For more technical information have a look at the Building instruction (pdf-file, 3,7MB)
For more details of the model read the review of Aufwind-magazine (German).

SUCCESS IN COMPETITIONS 2007:
David Kauran takes 3rd place with Fireworks in the Euro-Tour (victories in Celje, Ludbreg and Zapresic, second places in Waidhofen and Reiselfingen) and is winner of the Austrian Cup.

available in 4 versions:
Kit with
carbon wing
from 300g
highest stiffness
Kit with
disser wing
from 275g
für allround use
Kit with
glass wing
from 265g
light Version

Kit with
glass wing
from 230g
ultra-light Version
(elevator / aileron)

Fireworks III now as ultralight with 230g flying weight!
Even if your launch is not very strong, you will start this glider to good heights for thermal flight. Due to the low descend, Fireworks III ultralight is the perfect glider for weak conditions and windless days.
In order to minimize weight, we used 19g glass to build the wing. The weight of the wing could be reduced to app. 100g. more pictures

The balsa stab was taken from FW4.2 in a revised version. FWIII ultra has no rudder in order to save weight.

These stabs are now also enclosed in all other kit versions of Fireworks III (with rudder).
