Seems there is one reason to use them, that have been the driving force behind using them on full-scale and models that has not been mentioned here: They are out of harms way if landed off regular landing areas, where tall, sturdy, grass and low bushes can easily rip off a low set stabilsator. Seen it happen more than once with models, and on full-scale it is usually restricted to wear and tear. Also less risk for damage in the hangar, and so on. True cruxiform tails might be the ticket? Where the stabilisator is low set but the bottom half of the fin projects quite a bit downward. lifting the stabilisator from harms way, and the nose digs in better, too! Probably the lightest way, too, as the twisting loads on the tail boom is decreased! Tord RCSE-List facilities provided by Model Airplane News.
