A plane can be quite tail heavy before it becomes non-flyable. It also can be very nose heavy and still land decently with full up elevator.

That is sorta true...buttail heavyairplanes with too muchelevator throw can and most likely will end up in a very bad landing, most often a crash. I just flew my aircraft again this afternoon. I put it into inverted flight and let the stick go to center. The airplane just barely dove....that is the way I like it. I can also fly it hands off and it goes strait & true. The landings are super fun....I love it! Capt,n PS Tom, I am ready for a bigger one already!
