Jester you are definitely entitled to your opinion. OTOH I suggest you think about the numerous ways to avoid accidents such as a battery jumping out of a batt. box. I can solder. I can wrap tape around the batteries in the box. I can clean contacts every flying session, but I don't! HA! I don't worry or find small points to make me look smart. I simply pass on easy ways to accomplish things that I have experimented with.. Since I have no yearning for electric motors outside a boat, I don't think you find me telling folks how to do electric airplanes. So perhaps the readers may get a better chunk of information here if we all simply discussed the pluses and minuses of methods we use and/or used, and how things worked for us as an individual. That way we all have a chance to learn, rather than simply plant ourselves as some kind of expert. "It's not so much what we DON'T know that can hurt us as it is that which we know for sure that ain't so."
