When I do the constraint in mine I have to make sure the Plain axis empty is on the same Z location as the rotor blades otherwise it throws the blade at a weird angle. Any Idea why it isn’t acting the same as in your video? I’ve tried it on different versions (7.6.5 and 7.3) and it acts the same way.

That sounds correct to me. Axis orientation is very important for constraints, parenting, and rigging in general.

Thanks for the reply Kent. In your video the plain axis empty is above the rotor blade. When I tried it yesterday the plain axis empty had to be the same level as the rotor blade. I tried it again today and it worked like in your video with the plain axis empty above the blade. I’m not sure why I can’t get consistent results. I’m sure it’s something I’m doing that’s causing the inconsistent results. It’s all part of figuring out Blender.

I got it to work. I didn’t see anywhere to publish a video so I put it on Youtube. Hope that’s OK https://youtu.be/L0MBufWIa8A
