The video really does not do the plane justice. I have been an observer of this plane being flown.

The plane gives you confidence just watching it. In a slight headwind it drops vertically with the ailerons up and elevator applied. You might saty no big deal, but it also stays rock solid and does not advance. Only my fun-fly machines with monter crow would do that!. No dutch rolling or heading deviations. It continually tempts you to land it at the bottom of the Harrier. I suspect that many of you will over-do this maneuver.

The hover is simply less work. Much like teh DV it has a liking to being pointed up. Flat spins are fun to watch. It will do much more but I don't want to give Tumbler all of my secrets :-) (VBG)
