Stick simulation via keys or switches
To use the functions of the proportional
channels #2 - #4 conveniently, you can
simulate the different potentiometer positions
of a stick, through a simple keystroke. If you
press the key S1, a joy-stick position is
simulated for position A.
Often the available joy-sticks are already
taken by other functions, but mostly the
remote control has still other free channels.
This schematic can be used for the further
channels to activate the additional sounds.
You need only 6 resistors and 4 switches for
each channel (or 2 reversing switches with
middle position). The small circuit can be
fastly build on a strip board.
With the indicated resistors values, this
schematic should work with all standard
remote controls. If needed, you can also
configure the thresholds of the 5 areas in the
Sound-Teacher.
How and where this schematic is connected in
the remote control, is unfortunately always a
little different according to manufacturer and
model.
However, in some (Robbe/Futaba) remote
controls an additional 68k ohms resistor is neccessary, which has to be placed in the
“S“- wire.
Tips:
Here again, we recommend using the diagnosis to check the circuit.
You can buy this circuit as fully constructed module from us:
SMS-R (for Robbe) and SMS-G (for Graupner and all other manufacturers).
