Butterfly Mixer Circuit

Posted on Apr 23, 2012

If the transmitter stick-potentiometer delivers a voltage about 2 - 3 V, this circuit will be suitable. If you want to avoid using the battery cable (supplying Vcc for IC1and -2), you can use a separate 5V supply for IC1 and -2. In that case you should test the mixer function when the battery voltage is low.

If the circuit is used as a butterfly mixer, instead of the rudder potentiometer the aileron potentiometer must be connected, and instead of the elevator potentiometer the following simply circuit can be used:
