receive installation advice

13.1

receiver aerial

The receiver aerial is directly connected to the receiver . The length is
20 cm and may not be lengthened or shortened. The aerial should be
located as far as possible from electric motors, servos, metal linkages/
pushrods or power cables etc.
Lead the aerial, using the typical car aerial tube to the outside of the
vehicle.
The 2.4 GHz FHSS receiver is not fitted with a ceramic filter and con-
sequently
insensitive to vibration compared to receivers of
the previous technology generation. The frequently used practice of
wrapping the receiver in foam
to protect from vibration is unnecessary with the 2.4 GHz FHSS recei-
vers.
This well-meant measure is counter productive, since in the 2.4
GHz receivers, high performance I.C.s with high current drain
are in use (similar to a Laptop), that leads to noticeable heat generation
. Wrapping the receiver in foam insulates it and prevents the heat build-
up from dissipating from the receiver.
nicht vom Empfänger abgeführt werden.
We recommend mounting 2.4 GHz receivers with double-sided adhe-
sive tape with a foam core (or Velcro strip).
If possible, not over the entire area but on "feet" to enable air to circulate
around the receiver.
Mounting it vertically improves the air circulation.
The temperature range for remote control components is generally bet-
ween -15 °C and +55 °C.
This is the typical range specified by electronic component manufac-
turers.
Hersteller von Elektronikbauteilen angegeben wird.
This range is applicable to all receivers, of both the old and new genera-
tions of 2.4 GHz FHSS receiver.
Receivers from other manufacturers also operate in this temperature
range.

13.2 switch Harness / servo leads / servo suppression filter

The switch of the receiver system must be able to operate in both direc-
tions without any mechanical binding. The cut-out in the chassis must
be large enough to suit. With i.c. powered models, the switch should be
mounted on the opposite side to the exhaust outlet, so that no oil can
enter the switch and contaminate the contacts.
The On position of the switch should be to the rear of the model, so
that the receiver system does not get switched off accidentally in an
accident
When installing servo leads, please ensure that they are not under any
mechanical strain and are not kinked or bent tightly, as this might cause
them to fracture over time. Make sure there are no sharp edges, which
might damage the cable insulation.
All connectors must be firmly fitted and secure. When disconnecting
servo plugs, pull on the plastic housings - not on the wires. Servo leads
should not just be left trailing loosely inside the fuselage; it is far better
to attach them neatly to, say, the fuselage side or the chassis using
adhesive tape or cable ties.
No modifications are allowed to be made to the radio system. Avoid
reversed polarity and short-circuits of all kinds, as the electronics are
not protected against such errors.
If you wish to use long servo leads or extension leads, please note that
interference may be picked up via the over length cables. Therfeore, if
the servo leads are longer than two normal extension leads (50 cm),
use twisted cable (No. F1452005).
even better: use suppressor filters, no. F 1413.

To fix the servos, always use the supplied rubber grommets and brass
ferrules. Take care when tightening the servo screws that they are not
overtightened and bear on the ferrules. The vibration damping effect of
the grommets will be lost and this can lead to servo damage.
The servo installation in RC car models is made into the prepared aper-
tures in the mounting plate. With boats, you can use the robbe quick
servo mounts. Take great care when installing servos since servos
react very sensitively to vibration.
The following diagram shows two typical methods of mounting servos.
Diagram "A" shows a wooden servo plate. Diagram "B" shows the use
of a plastic or aluminium plate.
Splined servo output arms make the mechanical setting of the servo
neutral possible.
setting the neutral position:
Remove the fixing screw from the output arm, remove arm, move to the
desired neutral position, replace and tighten screw.
effect:
To achieve the smallest adjustment (3,6°) towards the RIGHT, move
ARM 2 to the next available position on the Base Line A. ARM 2 must
be set to the next possible position on the Base line A , ARM3 then
has an adjustment od 7.2°, ARM4 has 10.8°. To achieve the smallest
possible movement to the LEFT, ARM4 must be set to the next possible
position on the Base line A.
sub division:
The servo splined output shaft and the servo output arm are sub divi-
ded into 25 segments. The change in angle per segment is 360°: 25
= 14,4°. The minimum adjustment posible is defined by the number of
ARMS per output disc. A 4-armed disc has a minimum adjustment of
360° : (25 x 4) = 3,6°. A 6-armed output has a minimum adjustment
of 2.4°. ARM 2 moves 2,4° to the right, ARM 3; 4,8° to the right, ARM
6; 2,4° to the left, ARM 5;, 4,8° to the left, ARM 4; 7,2° to the right and
left.
Different servo arms are available for robbe servos. They are shown in
the following illustration. Additionally, the angular position change per
splined arm segment is also shown.
