Is it possible to add a Motor6D to a custom model?

Hi,

From a long time I have been trying to script a motor6D to my model, but apparently none of my tries worked and they had to be erased. I want to ask if you could Help me improve my script (Wich is the only thing I could save).

Weld.Part0 = HumanoidRootpart

Weld.Part1 = Head

Weld.Part1 = Torso

Weld.part1 = Right arm

Weld.Part1 = Left arm

Weld.part1 = Right leg

Weld.part1 = Left leg

Thank you for attention.
