I've seen a LiPo go up at a race meeting - it's not funny at all. In fact, the speed in which the fire took was truly a wake up call to everyone that was there.
It is true to say that all batteries (in fact all stored energy) have some form of danger attached to them. However, generally speaking, with a NiMh, you get an explosion. Nnot nice, but once it's done, it's done. With LiPo, you get fire, that continues until someone puts it out - and the smell afterwards is nothing short of horrific.
I don't mean to make everyone too scared to use their kit, but you do have to be careful.
