Note:
Don’t forget to make provision for adequate air-intake to cool the drive system. Some customers
may prefer to use a so called Turbo-Spinner which provides for intake of air through the spinner itself,
but make sure that adequate cooling is provided.
Only when the motor-mount is secure, install the motor (remember to use lock washers) and ensure
that the drive shaft turns feely and there is adequate clearances for the propeller yoke and spinner
assembly. For the sake of safety, don’t install the propeller until the model is complete!

Wings.
Despite close manufacturing tolerances very small deviations may be apparent in the wing seat and
fairing. While these may be corrected, minor deviations are of little or no consequence.
Joining the wing panels.
The openings in the two root ribs have been specially machined to accept the four supplied GRP
connecting tongues. Start by dry fitting the two sets of GRP connecting tongues in the openings in the
wing root ribs and ensure that they are pressed firmly into the recesses provided such that the
connecting tongues will overlap one another when the wings are joined. Once satisfied, bond the four
connecting tongues into place using a little thickened epoxy. Note: there is no need for excessive use
of epoxy as the openings are made in such a way as to prevent the tongues from being pulled out once
correctly installed in the wing roots.
Once the epoxy has cured, insert the Steel 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, carefully drill out the two holes in the overlapping connecting tongues
to accommodate the two wing bolts.
The wing joint is now complete.

Wing servo installation.
The TA Servo LOCK system supplied with your KULT Mini DUO provides a universal wing servo
mounting mechanism which is both simple and very secure.
Remove sufficient polystyrene to the inside the factory prepared servo-wells to accommodate your
chosen servos up to the inside of the upper wing skin. Reinforce the area of the upper wing skin with a
small piece of 100 g./dm ² glass cloth and epoxy resin. This prevents stress points in the upper wing
skin as a result of installing the servos.
The servo is simply bonded to the inside of the servo cover scoop and screwed onto the plywood
frames (see also the installation note supplied with the TA servo LOCK set). Note. Ensure that the
servo output arms are set at 90° with the servo electrically centred.
Aileron control horns.
ARF customers - remove the covering in the area of the aileron control horns before proceeding.
