Introduction: the XS-6 FM RACE radio control system
Always install servos using the vibration-damping
grommets supplied. The rubber grommets provide some
degree of protection from mechanical shock and severe
vibration.
Always extend the transmitter aerial fully before
operating your model.
Transmitter field strength is at a minimum in an imaginary
line extending straight out from the transmitter aerial. It
is therefore fundamentally misguided to “point” the
transmitter aerial at the model in the hope of obtaining
good reception.
When several radio control systems are in use on
adjacent channels, the drivers should always stand
together in a loose group. Operators who insist on
standing away from the group endanger their own models
as well as those of the other drivers.
Correct behaviour
Model cars should never be run on roads, footpaths,
public squares etc.
Take care
at all times
not to endanger people, animals
or other modellers.
Keep
well clear
of high-tension overhead cables. Never
run your model boat close to docks or full-size boats.
Pre-run checking
If there are several modellers at the site, check carefully
with all of them that you are the only one on “your”
channel before you switch on your own transmitter. If
two modellers switch on transmitters on the same
channel, the result is interference to one or both models,
and the usual result is at least one wrecked model.
Before you switch on the receiver, ensure that the throttle
stick is at the stop / idle end-point.
Always switch on the transmitter first,
and only then the receiver.
Always switch off the receiver first,
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 from other
transmitters and any interference, and may respond
unpredictably.
The model could then carry out uncontrolled movements,
which could easily result in personal injury or damage to
property. The servos may run to their end-stops and
damage the gearbox, linkage, control surface etc.; the
high current drain will also exhaust the receiver battery
very quickly.
Before
every
session check that the system works
properly in every respect, and has adequate range. This
means checking that all the control surfaces respond
correctly and in the appropriate direction to the transmitter
commands at a suitable ground range.
Repeat this check with the motor running, with an
assistant holding the model securely for you.
Installing control systems and 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 rubbing on
anything, or being obstructed mechanically at any point
in their travel.
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.
Models with internal combustion engines
It is important that you can stop your motor at any time.
With a glow motor this is achieved by adjusting the
throttle so that the barrel closes completely when you
move the throttle stick and trim to their end-points.
Receiver with integral BEC system
Caution: the power supply capacity of the
BEC system is limited!
If you wish to use powerful servos drawing a high current,
the BEC system must not be used as it would be
overloaded and immediately wrecked. In this case a se-
parate receiver battery
must
be used.
Batteries
Never
use faulty or damaged cells, or batteries consisting
of cells of different types, mixtures of old and new cells,
or cells of different makes.
Be sure to keep to our safety recommendations!
