Do not place leads under tension or kink them;
protect them from rotating parts.
Avoid unnecessarily long or superfluous servo ex-
tension leads. Leads longer than about 30 to 50
cm should be fitted with separation filters (ferrite
ring # 8 5131 or separation filter lead # 8 5035),
and must be of adequate conductor cross-section
(voltage loss). We recommend at least 0.3 mm
Do not shorten or coil up the receiver aerial. Never
deploy the aerial parallel to conductive parts such
as metal pushrods, or inside fuselages with a
shielding effect (made of or reinforced with carbon
fibre, metallic painted finish). Do not lay the aerial
on electrically conductive model components.
Whip aerials are recommended for large-scale
model aircraft. Read the instructions supplied
with your receiver!
Ensure that the receiver power supply is of ade-
quate capacity. For servos up to about 40 Ncm
torque you can estimate the required battery ca-
pacity using the following formula:
Capacity [mAh] > Servo count x 200 mAh
If in doubt, always use the next larger size of bat-
tery unless weight or space make this impossible.
Moving parts made of conductive materials (e.g.
metal linkage components or pushrods) must not
be allowed to touch each other. They produce
metal-to-metal "noise" interference which has an
adverse effect on radio reception.
Interference caused by static charge and powerful
electrical or electro-magnetic fields should be
avoided by suitable suppression measures (e.g.
suppress brushed electric motors with suitable ca-
pacitors, fit petrol engines with shielded sparkplug
connectors, suppress ignition leads and ignition
units), and keep such items well away from the RC
system, the receiver aerial, wiring and batteries.
Maintain an adequate distance between high-
current cables (e.g. electric power system leads)
and all the receiving system components. In par-
ticular, the leads between brushless electric mo-
tors and their speed controllers should be kept as
short as possible (guideline: max. 10 to 15 cm).
The receiver can be shielded from interference
generated by speed controllers by the use of sup-
pressor filters (ferrite ring # 8 5146 or suppressor
filter lead # 8 5057).
Check your model at regular intervals:
Ensure that control surfaces and their linkages
move freely, smoothly, and without lost motion.
Ensure that pushrods, other linkages, hinges etc.
are stiff enough, and are in perfect condition.
Carry out a visual check for fractures, cracks, pos-
sible shear points etc. on the model itself, and in its
components such as the RC and power systems.
Check that all electrical leads and connectors are
in perfect condition, and are making sound contact.

It is essential to examine the airborne power sup-
ply and its wiring at regular intervals. This includes
the switch harness, and the external condition of
the battery.
Regular maintenance also covers the battery (con-
ditioning by repeated charge / discharge cycles),
and regular checks of the voltage curve and ca-
2
pacity. This requires the use of a battery charger
.
and a charge process which is suitable for the type
of battery in use.
Pre-flight checks:
Charge the transmitter, receiver and flight batteries
carefully, and ensure that they are in good condition
during pre-flight checks and between flights.
At the flying field your first job is to check with the
other modellers present whether your own channel /
transmitter frequency is free. If there is a flight di-
rector or site warden, be sure to register with that
person, and make sure you understand the type of
frequency control in use.
Only then switch ON!
Ignore this, and you risk a "channel clash" (two
transmitters on the same frequency)!
Carry out a range check with the transmitter aerial
fitted, but collapsed. (
Ensure that the correct model memory is active.
Check the function and effect of all primary and
secondary control systems.
!
If you discover anything doubtful: do not fly!
Locate the fault, eliminate it, then check again.
When operating the model:
If you have never flown a radio-controlled model, it
is really essential initially to ask an experienced
model pilot for help. A Trainer (buddy-box) system
is ideal for the first steps in learning to fly.
Models should only be operated at suitable sites.
Never fly or drive over or towards spectators.
Do not carry out any high-risk flying or driving ma-
noeuvres.
It is tempting to over-estimate your own ability and
skill. Don't do it: keep within your limits.
If you detect any sign of a problem or interference,
land or cease operations immediately.
Caution: static electrical charges!
In extremely dry air (in mountainous terrain, in a
mountain bowl, close to weather fronts) static
charges tend to build up in the transmitter and / or
the pilot. The discharge takes the form of static
sparking, which can endanger the pilot, and cause
interference or damage to the transmitter.
Counter-measures:
Cease operations as quickly as possible, and walk
a little way down the mountain in order to find a
less exposed location.
