Is it possible to add a helipad to the top of a buidling in NYC? I have Aerosoft's Manhattan scenery, and I'm not sure if it would work, but it's worth a try.
This program Rwy12 Object Placer should be able to do what you want. Once you figure it out it'll work fine.

Thanks radarman. I'll let you know if it works out.
