5. Next is the rounding for the DSA pipe ground. For one quality accuracy of fit becomes round
material With one requires a diameter of 14mm. Glue on it with double-sided duct tape
sandpaper. Then the gutter for the ground CFRP or plywood tube and the edge curve sanded.
6. Gluing the winglet and the wing transition.
Note: The winglets can also be used with easier V-position outwards, so not 90 ° to the wing.
Thereby however, the range increases. For a maximum applies to F3-RES competitions span (tip-
to-tip) of 2,000mm. The V-position should be a maximum of 75 ° so as not to negatively affect the
flight behavior influence.

7. The thin-walled 15mm CFRP tube is sanded and degreased (not necessary when running with
plywood round tube). Subsequently it gets into the gutter of the Wing transition and to the
glued winglet. On a good one bonding is to be observed! The CFRP or plywood tubes should
be 133 mm behind the nose edge of the rib 18 begin (see picture)!

8. Toothpick locking bolts and in rib # 18 stick together.
9. In conclusion, this will entire component finely sanded.
3.5 Completion
1. RC installation
When choosing the RC components - especially the servos and extension cords - necessarily on
lightweight components. These due to the geometry, parts are behind the focus. Heavy
components inevitably lead to the addition of lead in the tip of the trunk, which is the total
weight unnecessarily increased.
2. Covering
For the covering it will be easy material like the Oralight © transparent iron-on films
recommended. Everything should be done again before covering the exact fit and ease of
movement of the rudders and flaps are checked. One on a trial basis assembly of shell
construction is recommended. Attention, the outer three rib panels and the rib panels of the
winglets must in order to a collapse of the covering in the cold and to prevent bulging in heat,
with ever ventilated with a needle prick. It will not done, there will be negative ones effects on
flight characteristics
3. Attach the rowing and spoiler flaps. The flap hinges are made with Tesa executed. Then the
linkages completed will. On backlash-free pay attention to linkages.

4. Control of the set and the trailing edge using the templates or the wing slip. Eventual deviations
by careful fix twisting and re-ironing.
