Luckily, my model is salvageable and I'm a bit wiser about the advisability of using remote ignition kill switches.

Yes I, having the same experience also concluded it's a vibration issue. I have used all of the other brands of optic kills since then, including one in the airframe that was fitted with the 42 percent unit. No other brand had a problem like this.
