The channel numbers of the SFR-1 have nothing to do with the channel numbers of
your receiver. You do not have to connect channel #1 of the receiver with channel #1
of the SFR-1. If the joystick (to accelerate your model) is for example at channel #3
of the receiver, you have to connect channel #3 of the receiver with channel #1 of
the SFR-1.
BEC – receiver supply voltage
The SFR-1 has its own BEC supply voltage of 5,6 V an additional receiver battery is
not required. The maximum continuous BEC current is 3 A. A current of 5 A is
possible for a maximum of 10 seconds.
In case the BEC voltage of the SFR-1should not be used, the red cable from all
servo cables from proportional channels #1 - #6 must be disconnected!
Connection of loudspeaker
The loudspeaker ist connected to X7 at the SFR-1.
The red cable is connected to the positive and the black to the negative pole of the
loudspeaker.
The supplied loudspeaker connection cables should not be extended to prevent
interference of the receiver (especially with FM systems)! The loudspeaker cables
should be installed with a maximum of distance to receiver and antenna.
