I love my Vamp Devil quad. I swore I would never fly a quad until I saw it. It is so much fun but not as precise as the REV. The long tail slows it down but draws a lot of attention. In lower winds, you take the tail off and keep flying.
I've been wanting to try the Mojo but my local kite shop hasn't been able to get one. Just about given up hope.
Sometimes I wonder if they aren't a little premature releasing new kites at KTAI when they aren't able to get them to the retailers.
