Rotate object with rigidbody and high angular drag around particular local axis

I want to rotate a rigidbody around its local x axis.

I've already tried it by adding torque but the problem is that the angular drag has to be very high so it's not possible to just add torque on the x axis and that's why I have to set the angular drag down on the x axis. But angular drag is of type float so that's not possible. I've also tried to recalculate the angular velocity but the result was just strange.

My second idea was to rotate it by repositioning the center of mass but that didn't work either because the rigidbody doesn't calculate a new position when the object is in the air.

If someone has an idea how I could recalculate the angular velocity to get a result that looks right or how I get the rigidbody to also calculate in the air, it would be great.

I'm also open minded to completely new ideas.
