Joint can't rotate

Hey guys!

I’m messing around with the physic/rigidbody system in unity to see if it’s good enough for my project and I have a problem. I’m using joints to group my objects together, but I can’t rotate them. I tried with code and even in the scene, but it only shakes for a frame and then resets.

I have a weight attached to a “rope” attached to a sphere that is suppose to rotate with code. I want everything to keep their original forms(not bend like an actual rope would do).

Hope you can help me!!

Kinda found a turn around, if I added a ton of mass and set drag and angular drag to infinity, I can rotate it, but is stills rotates towards the ground. Anyway I can do it without multiplying the mass by 500 and keep it still.
