I'm sure there is nothing here to completely alleviate the disappointment you have with your current situation but I can tell you that you definitely knocked the complacency out of some of your fellow modelers.
I only use lipos for my Kero start turbines since they are power hungry when starting. I am embarrassed to say that I do store them, unplugged, in the models. After reading your thread, I pulled them all out, ran a quick storage charge on them and put them in a safe place. I never had a problem with lipos and hence my complacency.
I remember reading something that BVM posted a while ago about complacency with turbine start-ups and how many of us are not as diligent anymore about having the engine hatch off and have low extinguisher readiness.
Thanks for the reminders...
