Safety Notes
Safety Notes
Ensure that no metal parts are able to rub against each
other, e. g. when controls are operated, when parts
rotate, or when motor vibration affects the model. Metal-
to-metal contact causes electrical “noise” which can
interfere with the correct working of the receiver.

to-metal contact causes electrical “noise” which can

Directing the transmitter aerial
Transmitter fi eld strength is at a minimum in an imagi-
nary line extending straight out from the transmitter
aerial. It is therefore fundamentally misguided to “point”
the transmitter aerial at the model with the intention of
obtaining good reception.
When several radio control systems are in use on adja-
cent channels, the pilots should always stand together in
a loose group. Pilots who insist on standing away from
the group endanger their own models as well as those
of the other pilots.
However, if two or more pilots operating 2.4 GHz radio
control systems stand closer together than 5 m, the
down-link channel may be swamped, triggering a very
premature range warning. If this should occur, walk
away from the other pilots until the range warning
ceases again.

Pre-fl ight checking
Before you switch on the receiver, ensure that the throt-
tle stick is at the stop / idle end-point.

Always switch on the transmitter fi rst,
and only then the receiver.
Always switch off the receiver fi rst,
and only then the transmitter.
If you do not keep to this sequence, i. e. if the receiver
is at any time switched on when “its” transmitter is
switched OFF, then the receiver is wide open to signals
is at any time switched on when “its” transmitter is
switched OFF, then the receiver is wide open to signals
from other transmitters and any interference, and may
respond. The model could then carry out uncontrolled
movements, which could easily result in personal injury
or damage to property.
Please take particular care if your model is fi tted with
a mechanical gyro: before you switch your receiver off,
disconnect the power supply to ensure that the motor
cannot run up to high speed accidentally.

Please take particular care if your model is fi tted with
a mechanical gyro: before you switch your receiver off,
disconnect the power supply to ensure that the motor
cannot run up to high speed accidentally.
As it runs down, the gyro can generate such a high
voltage that the receiver picks up apparently valid
throttle commands, and the motor could respond by
unexpectedly bursting into life.

Range checking
Before every session check that the system works properly
in all respects, and has adequate range.

Secure the model
adequately, and ensure that no persons are standing in
front of the model.
Carry out at least one complete function check on the
ground, followed by a complete simulated fl ight, in order
to show up any errors in the system and the model’s
programming. Be sure to read the notes on pages 62
and 71 in this regard.
When operating a model, i. e. when fl ying or driving,
do not operate the transmitter without the aerial fi tted.
Check that the transmitter aerial is fi rmly seated.

Operating your model aircraft, helicopter, boat or car
Never fl y directly over spectators or other pilots, and
take care at all times not to endanger people or animals.
Keep well clear of high-tension overhead cables. Never
operate your model boat close to locks and full-size ves-
sels. Model cars should never be run on public streets or
motorways, footpaths, public squares etc..

Deploying the receiver aerial(s)
The receiver and its aerials should be installed as far
away as possible from all kinds of power system. If your
model has a carbon fi bre fuselage, the aerial tips must
always be deployed outside the fuselage. The orientation
of the aerial(s) is not critical, but we recommend install-
ing them vertically (upright) in the model. If the receiver
features aerial diversity (two aerials), the second aerial
should be arranged at 90° to the fi rst.

Installing the servos
Always install servos using the vibration-damping
grommets supplied. The rubber grommets provide some
degree of protection from mechanical shock and severe
vibration.

Installing control linkages
The basic rule is that all linkages should be installed in
such a way that the pushrods move accurately, smoothly
and freely. It is particularly important that all servo output
arms can move to their full extent without fouling or rub-
bing on anything, or being obstructed mechanically at
any point in their travel.
It is essential that you should be able to stop your motor
at any time. With a glow motor this is achieved by adjust-
ing the throttle so that the barrel closes completely when
you move the throttle stick and trim to their end-points.
