Hi BigFoot!
No, no , no, I’m not angry at all. Thank you for letting me know where to put scripting-related-questions properly.
In my project, I let the movement to control the model directly and surely I face lots of issues and you mentioned some of them right-on. Now I can see why it has more ADVANTAGES of attaching a model to a node. 
Now, it’s time for a re-write!
Thank you for your assistance
Kind Regards,
