I have crashed my electric mini flyers almost 1000 times with my 3cell 700mah lipos and they just keep on going.... I am just waiting for the fire to start someday.... You guys really take it overboard, please send all your dropped lipos to me I can really use them..... If they were so sensitive they would blow up on planes and during shipping when boxes get kicked around.... its not nitroglycerine we aretalking about....  Lipos only blow when overcharged, if they are punctured they usually take awhile to fire up !!
