How to set the end of a beam in Niagara

Hi I’m Creating a projectile of a piece of slime. I would like it to have a tail that goes out behind it. So I have created a projectile actor and I was trying to add a beam particle system that would go from the start point to the projectile.

However I cannot seem to get the trail to work correctly. I have create a beam and attached it to the projectile. I’m using a user.EndBeam for the end of the beam but it just is all over the place. I think the actor rotation is causing problems.

Does anyone know how to fix this?
