The linkage shown is done with a Dymond D47 servo. Here the servo arm with a 3x1 CFRP profile
or one appropriate GRP or plywood cutout can be extended. The servo arm length must be
individually adapted to the used servo can be adjusted and should be about 25mm. The cutout in the
spoiler base plate must also be customized.
1. Extend the servo arm.
Roughen the adhesive surfaces well degrease. Reinforcement with CFRP winding.

3.4 Winglet with DSA tub
e
The winglets are built in the classic balsa rod construction. At the winglet foot comes a so-called
DSA pipe is used. DSA means pressure-suction discharge and improved the flow conditions at the
wing-winglet transition. This has essential Effects on the very good-natured behavior and the
controllability in slow flight.
1. The individual balsa parts for the winglet are prepared and as a test composed. The individual
diagonal struts are marked with small holes, please refer image. Fix the parts on the building
board and stick together.
2. Then the winglet can roughly be sanded
3. Construction of wing winglet transition. The parts you need are on the image visible. You're
with me again marked small holes

4. Be into the # 18 plywood rib two toothpicks stuck and the Balsa parts threaded according to the
pictures and glued. This phase of construction should be done beforehand be played through
dry once, this ensures that nothing glued together incorrectly.
