The Dell issues were not Lithium Polymer batteries, they were Lithium ion Cylindricals.. but those incidents do show how the cells can fail under worst case conditions. I am not saying that lithium polymer is a bad thing for RC.. all things fail.. and all things will fail badly given a high enough population.. from your kitchen toaster to the space shuttle... sh1t happens, but with lithium ion and lithium ion polymer, the abuse that RC cars (and their owners) increase the chance of this happening, and the outcome can be 'worse' than with NiCd and NiMH.... but lithium ion polymer is here to stay in one form or another...
