I'm no engineer and last time I studied physics was high school.....but the biggest red flag that comes to me when you said no external torque is that the momentum is conserved.
The classical explaination of what that means is with figure skaters.
When arms are extended, they are spinning at a given rate.
But if they pull the arms in, thus shrinking the spinning radius, they speed up relative to the original speed.
If they extend arms out, they revert back to original speed again.
