Nothing yet; it's sitting in the box on a shelf, like so many others right now I'm really in a quandary about what to build next. Obviously the UPF is high on the list. Help me out; what would you do next given these choices. Consider that the engines are available, all that would be needed for any one are Rx and servos.
