Default RCexl Opto kill switch not turning off when I turn Radio off

I have a Futaba T6ex . I have the opto switch hooked up on channel 6 ( flaps ) !

When I turn off receiver battery, the opto switch led goes off ... Ok
But when I turn off the radio it stays on .. So I am thinking if my radio goes dead the plane
engine wont shut off and I think it is supposed to right ??
Puzzled
Thanks
David

David, you have to set your Failsafe so that in the event of signal loss your channel 6 default setting is off.

Fail safe for the 7 channel mode RXs is "hold" except for throttle which comes back to idle, you can only program fail safe on other channels in 10 channel mode, you'll need a better TX/RX combo

EX manual,,
F/S Fail Safe (Throttle channel only)The Fail Safe function is recommended to use for safety reasons in the event of radio interference. In this menu, you may
select from one of two options. The NOR(normal) setting holds the servo in its last commanded position, while the F/S(Fail
Safe) function moves the servo to a predetermined position.
The setting is set to F/S as a default.
The use of the failsafe function is recommended from the standpoint of safety. You may wish to set the throttle channel so that
the throttle is moved to idle when theres interference. This may give enough warning to allow you to fly towards yourself and
recover from the radio interference. If you choose to specify a failsafe setting, the failsafe data are automatically transmitted to
the receiver many times during the flight.

The RCexl switch automatically turns off your ignition if you have a receiver battery failure. But the guys are right that the only way it will do that with a transmitter failure is if the receiver is set to failsafe at "down" or "off" on that channel.
