Once the epoxy has cured, insert the wing joiner and check that the four connecting tongues
overlap. You may need to file a little material away on one or both edges to achieve a snug
fit.
With the wings joined together, check that there is no gap between the wing halves and
carefully drill out the two holes in the overlapping connecting tongues - to accommodate the
two wing bolts.
The openings for the servo cables in the wing root ribs are also pre-fabricated.
The use of high current (green) plugs and sockets are recommended here as these are
polarised and facilitate simplified assembly at the flying site.
The wing mounting nuts have consciously not been pre-installed in order to accommodate
inevitable tolerances in the manufacturing process.
With both the wing seat and the wing joint complete, as described above, align the wing on
the fuselage and carefully check the position with respect to the tail. Next temporarily secure
the wing in place with adhesive tape and then, with everything still carefully aligned, drill
6mm pilot holes through the wing joint into the fuselage wing seat.
Now, remove the wing assembly and open out the fixing holes to a diameter of 7.5mm – to
accommodate the blind nuts which are inserted from the inside the fuselage and bonded into
place with suitably thickened epoxy resin.
Tip: Use clamps to hold the blind nuts firmly in place such that the top of each nut is
flush with the surface of the fuselage wing seat - until the epoxy has thoroughly
cured.
The TA Servo LOCK system supplied with your KULT Champ kit provides a universal wing
servo mounting mechanism which is both simple and very secure.
Remove just sufficient Styrofoam from the inside the factory prepared servo-wells to
accommodate your chosen servos up to the inside of the upper wing skin. If you do remove
all the Styrofoam from within the servo well we would recommend that you apply a small
piece of 100 gr./m² glass cloth, suitably wetted with epoxy resin - to protect the wing skins.
Note: In the case of the ARF version, the plywood servo frames are pre-installed at
the factory.
Screw the servo covers onto the plywood frame and mark the centre of the scoops.
Carefully mark and extend the centre line of the exit fairing of each servo cover to the
corresponding control surface – in preparation for installation of the control horns.
