27. OPERATING ADVICE
All robbe-Futaba receivers will continue to operate with the same
range even when the power supply drops to 3 Volts. This is an
advantage when even one cell in the pack ceases to function
(short circuit), you will retain full control of your model. Although
the servos, which require 3.6 V, will operate at a lower speed and
torque. This is very important in low winter temperatures to avoid
a break in control, which might occur and caused by reduced
voltage due to the cold temperature.
However, this can be a disadvantage inasmuch that you might not
notice that a cell has ceased functioning. Therefore, the receiver
battery should be checked periodically.
It is recommended that you use the robbe battery monitor
No.8409, which can show you the current receiver battery voltage
by means of a LED display.
27.1 TX/RX SWITCH ON/OFF SEQUENCE
Always turn the Tx on first, followed by the receiver. To switch off,
always turn the Rx off first.
If there is a Tx signal, the Rx commands the servos to go safely
and under full control to their neutral position. Before driving the
model, you should check all functions by moving all the controls
on the Tx. Also check that the servos are moving in the correct
direction or “sense” in relation to the Tx control. If this does not
occurs, then reverse the direction of throw using the REVR func-
tion described in chapter 22.
27.2 ELECTRICAL NOISE
For reliable, interference-free operation of your model, “metal-
to-metal” electrical interference must be avoided. This can occur
when individual metal parts of the model are allowed to contact
against each other under vibration. The throttle linkage of an i.c.
motor is a common source of this. Therefore, you should always
use a plastic quicklink for the throttle arm connection to the motor.
If a metal-to-metal linkage is inevitable, both parts should be elec-
trically earthed together by soldering a flexible wire to both metal
components.
27.3 ELECTRIC MOTOR SUPPRESSION
All on-board brushed elec-
tric motors MUST be sup-
pressed; otherwise the
arcing or “brushfire” that
exists between the brushes
and commutator will cause
constant interference and
loss of control.
We recommend using the
robbe suppresion filter kit
No.8306 or the capacitor
kit No.4008. Every brushed
motor must be individually suppressed as in the illustration.
27.4 BATTERY ELECTRONIC IGNITION
The increase in popularity of spark ignition motors has meant that
the ignition system can be a source of interference on your radio.
Always power the ignition from a separate battery. Use resistor
suppressed spark plugs and shielded plug leads. Locate the re-
ceiver system in your model as far away from the ignition and its
battery/switch as possible.
