I'm installing an Optic Kill switch but encountering a problem;

- Radio being used; Futaba 7C 2.4ghz

- using channel 5 to plug in Opti Kill switch (this channel used to be used for Flaperons)

- After instlling opti on the Ignition battery, the LED on the Opti switch comes on (indicating it's armed) Only when I apply Up elevator
- It comes on with up elevator even if Manual Ignition Kill switch is Off.

I'm obviously doing something wrong here as I know the LED is supposed to be on all the time indicating it's armed.
Is there something I must do with TX ie; channel 5 , it's the same effect either inhibited or with full ATV.

thanks in advance

DJ, I don't know your radio at all but the best way is to plug your kill switch into a gear channel or another non-mixed channel.
A flaperon channel is likely to be not only proportional but also dependent on other channels.

I have a JR setup and I plug my kill switches into the gear port on the receiver

Hi Apalson,
Channel #5 on my Rx is the gear channel.
I used to use it for second elevator servo (elevon)
Will inhibiting this channel change this or is a P Mix needed?

Mate, you may need to talk to some Futaba guys but your comments that it was used for elevon and the fact that the elevator position seems to affect your ignition indicates to me that there is still some mix active

That's correct, you must remove that channel from any mix you previously had it programmed into. Then in the Aux. channel menu program channel 5 to whatever switch you want to use for your engine shut off. If the it's armed in the wrong switch position, reverse it in the channel reversing menu.

Make sure all your mixes are off. Dan.

thanks guys, it works fine after reading your instructions.
