Magni makes a great product, albeit very expensive.
I was disappointed to see American Gyrocopter (Groen Brothers) go out of business, as theirs were very good products, and they offered good training and support.
There does come a point of diminishing returns, however, when the simplicity and grace of the gyro can be overwhelmed by excessive cost.
The experimental world goes that way, too; homebuilding airplanes can be economical, but the whole business of homebuilding airplanes has lead to some that are far from affordable (though there are many great designs out there, and some with very exciting performance, too). I suppose it depends on your resources and what you're after, and I'm certainly not maligning Magni or any other manufacturer. There's no doubt that you get a great product in exchange for your hard earn pounds, dollars, euros, or whatever. Whether the cost of the exchange is worth it or not is entirely up to the user, but I think the simplicity of the gyro does take a bend away from it's true appeal when it begins to becomle too costly and complex.
Nice video.
