I only have RF 6.5, but have already played on the Drone version at the local hobby shop. It's actually pretty sweet. Plus it has the Heli-Max Voltage 500 3D.
Sorry your experience with RF 7.5 wasn't an awesome experience. Being software, once you open the package and register it to fly, you own it. So no return. But hey, if you are truly unsatisfied, eBay it.
Thought you might have taken my advise and bought the Drone package. Oh well, lessons for others who may happen upon this thread and take my forewarned heed. ;-)
I did that survey three days ago...
