I have the original Typhoon that I've been flying for 16 months and I absolutely love it. My only complaint is that the plane flies so well upside down, that its very easy to loose orientation if it gets a little too far away from you. During the first three months, i crashed the plane three times because I lost orientation. I finally painted it two distinctly different colors: blue on the bottom of the fuselage and wings, red on the top. Haven't lost orientation since then. It slows down very well for landings and is capable of all types of aerobatics, including hover, knife edge, etc.
The MUS is a great flying plane. There are six flyers at my field who have it and they all absolutely love it. I bought a used one but have not assemblesd or flown it yet because I just hate the way that this plane looks, but it is a terrific flyer.
