Its designed by Wolfgang Zach, the winner of CONTEST Euro-Tour 2000, and build by Markus Podivin. Nice shape, easy throwing, top performance. Height gained from 30 (calm) to 40 meters (windy), throwing speed up to 100 kph, flight time in calm air mostly more than  90 seconds. Fortunately Wolfgang and Markus sell their "Fireworks", you will get the carbon boom, the carbon wing saddle, a carbon nose and the wings. The control surfaces have to built of a light 5 mm balsa by oneself.

The receiver Graupner XN-12 was replaced by a JETI5 because of some interference. Friends nearly lost their Fireworks with the same  configuration (Futaba FF8 Transmitter), so I decided to change it too.

Flying
Flying with such a modern hlg is a joy. Its flying behavior is excellent, because of the snapflap function it circles very narrow and slow without any stalling tendency. Flaperons providing direct and fast reactions also in turbulence. At start with SAL no trim is needed and the height reachable makes my bungee worthless. Just perfect ;-)
To have optimal contact I use a right hand glove for golf. It is thin and has some rubber on it.
