Just probing a bit:

If I get hold of a smart charger like el-John-o suggested, the risk is very much reduced? Is this something similar to glow fuel manufacturers stating that the fuel is highly inflammable? In day-to-day use, we never need to worry about the risk of fire, though we do take precautions for it

With a good charger, is the fire-proof cylinder needed? I normally charge my NiCds overnight and in the same room that we sleep in. Outdoors charging is not possible, I live in apartment type setup.

And finally, is it recommended to go electric anyway or get a profile like the Mojo or the Aeroworks ProX 260s?
