How to create vapor trail from wing edge?

I’m not sure what kind of alignment issue you are having but they shouldnt be spinning freely if you use Spawn Per Unit module. They will spawn as the object they are attached to moves and keep their spawn location. I had done the same thing in this video after 1.25: Supersonic Zeppelin - UE4 - YouTube
