Ron,
That may all be true, but think about it. None of the lipo powered toys we play with are necessary. There are still fuel engines that can power cars and airplanes just as well as the lipo packs we now use for power. There are also some great LIFE/A123 batteries that are usable if you insist on electric power. These are alternatives even though they may not be as good as lipos. This may be inconvenient or not what you want to hear, but I really hope that none of my fellow modelers will ever have to live with loosing their valuables, or worse yet a family member due to our hobby choices, and living with the realization that it could have been prevented by using an alternative power source.
There are many products that were used daily by everyone, that are now banned because of the danger of using them. Everyone thought they were safe too.
