I recently bought a kill switch from rcexl. I hooked the kill switch to a switch that turns the power to the battery on and off.
The kill switch lights up to indicate that it is armed. No problem there. I am using a Spektrum DX8 transmitter. I originally
had the kill switch hooked up to the Aux 2 channel, but I couldn't get it to respond to off and on. Now I have the kill switch
hooked to the Aux3 {knob} channel of the receiver. I can now turn it on and off with the knob, but if I turn the transmitter
off the kill switch indicator light stays on. I was under the impression that if I turned off the transmitter the kill switch would
also turn off. I can't imagine that I have it wired wrong. Has anyone had this problem? Can someone show me a diagram
of how this should be wired with a switch? Thanks aframe2

Battery > Switch > Optical Kill > Ign

Use the monitor screen to see what channel is moving with the switch or to see what switch is moving the channel you have it hooked up to. I would hook it to a switch, not a knob, but thats a personal preference (based on a lot of experience though)

To kill on loss of signal, put the switch or knob in the kill position and rebind.

The optic kills I have turn off with loss of power to the plane not loss of signal from the transmitter...that would be a function of failsafe I believe

It should do both.

Not always,,

You must have the Failsafe set up like any other servo.
If you have it set to "Hold Last position" it will not turn off the Optikill,, it will hold it where it last was,, "On"

If you use JR/Spec. you want to rebind the RX with it in the off position on your TX,, If you use Futaba, set your failsafe within the TX

Hitec, Air??? not sure how those failsafes work


It's when you RX looses power it will turn off no matter what
