11. Starting up the receiver
a) Receiver connection
The receiver offers connection options for up to three servos (CH1, CH2, CH3) and a receiver battery pack (B/VCC).
Figure 5a shows a connection chart for a model with external receiver power supply (figure 7a, item 1), as it is com-
mon, e.g, for a combustion model.
Figure 7b shows a connection chart for an electrically powered model in which the speed controller has an integrated
BEC (BEC is a receiver power supply integrated into the speed controller). The driving battery (figure 7b, item 1) is
connected to the speed controller (figure 7b, item 2) here. The BEC integrated in the speed controller supplies the
entire receiver system with power through the connection of the servo plug from the speed controller to CH2.
If the speed controller used does not have any integrated BEC, the receiver system must be produced with an external
receiver power supply. Use figure 7a as reference. In this case, only the servo Servo 2 (CH2) needs to be replaced
by the speed controller.
Note:
If an electronic speed controller with integrated BEC is used in a model, no external power supply must be connected
to the receiver, since this may destroy the speed controller. The BEC may be disconnected from the receiver system
for use of external receiver power supplies if you separate the middle, red wire at the servo plug of the speed controller
and insulated it.
If necessary, alongside the steering servo on the receiver outlet “CH1” and the accelerator servo/drive regulator on
the receiver outlet “CH2”, an additional servo can be connected to the receiver outlet “CH3”. This servo than takes on
the switching tasks or other functions on the receiver at the touch of a button.
With a electric model with a mechanical drive regulator, a battery box or a separate receiver battery pack is required
for the power supply of the receiver in all cases. The power supply connection mounted to the mechanical drive
regulator may not be used since the voltage at the plug of 7.2 V (for a 6 cell drive battery) is too high for the receiver
and the connected servos.
Pay attention when connecting servos to always ensure the correct poling of the plug connector. The plugged contact
for the impulse cable (yellow, white or orange according to manufacturer) must be connected to the inner (left) pin
contact. The plugged contact for the minus cable (black or brown according to manufacturer) must be connected to
the outer (right) pin contact.
Switch the transmitter on and then switch the receiver on. If the Binding function is correct, the red control LED on the
receiver will light up. Check the correct functionality of the receiver and then switch it back off.
If the LEDs in the receiver do not light up or the connected servos do not react to the remote control
signals, the Binding function must be carried out. More information can be found in the later Chapter
"Binding function".
