11. Initial Operation of the Receiver
a) Receiver Connection
The receiver allows you to connect up to 3 servos/drive control units
(receiver output 1, 2 and 3) and a receiver rechargeable battery
(receiver connection B), which are equipped with Futaba connectors
(with reverse polarity protection).
Alternatively, you can also use servos/drive control unit with J/R
connectors.
When connecting servos and drive controls, always make sure to pay
close attention to the correct polarity of the plug connectors. The plug-
in connection for the positive lead (yellow, white or orange, depending
on the manufacturer) must be connected to the inner pin contact. The
plug-in connection for the negative lead (black or brown, depending
on the manufacturer) must be connected to the outer pin contact.
Depending on the model for which you use the remote control system, the connection as well as the power supply of
the receiver and the servos can be carried out in different ways:
Receiver socket
Combustion models
Electric car models
Ship models
CH1
Steering servo
Steering servo
Rudder servo
CH2
Gas servo
Drive control unit/servo
Drive control unit/servo
CH3

Note:
*
If necessary, it is possible to connect an additional servo to receiver output 3 - in addition to the steering servo on
receiver output 1 and the throttle servo/drive control on receiver output 2. This servo carries out switching or other
functions e.g. as a secondary braking servo.
** For electric models with mechanical drive control units, a battery box or a separate rechargeable receiver battery
is always required for the power supply to the receiver. The power supply connection mounted to the mechanical
drive control must not be used because the voltage of 7.2 V applied at the connection (in a 6-cell rechargeable
drive battery) is too high for the receiver and the connected servos. The receiver or the servos will be destroyed
and the warranty/guarantee is void!
For electric models with electronic drive control, a separate rechargeable receiver battery is only required on the
B connection if the engine control/flight control used does not have a BEC switcher. Drive control units with a BEC
must not have anything connected to "B". For further information, refer to the technical documents of the drive
control unit.
If a separate receiver battery is used, we recommend the use of a 5-cell rechargeable battery pack
(only use 4 cells if using disposable batteries!) or a so-called "Hump" rechargeable battery pack.
This avoids possible technical malfunction as a result of low output voltage from rechargeable batteries
(cell voltage for rechargeable batteries = 1.2V, disposable batteries = 1.5V).
