  fireworXtend
2m-DLG
Unique super soarer for SAL-launching
     

 
Model:
fireworXtend
Wingspan [mm]:
2 000
Weight [g]:
ca. 420
Airfoil:
AG455ct-02f - AG47ct-02f

Our well-established model Fireworks has been "eXTENDed", that is enlarged in all dimensions. The model that resulted, "FireworX Xtend = fireworXtend", is the only 2m-DLG on the market at the moment.

Xtend offers maximum soaring fun with minimum effort. It starts with SAL-launch in any weather. Thanks to its gliding characteristic Xtend reaches up-draughts, of which we were only dreaming before!

For more technical information have a look at our Building instruction FW-X-tend (pdf-file)


Details:
The construction follows those of Fireworks4. The wing is produced with a shell of glass and balsa-sandwich with a grid of carbon rovings (disser) inside the shell.
The concept for the fuslege is also taken from Fireworks4. Cone and boom were lengthened, the front part with servoboard and canopy to slide on was kept.
The servos for vertical and horizontal stab are situated inside the fuselage. The servos for the ailerons are fitted inside the wing.
The two-part wing is fixed on the fuselage with 4 screws.
As well as Fireworks4.2 fireworXtend has fences between flaps and fuselage for an optimal aerodynamic transition.
The rudder was enlarged for optimum launches.
In series production carbon fleece is also used on the outside of the shell of elevator and rudder.
Carbon inlays serve as additional strengthening for the installation of the stab on the boom.
You can easily demount the elevator for easy transport. The wing is divided into 2 halves.
