Installation notes
Your receiving system must be installed correctly in
the model. The following are a few suggestions when
using
GRAUPNER equipment:
1. Wrap the receiver in (anti-static) foam rubber at
least 6 mm thick. Fix the foam round the recei-
ver using rubber bands to protect it from vibration,
hard landings and crash damage.
2. The receiver aerial must be secured in the model,
so that there is no chance of it becoming tangled
in the propeller or control surfaces. However, it is
best not to deploy the aerial in an exactly straight
line, but to angle it: e.g. run it straight to the tailpla-
ne, then leave the fi nal 10 - 15 cm trailing freely,
as this avoids reception “blind spots” when the mo-
del is in the air. If this is not possible, we recom-
mend that you lay out part of the aerial wire in an
S-shape inside the model, as close to the receiver
as possible.
3. All switches must be installed in a position where
they will not be affected by exhaust gases or vibra-
tion. The switch toggle must be free to move over
its full range of travel.
4. Always install servos using the vibration-damping
grommets and tubular metal spacers supplied. The
rubber grommets provide some degree of protec-
tion from mechanical shocks and severe vibration.
Don’t over-tighten the servo retaining screws, as
this will compress the grommets and thereby redu-
ce the vibration protection they afford. The system
offers good security and vibration protection for
your servos, but only if the servo retaining screws
are fi tted and tightened properly. The picture on
the right shows how to install a servo correctly.
The brass spacers should be pushed into the rub-
ber grommets from the underside.
5. The servo output arms must be free to move over
their full arc of travel. Ensure that no parts of the
mechanical linkage can obstruct the servo in its
movement.
The sequence in which the servos are connected to
the receiver is dictated by the model type. Please see
the socket assignments listed on pages 35 and 37.
Be sure to read the safety notes on pages 3 … 5.
