Constant Rotation

HI everyone.

I need to get the rotors of my helicopter model to continuously rotate. I’ve found multiple tutorials and kind of understand what i need to do.

One way of doing it seems to be using a cycle modifier like the video at the link.

But for the life of my I can’t seem to find the modifiers panel. Pressing N to get the fly out menu on any of the animation panels just either shows a blank panel or cursor select panel.

I am using 2.91. I must be missing something really obvious… :D… Its driving me nuts! Thanks for your help.

you need to select the track you want to give the modifier to, like Z Rotation for example:

Thanks very much… :smiley:
