ARC customers – complete this step once the wings have been covered.
Carefully mark the position of the aileron horns with respect to the output arms of the two aileron
servos. Drill a Ø 4 mm hole into the underside of the aileron at the positions marked, taking great care
not to pierce the upper skin. Check the supplied metal horns (eye-bolts) for proper alignment with
respect to the aileron. Remove a little extra material inside the hole and fill with a suitably thickened
epoxy resin before finally bonding the eye-bots in place. A small bead of epoxy around the diameter of
the eye-bolt is a good indication of a secure installation.
Note:
More experienced aero-modellers may wish to install alternative control horns of their own
choosing, but please ensure that they are fit for purpose and properly installed.

Wing servo connections.
Prepare suitable cable harness and connectors to connect the two wing servos to the receiver. The
cable harness should be made long enough such that the connectors are located just below the wing
seat. Suitably polarised high-current connectors should be used to avoid misconnection. Twisted servo
leads; with a wire diameter of no less than 0.25 mm ² is recommended.
Note
: Quality cable sets, including connectors and separation filters are available via the specialist
trade; choose high quality components for optimum reliability.
The basic airframe is now complete!
ARF customers – should now move to installation of the radio control equipment.
ARC customers – should now begin the finishing stage.
Finishing.
Film covering –
all the wooden surfaces are supplied pre-sanded, but will benefit from further fine
finishing prior to covering. Follow the instructions provided with the covering materials, always
taking care to make all joins in the direction of the air-flow.
As an alternative to our own high stable decorative vinyl based covering material, we can also
recommend Oracover (Profilm) covering materials.
NOTE
: Take care to avoid excessive heat when using heat-shrink covering films on the wings as the
polystyrene cores will be destroyed (polystyrene starts to melt at 70°C). Use low temperature heat-
shrink covering films and make every effort to avoid prolonged exposure to heat.
Fibre-glass finish
– for the ultimate finish to your KULT Mini DUO, cover the wings and V-Tail with
a lightweight glass-fibre cloth and treat with a suitable finishing resin. This involves a specialist
process which is well documented in the popular hobby press. Choose good quality materials and
follow the manufacturer’s instructions. Take care not to add excessive weight!
