Another plane can possibly do roto-landing is Morris Spinsation. It's flat spin is comparable to Endoro if not better. It spins very flat (nose slightly up) and decends really slow with a OS FX46/mousse can muffler. I never do roto-landing on this plane because it is too much fun to fly. It does a lot more cool tricks in the air than roto-landing, so I'd rather keep it float. But I have no trouble to flat spin it down to 5 feet high and recover.
