other ways to launch your sky diver???

I have a a couple of 2.5 lb rc sky divers, but I dont get to use them much because I need someone else to fly the drop plane...

I have tried largeair powered"spud gun". not enough power...
I have tried bungiee on goal post at local school.... to hard to set up.

any ideas??
