That would require to know the exact scale settings of the particles and their position values as well as their settings in the E3D editor. Looks like a simple scale issue to me due to to pivot point placement being off. I don't have the Jet Pack and only Metropolitan, so I can't check. Perhaps you can ask on the VC forums...
Well , i missed with the jet scale to fit on the roof and the anchor point because it was very big to be in that position
I try to reset some of setting may be you are right .

Hey Aloooy, I think I understand the solution to the issue you are having.
It looks like you are you using more than one layer of element.
Your Jet is on an Element layer above the buildings layer and positioning the two can be difficult in Version 1.6
When Element Version 2 is released, you'll have the ability to add several objects to the same group and accurately position them in the Element 2 viewport.
