How do I do a simple rotation?

Basically, I'm wanting to have an object floating/hovering above the ground, and would like it to spin round gently until I tell it to stop. Can anyone suggest, please, which function(s) are best for this, and whether it should be a physics or non-pphysics object? My objects either just rotate a bit tand then stop, or whirl and zoom of, or do nothing....

I think that llTargetOmega will be your friend here:

with physics on there are some weird effects with prim rotation... has something to do with the mass of the object i think...

try it... its funny
