The airfoil is from Max Steidle (Wing: M
1580 and M1585, other: M08), who also made airfoils for
models such as the Crossfire or Tool. He deserves
acknowledgments.
The Evolution is the first serial produced model with no
control horns on the outside
To reach the maximal precision in the prototype production,
a 3D mill cutter was used. The programs were made with the
help of our webmaster, Michal Michna.
The wing of the model has a slight V form. The surfaces
are moved using a torsion control.
Ballast is placed in the wings. The standard version is a
wing sandwich made of carbon fibre, Rohacel and glass
fibre. The spar of the wing is made of UMS carbon.
The fuselage, mostly of carbon has an improved system of
elevator control and a reinforced rudder construction. The
diameter is kept to a minimum.

instruction...

-
To form the cogwheel of the servo into the aluminium use a good liquid
mould-release. You can use slightly thickened Epoxy for this.
-
You have two different bended
steel. The more bended (55 deg.) is for flap and the other one (40
deg) for aileron.
-
First you have to fix the servo-mount in the wing. Make a drawing on the
wing like shown on the picture and glue the servo mount in the right
position.
-
Next step is to glue the brass-tube into the bar.
-
Last step is to glue the bended steel into the aluminium. To gauge it on
the right place you take a long time-epoxy and mount it in the
wing. Then
you must move the flap up and down two or three times and the steel will
gauge automaticly. Fix the flap in a neutral position and wait 12
hours.
Make sure that the little screw on the aluminium is on the upper side !!!!
-
After all use a teflon-grease on the steel and the slot. This helps to
minimize abrasion and radial clearance in the future.
