The receiver must be aligned at right angles to the copter on the
receiver platform. The lower surface of the receiver must always
be parallel to one of the copter sides. Prior to installation, remove
the sticker on the back of the receiver. We recommend using
double-sided tape No.: S8376 for Gr-18 to fix the receiver in
place.
Binding
Binding is only possible if the receiver has not been linked with
a bound transmitter since being switched on (red LED lights).
Press the SET button to set the receiver to BIND mode.
If you wish to bind the receiver to a new model memory, this is
the procedure:
 Switch the transmitter's RF section off in the "Basic model
settings" menu (see transmitter manual)
 Switch on the receiver and put it in binding mode, by press-
ing and holding the binding button (green and red LED on
the receiver are flashing)
 Initiate binding in the transmitter's "Basic model settings"
menu.
 If the red LED of the receiver goes out within about 10 sec-
onds and the green LED is illuminated, the binding process
has been completed successfully.
 Your transmitter/receiver combination is now ready for oper-
ation.
 If the red LED is still lit, the "binding" failed. In this case,
repeat the whole procedure.
Connect the speed controllers or servos to the row of sockets
on one end of the receiver. The connectors are reverse polarity
protected: note the small chamfers on the sides. Never use
force – the connectors should engage easily. The polarity is also
printed on the receiver; the negative wire (-) is brown, the posi-
tive (+) red and the signal orange.
The servo sockets of Graupner HoTT 2.4 receivers are numbered
sequentially. The socket for channel 6 can also be programmed
to deliver a (digital) sum signal (see following section).
Power supply
The receiver does not feature specific sockets for connecting
the battery. We recommend that you connect the power supply
to the socket(s) close to the servos already connected to the
receiver. If you wish to connect multiple separate batteries, the
