I am so glad I haven't had a lipo fire. Seeing all those ruined planes almost makes me want to go out and buy a clay pot an fill it with sand. Right now, I only have 1 910 mah lipo that I'm using in my foamie. I monitor that thing like a security camera watches its post.

I have had a 2100 have to many amps drawn out of it. It just quit on me, and decided to puff up. Another 2100 had the corner smashed in when a flight didn't go as expected. Nothing major happened, like puffing up, or even getting warm.

When you say "see all those ruined planes", consider if there are all that many. A lot more other (destructive) things happen to planes, like bad servo plugs, loose motor mounts, etc. I am sure that a lot more planes went up in smoke from spilled nitromethane than from lipo fires.

loss of a glow powered model to fire is so rare I have never seen it happen and I have flown RC for over twenty years. Have I seen a fire in an E-powered model , as the wattage goes up, so do the risks of fire

Glow aircraft fires are exceedingly rare, like the previous poster mentioned.

I have seen exactly two in 40 years of extensive modeling. I had a small control line model catch on fire while starting and burn the covering off, in the 1960s.

I have seen one R/C glow model burn after a crash...the alcohol fires are nearly invisible, but the smoke is not.. (RX battery was undamaged and ejected from the crash, so it was not battery induced)

Lipos have, by far, the greated possibility of a fire happening during use, except for a good turbine jet crash.....

Lipo storage (1 min 34 sec)


I found this video on you tube. Not being able to leave these batteries unattended while charging is a nuisance. is anyone of the opinion that if they are being charged in a fireproof container it is ok to leave them unattended?

Here's my take on it, and mine alone. Do what you will, but I'm not responsible.

If the lipo goes off, there is nothing you can do to stop it. So, whether you are there or not is actually not going to matter much, unless you are there with the right kind of fire extinguisher in your hands. So, you might as well always charge in a fireproof container whether you are going to stand around and observe it or not. Just because you are there, don't assume you can charge without any fire protection, as they tend to move around shooting flames out, so anything flammable nearby is going to be messed up. So, no matter what, fire proof container unless you charge outside in the desert or something. The other thing is that the smoke is horrible and very corrosive. If it is in your house or garage, then you will suffer much smoke damage even if you are there with a fire extinguisher to put it out. You are better off making sure that you are able to charge safely if you are there or not. Especially since according the murphys law, the thing will only ignite when you are called inside to answer the phone or do something for the wife. You can sit around and charge all day, and the 1 minute you leave is when the fire will happen. So, you might as well secure your charging area pretty well, and not have anything in the area that you care too much about, except of course for the charger. I think that just like forest fires, STD's and teen pregnancy, the best bet is prevention. Make sure your cells are well taken care of. Know your charger, and never assume anything about the settings. I use a cellpro 4s, because I can't screw it up. I charge in a large clay flower pot, sitting on a clay base, and then I have a base from a larger flower pot to sit on top. It will contain fire very nicely. There's nothing I've seen yet to stop the smoke. What I would really like to do would be to build a small brick or cinder block bunker to charge in, so everything is protected from rain and all that, but no smoke or fire can possibly damage the house. or have a small fire proof enclosure in the garage than vents out to the outside by a fan with a duct, so no smoke can damage anything. That's an expensive and cumbersome way to go, and not likely to happen, unless I win the lottery and build a mega-house. Then I would have a workshop with one of those vent hoods for doing nasty chemical reactions in, like in chem class. Lots of ventilation. Sealed in cabinet with plexiglass windows, with the thick gloves mounted in them.
That's probably about the only thing that could ever truly be considered safe. Just having them in the house or car is a risk. However, life is not without risks. We are probably much more likely to slip in the tub and die than to ever experience a lipo fire firsthand.

Very well stated. That sums it up very nicely.
I think I'll add it to my list of Informational Threads if you don't mind. http://www.rcgroups.com/forums/showp...06&postcount=8

@Fuegodeth:
The only thing I don't understand in your post ist the acronym "STD", but anything else is a big thumbs up from me.

As with motorcycle accidents, most lipo fires are due to missuse, like wrong charger settings etc.

As for nitro fires... I fly models for about 30 years now and have seen at least 10 of those. Mostly they came from refueling while the motor was running, probably spilleage on the manifold and then som cause of ignition (I never saw one in theair, though). I never was anywhere near the fires. And again: It's not the nitro that's dangerous - its the careless people handling it.

Now what is STD, anyway? I know one horrible thing always to avoid, but that's called "Ford LTD"

I see hoppy already covered that. Thanks much. I didn't want to have to get into a detailed explanation. From what the news is saying, with the advent of viagra and such, they are now a rampant problem for elderly nursing home populations. Much scarier than a mere lipo fire, or at least that aspect is. wouldn't want to be a doctor in one of those places.
