rapid changes in temperature (e.g. warm car : cold
environment) can result in condensation inside the
transmitter. Damp has an adverse effect on the
working of the transmitter, and on all other elec-
tronic devices.
If you detect damp in any electrical apparatus,
cease operations immediately, disconnect the
power supply, open the case (if possible) and allow
the device to dry out (may take several days). Carry
out a careful check of all functions when dry. If you
are in any doubt, have your equipment checked by
an authorised MULTIPLEX Service Centre.

This radio control system is only approved for
use on particular channels / transmission frequen-
cies, and these vary from country to country. In
some cases official formalities must be completed
before the system can be used legally.
Be sure to read the information sheets supplied as
part of the transmitter documentation!

General Safety Notes

Build the model carefully
• Install and adjust the control surface linkages in such
a way that the control surfaces move freely, and do
not bind at maximum travel. Don't limit servo travels
at the transmitter; it is always better to adjust the lev-
ers and pushrods to the correct lengths, as this helps
to keep slop (lost motion) to a minimum.
• If you observe these points you will minimise the load
on the servos, exploit their performance to the full
and achieve maximum longevity combined with best
possible safety and reliability.
• Provide effective vibration protection for the receiver,
battery, servos and other RC and electronic compo-
nents, to avoid electronic components failing under
stress. Read the notes in the operating instructions
supplied with these units. Naturally it is also impor-
tant to avoid vibration. Balance propellers and rotor
blades before use, and replace them if they are dam-
aged. Install glowplug motors using vibration-
damping mounts, and replace any power units or
components which are damaged or run out of true.
• Don't kink cables or place them under tension, and
protect them from rotating parts.
• Avoid unnecessarily long or superfluous servo exten-
sion leads. If they are longer than 30 - 50 cm, fit
separation filters (ferrite rings) and use cables of
adequate cross-section (voltage loss). As a guideline
we recommend conductors of at least 0.24 mm
• Do not coil up the receiver aerial, and don't shorten
or lengthen it. Do not deploy the aerial parallel to
electrically conductive parts such as metal pushrods,
or within fuselages with a shielding effect (made of or
reinforced with carbon fibre, metallic paintwork). Do
not deploy the aerial on electrically conductive model
components. We recommend the use of whip aerials
in large-scale model aircraft.
• Be sure to install a receiver power supply of ade-
quate capacity. For servos rated at up to around 40
Ncm you can use the following formula for calculating
the approximate battery capacity required:
Capacity
Always select the next larger battery size if weight or
space restrictions do not prevent you doing so.
• Moving parts made of conductive materials (e.g.
metal linkage components and pushrods) should not
be allowed to touch, as this generates "noise" which
can prevent the receiving system working properly.
• Avoid interference caused by static charges and
powerful electrical / electro-magnetic fields by taking
suitable suppressing measures (e.g. fit electric mo-
tors with suitable capacitors, petrol engines with
shielded sparkplug caps, ignition leads and ignition
units), and keep them well away from the RC system,
the receiver aerial, wiring and batteries.
• All cables in which high currents flow (e.g. electric
power systems) should be kept well clear of the RC
equipment. In particular, keep the leads between
brushless electric motors and their controllers as
short as possible (suggested maximum 10 - 15 cm).
• New models should always be programmed in the
peace and quiet of your home. Check all the working
systems carefully. Familiarise yourself with the
method of programming and operating your trans-
mitter before you take it out to fly your model.
Check your models regularly
• Control surfaces and linkages should move freely
and smoothly, without slop (lost motion)
• Pushrods, linkages, hinges etc. should be adequately
strong and in excellent condition
• Look for visual signs of damage such as fractures,
cracks, stress lines etc. on the model and its compo-
nents, as well as the RC and power systems
• All cables and connectors should be in perfect condi-
tion, and must make good, constant contact
• Check the condition of the power supply, its wiring
and the switch harness, and check the external con-
dition of the cells. Battery maintenance includes the
use of a suitable charger and a charge method
matching the battery type, plus regular balancing of
the cells and checks of their voltage and capacity.
Pre-flight checks:
• Carefully charge the transmitter and receiver batter-
ies, and your flight packs. At regular intervals check
their state of charge during and between flights.
• At the flying site check with those present which
channels / transmitter frequencies are in use, or reg-
ister with the flight director and ask about the method

.
of frequency control in use. Do not switch ON until
you are sure it is safe to do so. If you overlook this,
there is a danger of channel clashes!
• Carry out a range check (
• Ensure that you have activated the correct model
memory.
• Check all primary functions and auxiliary functions
one by one; they must all work correctly.
!
If you detect a problem or have any doubts:
don't fly. Look for the fault, correct it, and repeat
the checking procedure.
