Finishing
Attention! Your new KULT Champ is built using very sophisticated LTSCP (Load
Specific Covering Thickness Procedure) for superb flying characteristics, but this also
has the effect of considerably enhancing the thermal conductivity and as such
particular care must be taken to avoid excessive heat when using heat-shrink covering
films on the wings and tail-plane. Use low temperature heat-shrink covering films and
make every effort to avoid prolonged exposure to heat as the Polystyrene cores can
be destroyed if exposed to excessive heat. Polystyrene starts to melt at 70°C!
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. When covering the control surfaces
with integrated Elastik Flaps (elastic hinges), take care to apply the film with the moving
surfaces fully deflected so as not to restrict the movement
Fibre-glass finish
– for the ultimate finish, cover the wings and tail-plane 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 model trade. Choose good quality materials and
follow the manufacturer’s instructions. Take care not to add excessive weight!
DESIGN Models.
Our DESIGN range of models are supplied with pre-printed graphics which are both
lightweight and durable. Please observe the following simple steps to maintain the
appearance:
•
TA-Film is stable up to a nominal temperature of 70
0
C so care should be taken not to
expose the surfaces to excess heat. The use of a normal hairdryer is all that is
required to soften the material should it eventually become necessary.
•
The graphics are waterproof but are not resistant to solvents. Clean your model with
a mild solution of soapy water applied with a soft sponge and dry carefully to restore
the fine finish.
•
Do not under any circumstances use cleaning products which contain concentrated
alcohol or acetone as a solvent.
Radio Control Equipment Installation.
The precise positioning of the components installed in the nose of the fuselage will depend to
some degree on your choice of receiver battery. Check the physical layout of the
components, bearing in mind the recommended centre of gravity point.
Fuselage servo installation
Install the fuselage mounted servos in the cut-outs in the servo mounting frame according to
the instructions supplied with the servos. Attach the linkages so as to use the maximum
available throw, i.e. use the inner-most holes at the servo arm and the out-most holes at the
control horn! Always ensure that all the linkages are secure, there is no binding and are slop-
free.
