Have been using an RcXel kill switch on my DLE 20 for almost 2 years
without a single problem. Using Futaba 8 UAP trans with a frSky 2.4
conversion. Now when I shut the trans down the engine keeps runing
when it should shut down. Have tried a new receiver and still the same.
I am using channel 5 to control the ignition switch and it does work properly
Shutting down the engine.

Any thoughts on the cause?
