You beat me to it! So-called "hot" model engine (and dragster) fuels are mostly nitromethane. However, nitromethane has been described as "the simplest nitrogen-based high explosive" -- and, packaged with an appropriate oxidizer, is sold as a commercial binary (mix immediately before use) explosive. (Deliberately being vague here...)
Of course, R/C transmitter/receiver/servo combinations have been used by middle eastern terrorists to trigger bombs.
BTW, were any of you FReepers aware that those suspected of bombing the Murrah Building in OKC visited a model shop shortly before the bombing? And that an Iraqi caught an overseas flight from OKC shortly thereafter -- and that his luggage was found to contain "several car radios and other bomb-making materials and tools". (So-described by Italian customs, who discovered them.)
I've often wondered if mis-translation masked the true nature of those "car radios"...
I build models -- and certainly don't advocate shutting down our hobby. OTOH, A good "Heads-up" to model shops across the nation seems in order...
-----------------
Of course, nowadays, the terrs seem to favor cell phones for triggering bombs.
Hmmm -- perhaps a computer program that rapidly and repeatedly cycles through all cell numbers, giving each a ring... Might give some terrorists a few nasty surprises...
