roll though, it should solidly follow the end effector, but not necessarily the payload then.
@Wayne, that should fix your moving frame! BUT, Euler singularity cannot be removed, so if you see shifts appearing at high pitch, we're done. These won't be fixable with the jsbsim channels we have now. Let me know how it goes! (I think we could add some ALS filter onto the view instead, in case the 3D frame is not good enough).
Edit with more info:
I've added a grapple fixture on all payloads. With the RMS tuning, the ac3d files of any payload have now the origin located on top of the head of the grapple fixture pin, this ensures good centering and offsets matching the end effector kissing the grapple fixture once the payload is grappled (so no more tweaking of this origin to align the end effector and the fixture).
I have also changed the diameter of the end effector to match 38cm (as reported in another posts), and all grapple fixture should be accurately sized (22.5 inches diameter). This is important for the camera to be just in front of the grapple target. Moreover, the camera is now on the wrist-roll, which is closer to what I can see on some RMS pictures. Plus, being exactly on wrist-roll location helps to minimize some errors in the computations of its coordinates.
In case someone wants to add a new payload, I have put the grapple fixture blender files there:
grapple_fixture/
Being already correctly sized and positioned, just add the payload around!
Let me know if clarifications are needed.
Cheers,
Chris.
PS: check how Spartan is not translucent any more
