brand-new) balsa knife blade. Now remove the canopy and rud-
der, and use a small pair of nail-scissors to trim away any excess
decal material along the cut edges. If you prefer, you can fold the
decal round the rudder leading edge and into the hinge line gap.
13. Final assembly, balancing the model (KIT + RR)
Slide the wing joiner tube 59 into one wing panel, then slip the joiner
through the fuselage. Route the aileron servo lead up and out of
the way before sliding the second wing onto the joiner tube. Fit
the wing retainer 71 to prevent the wings slipping out of position:
simply push the unit through the wings from above and into the
M-frame. Now install your receiver; we recommend attaching it to
either fuselage side with hook-and-loop tape close to the battery
plate latch position. Connect all the servo leads to the receiver in
the appropriate sequence.
Place a flight battery on the battery plate 70, and adjust its position
until the model balances at the correct point. With the canopy fitted
on the fuselage, the Centre of Gravity should be 100 mm aft of
the wing root leading edge.
14. Control surface travels
Set up the control surface travels as stated below. They are only
a guide, and you may wish to alter them to suit your personal
preference:
Normal aerobatics ("pattern" flying), outer holes at the control
surface horns:
Elevator:

Ailerons:

Rudder:

3D aerobatics, middle holes at the control surface horns:

Dangerous, and for the true professional only:
! CAUTION !; in this configuration the model is extremely respon-
sive. The airframe has been tested successfully at loads of up to
18g. To achieve these control surface travels it is necessary to
modify the aileron and elevator horns as follows: cut away the
brace below the swivel pushrod connector 83 using a small pair of
pincers or a mini cutting disc, and connect the swivel connectors
to the control surface horns as far inboard as possible.

5% opposite aileron to rudder;
i.e.: when rudder is at full right, the ailerons deflect 5% to the left;
when rudder is at full left, the ailerons deflect 5% to the right.
5% elevator to rudder;
i.e.: when rudder is at full right, the elevator deflects 5% up; when
rudder is at full left, the elevator deflects 5% up.
15. Safety
Safety is the First Commandment when flying any model aircraft.
Third party insurance is mandatory. If you join a model club,
suitable cover will usually be available through the organisation.
It is your personal responsibility to ensure that your insurance is
adequate (i.e. that its cover includes powered model aircraft). Make
it your job to keep your models and your radio control system in
perfect order at all times. Check and observe the correct charging
procedure for the batteries you are using. Make use of all sensible
safety systems and precautions which are advised for your system.
An excellent source of practical accessories is the MULTIPLEX
main catalogue or our website www.multiplex.de
MULTIPLEX products are designed and manufactured exclusi-
vely by active modellers for practising modellers. Always fly with
a responsible attitude. You may think that flying low over other
people's heads is proof of your piloting skill; others know better.
The real expert does not need to prove himself in such childish
ways. Let other pilots know that this is what you think too, as it is in
all our interests. Always fly in such a way that you do not endanger
yourself or others. Bear in mind that even the best RC system in
the world is subject to outside interference. No matter how many
years of accident-free flying you have under your belt, you have
no idea what will happen in the next minute.
Before every flight, check that the battery, the wings and the
tailplane are attached and firmly seated. Check in turn that
each control surface is operating correctly!
We - the MULTIPLEX team - hope you have many hours of ple-
asure building and flying your new model.
