Rotate two objects at opposite angles at the same time?

[CyanPrime]

Hi, so I'm trying to figure out a way to rotate two objects at the same time. These are top down wings I want to go back and forward. When I try doing them one at a time the angles are always slightly off, so I'm hoping theres a way to grab two objects, and rotate them inward and /or outward at the same time (one going clockwise, and one counter).

Is this possible, and if so -  how?

Thank you for your time.

There's no way to do this... but why would they be slightly off?  If you have them both rotating the same amount and use the same key-frames for their beginning and end positions, they should be perfectly synchronized.

You can also do some math to make sure they both are rotated the same number of degrees between each key frame as each other.

Can you explain in more detail what the problem you're facing is?

 

Thanks.
