Got the components for mine already, but have not assembled it yet. I will do so within the next couple of days

I have three packs that need to be discarded properly, all three are Thunder Powers mind you.

All of my packs have Deans Ultra female plugs. I was lazy and simply soldered a bulb to a male Deans connector. Works fine. I do not cut, chop, pierce or otherwise multilate a discharged lipo however. Cut and tape the wires of a fully discharged pack and dispose of in the trash is what I was told.

SntaCruz83;

You're not alone my friend.. I just built my second plane - a Pico Tiger Moth and was all ready to get a lipo when I read this thread. Man, it feels like inviting Charles Manson into your basement (ok a bit .. or more than a bit of drama). It amazes me that they can even ship these things through the mail. It seems like good ol American ingenuity would have figured something out by now in regards to making them less volatile.

Anyway, now I'm second guessing the Lipo because I know I'll be crashing..

Joe,

Don't worry, the TM will not catch your lipo on fire when you crash. It is too slow and light to really hurt the battery. That is a very popular plane, i have seen it fly many times, and also crash. Trust me, the TM will not crash so bad that your plane will be in pieces.

Just get a good lipo balancing charger, I got into lipos just a few months ago, so far no problems. Plus, I have heard of people getting 30+ min flights using lipos.

My Pico T/M has well over 500 flights under its wings, and I have yet to crash it. It is on its fourth factory motor.

400 plus of those flights have been using Li-Pos, 28 plus minute flights with 640 mil two cell Li-Po packs are the norm. I have seen T/Ms snap their wings in flight after a series of wild loops. Wings get glued back together and the T/M is airborne in no time flat.

The reason for wings snapping is due to the rather powerful brushless motors some owners put up front. Them motors and the T/M wings don't get along too well under such stressful flight conditions (for the wings, that is).

I don't remember where, but there is a thread here that lists the causes of various fires (if known) and the conditions of the accident(S). I asked the same question last year and got a quite a few responses; to make a long story short there were no acutal verified inicidents, BUT there were a number that were mysterious that seemed to have no other explanation...
So - when I asked the same question the answer was "it's possible."
Still makes me nervous. I use a battery bunker, watch them charge for a few minutes after starting, and am careful to make sure all wires are insulated... Still, when I have them sitting and waiting for next week's flying I worry. I usually keep them in the battery bunker between flight days. Another tip was to not store them in a fully charged state, always keep them below 70% when storing.

Better be safe that sorry. How puffed up is it? I'm in the camp of "I'd rather lose $30 than my house," so I'd toss it.

If you do decide to dispose of it, make sure it's fully discharged. Or you could just take it to a RadioShack.

I agree. Discharge it and toss it. Once it balloons it is a goner anyway, in your case it also got hot. Not good.

I've been one of the resisters of lipo although I did have a couple ofthe original etec packs. Both of them are long puffed and gone but I am now converting over to lipo. I am one of those naturally cautious people and would always prefer to manually set the charge rather than trust some device to get it right. Even with doing it myself, I still charge my lipos in a heavy ceramic crock with a lid and carry them in a sturdy metal container.

Mistakes with nimh can ruin a pack but mistakes with lipo can ruin a plane, car or house!

Here are some options.

1. Carry them with you. Better safe than sorry.

2. Put them into a firesafe. Sentry makes some, and they're for sale at Wal-Mart for about $20. That's where I store mine *and also inside of a LipoSack.
