You have seriously been flying for 45 years Minnflyer?

You start when you were a baby or are you just REALLY old now!
But seriosly, you don't use a voltage tester? I never put a plane in the air without checking the tx and rx voltage. I also think I have a touch of obessive compulsiveness because sometimes I check it 3 or 4 times before each flight. Or maybe I am just paranoid.
You like living on the edge?
