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.
Fuselage servo installation -
Install the servos in the servo mounting tray, following instructions
supplied with your radio control equipment. Connect the servo output horns and clevises and check
full and free movement – using the full range of the servo. Also check for any slop in the push-rods
and secure the Bowden cable carriers always keeping mind to minimise the length of unsupported
control linkage.
Note:
Depending on your choice of servos, you may find that you will have to remove a little material
in the area of the fuselage canopy opening to accommodate the servo output horns. Do so carefully,
removing only the minimum amount of material necessary to install and operate the servos.
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. 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). Be sure to roughen the surface of the
servo cover to ensure a good bond and use a countersink tool to recess the screw heads into the servo
covers. Ensure that the servo output arms are set at 90° with the servo electrically centred.
Tip:
Protect the servos with heat shrink sleeve. This makes for easy removal and replacement of the
servo, but care should be taken so as not to overheat the servos while applying the sleeve.
Receiver installation
- The receiver is best installed to the rear of the fuselage canopy opening, a
good quality Velcro Hook & Loop material is quite adequate for this purpose. The receiver antenna is
ideally inserted into a suitable antenna tube (or plastic Bowden cable carrier) and inserted down the
length of the fuselage.
The model is now largely complete, but some very important work remains to be done while still in
the workshop.
Balancing & Adjusting
In addition to accurate assembly, careful attention to balancing the model and adjusting the control
surfaces will serve to ensure a good flying model. The following data is provided in the interests of a
successful first test flight, we recommend that you follow these instructions initially, before further
adjusting the model to suit your own personal flying style.
Centre of Gravity (CoG) -
The CoG was first calculated theoretically and then tested in flight. Best
results were achieved with the CoG set at between 85 - 90 mm measured from the root leading edge of
the wing.
Longitudinal Dihedral -
Longitudinal Dihedral of 1° (equivalent to 1° up elevator) has proved to be
best and should ideally be measured with the aid of a suitable incidence meter.
