Make an entity wobble

So I need to make my SENT Wobble back and forth (on the Roll axis) and I can’t seem to come up with a good way to do it.
I’ve tried using constraint.Keepupright on it with a decent threshold and poking at it with AddAngleVelocity
I’ve tried using a ShadowController to keep it upright (with the target angle) and some dampening as well as AddAngleVelocity
I’ve tried setting its angles through a Sine function

None of these seem to really work. They either don’t have enough of an effect, have to large of an effect or aren’t “flickery” enough - too slow.

At this point I think setting its angles through a Sine function would be the best but I can’t seem to get the equation right. Anyone have any ideas?
