ok, so I fixed the issue and I'm not even sure why it worked. I started with a blank scene, deleted the old jetpack prop from my library, and then imported the retracted wing .obj. When I did, one of the import options was "place on floor". It wasn't checked, but it had never been checked before either. In this case, I clicked the check box just to see what would happen, and proceeded to import. Then I loaded the morph target (extended wing .obj). I turned the newly created erc dial and it behaved exactly as I wanted it to..... it sat perfectly still as the wings extended and retracted. So it worked. Wow... not even sure why, but I'm glad it did
