Went through the material, spot on, I did end up saving a bunch of time by just using the original Pitch constraints and selecting corresponding flaps and objects and using the Copy to Selected so I didn't have to recreate each one. Just make sure the rotation is accurate to the one you're copying to!
With Blender 4.0, I did have to do some playing around to figure out the updated constraint system, but stick with it and you'll figure it out by the end! Just proves to show, you can definitely use this as a guide for the most recent Blender version. Great work really enjoyed it.
