7.3 Protective landing skid (pic. 22&23):
To protect the model when belly-landing on grass, we
recommend fi tting the protective landing skid # 22 4329.
This is simply fastened to the underside of the model,
and secured with a little adhesive tape or double-sided
tape at the rear.
8. Preparing for the fi rst fl ight
Wait for a day with as little breeze as possible for the fi rst
fl ight. The evening hours often provide the best conditions.
Be sure to carry out a range check before the fi rst
fl ight!
The transmitter battery and fl ight pack must be fully
charged according to the instructions.
Set the transmitter to range-check mode, and ask your
assistant to walk away from the model, carrying the
transmitter.
As he walks away your friend should constantly operate
one control function while you watch the model’s servos.
The servo not being operated should stay motionless up
to a range of around 60 m, and the other servo should
follow the transmitter stick movements smoothly and im-
mediately. If successful, repeat the check with the motor
running. The effective range should not be signifi cantly
reduced when the motor is running.
If you are not sure about anything, do not fl y the model!
If you cannot eliminate the problem send the whole radio
control system (including battery, switch harness, servos)
to the manufacturer’s service department for checking.
The fi rst fl ight ....
Do not test-glide this model!
The model is designed for hand-launching - always exactly
into the wind.
We recommend that you ask an experienced modeller
to help you during the fi rst fl ight.
Allow the model to climb to a safe altitude, then adjust
the trims on the transmitter so that the model fl ies straight
ahead without any help from you.
At a safe height switch off the motor and make yourself
familiar with the model’s control response on the glide.
Carry out a dummy landing approach at a good height,
so that you will feel confi dent about the real landing when
the fl ight pack is fl at.
Don’t attempt tightly banked turns close to the ground at
fi rst, and especially not on the landing approach.
It is always better to land safely some distance away, and
have to walk to collect the model, than to risk damaging
it by dragging it close to your feet.
9. Safety
Safety is the First Commandment when fl ying any model
aircraft. Third party insurance should be considered a
basic essential. 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 ad-
equate (i.e. that its cover includes powered model aircraft).
Make it your job to keep your models and your radio con-
trol system in perfect order at all times. Check the correct
charging procedure for the rechargeable batteries used
in your RC set. Make use of all sensible safety systems
and precautions which are advised for your system. An
excellent source of practical accessories is the MULTI-
PLEX main catalogue, as our products are designed and
manufactured exclusively by practising modellers for other
practising modellers.
Always fl y with a responsible attitude. You may think that
fl ying 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. It is in all our interests
that you let other pilots know that this is also what you
think. Always fl y 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 fl ying you have
under your belt, you have no idea what will happen in
the next minute. We - the MULTIPLEX team - hope you
have many hours of pleasure building and fl ying your
new model.
