You have to set the failsafe on your transmitter channel to turn off the Cutoff when you
turn off your radio. The Cutoff has no way of knowing if your transmitter is on or off
if you do not set your failsafe correctly.
Hello. I purchased a Smartfly Opto ignition cut off last November. I installed it in my Staggerwing Beech. Every thing works fine except for one thing. The ignition doesn't cut off when the tx signal is lost. Hope you can help me on this.
