RE-J10 "Wolfhound" Engine - Node Alignment

[klesh]

This is fixed in 1.4.2, though the thrust is still offcenter.

 

Hi,

It would appear that the RE-J10 "Wolfhound" engine is out of alignment:   

The above is the SM-25 Service Module with the RE-J10 "Wolfhound" placed under it.

Yep. If you use the rotate gizmo and spin it about its main axis the alignment problem is really apparent. Lots of wobble. No idea if the thrust is offset too; I would guess probably.

Yes, RCS Build Aid (functioning in 1.4.1 as far as I can tell) shows offset thrust.  I'll play with adjusting the node mount points... I've been poking in the cfg's but it's not obvious what to adjust, as there are seven numerical arguments to the node attach module.  What are they? 

EDIT: the Cheetah LV-T91 also has off-center thrust, though its model seems to be centered.

Any hint when and if this ever gets fixed ?

I will add that the new Rockomax Jumbo-64 tank (the re-redo, with the pipes back on the side) is also offset from center:

When you adjust the Wolfhound or Cheetah to center their thrust, then their mass is off-center, which means the rocket will still tumble. It makes both these engines basically unusable

Its strange.  Despite the off-centering I haven't experienced any actual in-flight issues with either the Wolfhound or Cheetah engines.  All flights with them have been nominal.

The offset is small, so thrust vectoring and SAS keep it from becoming a problem.

Indeed, I had read elsewhere that the peeps having tumbling problems with it were not using SAS at the time of their burns.  If SAS is on my ship, I'm using it!
