Now the set up and testing....
This is where the multimeter comes in very handy. However, if you dont have one, a 6volt bulb plus a 6 volt battery and some wire would suffice.
First of all, we need to connect up our switcher to our RX. Any channel, apart from the throttle channel. I used the rudder channel for the set up - number one. I switched my transmitter on first and then switched the power on to my RX.
Then, I connected up the probe from the multimeter to the outlet on switch one. My multimeter was connected across the terminals of switch one - one side common and one side normally closed.
I moved the transmitter stick full over to the left, until I heard the relay click. This indicated that the relay had switched. This was shown on the meter.
I then moved the stick on the transmitter in the opposite direction which re-energised the relay switching it back on.
Now with this set up, on this switcher please remember you have to move the stick on your transmitter from centre to its extreme once & back to the centre. This switches number one relay on.
Do it twice and this switches relay number two on.
Do it three times and this switches number three on.
Do it four times and this switches number four on.
Now - if we move the stick in the opposite direction the same amount of times, it de-energises the relays in turn. 4,3,2,1
It takes some time to understand the operation of this switcher and also the movement on your controls.
But, once you have mastered them and understand them it becomes fairly straight forward - its a case of the man has to get used to the electronics set up and not the electronics getting used to the man
Once you are satisfied with the operation, we move on to the last stage and that is fitting it into the box. It is honestly just a case of drilling 12 holes or 2 large slots if you prefer in either end of the casing to facilitate your cables or your wires plus a hole in the side to facilitate your RX lead.
