Procedure depending on the version
Depending on whether you want to build the free-flight version
or the RC version, the approach is different. If the model is
assembled as free-flight version, it cannot be converted to RC
version. Therefore pay attention to the related assembly steps
sequence. (see diagram)
Note
To build the RC version you need the RC conversion kit No.
4616.90 (not included in the kit).

Required tools and facilities (not included)
Assembly steps 1 to 17 for free-flight and RC version
Glue the angle ledge (36) to the wing edge (34)
Note:
Note that a left and a right half-wing are included. In order to let
the wing panels have approximately the same weight, join the
balsa components accordingly. Pair the heavier wing ledge (34)
or (35) with the lighter parts (36) and (37). Immediately remove
the excessing glue.

Glue the rear edge of the wing (37) to the angle ledge (36)
Note:
Due to the water content in the UHU glue, the wing edge (37)
may become curved in the gluing area. To avoid it, lightly moisten
the wing edge gluing area from the top with a kitchen sponge.
Immediately remove the excessing glue.
Profile the wing edge (34) with the sanding block
Note:
Remove the black marked parts from step B-B with the sanding
block. Profile both left and right wing-halves accordingly.

Glue the balsa junction part (38) to the profiled wing
Refine the upper side of the balsa junction part (38)
Note:
Refine the balsa junction parts with the balsa cutter first.
CAUTION
INJURY RISK, MOVE THE CUTTER ALWAYS IN THE OPPOSITE DIREC-
TION OF YOUR FINGERS AND HANDS.
Then sand it parallel to the upper wing side using the sanding
block. Therefore the junction part will automatically get the
curved outline.
