[NSRCA-discussion] Electric/Glow Pros and Cons

[Fred Huber]

Do not leave the LiPos in the car fully charged. (at least not where the sun 
can get at them)

There have been a couple of instances of unknown cause Lipo ignition in hot 
cars... I think I found it (I got lucky)  Had a charged lipo in my car 
overnight and went out to unload the car about noon... found one swelled up 
LiPo. (luckilly one of my cheaper ones)

Not sure how hot it got inside the car but it was enough to cook the battery 
(which was where the sun could get at it through the car window...)

But then... the sun can heat your glow fuel can and pop the can.  And for a 
"neat trick" put an empty ("sealed" can in the car on a hot day, leave it 
overnight.. check the can out in the morning.  The new Powermaster cans will 
come out looking like they went through a trash masher.

If your TX is left on the seat in the car, you can badly deform the case. 
(gimbals may or may not still work)

Hot cars and RC stuff just don't get along well.  Its not just the LiPos...
