Trust me.... it's not my intention to draw any such conclusion.

I wonder if we are right and in fact not many of our fellow slopers are using Lipos ...... Or...... They are using but not telling us because we've ascribed such a stigma to it. ( the post above being an example...although, to be fair, he IS telling us!)


Turth be told, Ian, I don't disagree with any part of your statement, but I'm still interested in the incidents however rare they might be. Not to minimize the potential for danger, but to learn.
As I'm sure you'll agree, there are myriad other factors that play in this and, seeing as we probably won't be able to ignore the proliferation of Lipos for much longer, it's best to get ahead of the curve and learn about them - "them" being the incidents- however rare their occurrence might be.

And to remind everybody, I'm interested in glider crashes ..... i.e. No motor and no ESC.

...Just in case you think Ni based cells are completely safe.
This was the result of a 20 something cell e-sailplane from Shred-Air going in @ LosBanos.

I wouldn't expect something like a small 500-700mAh 2S LiPo or LiFePo4 pack to be very dangerous in slope gliders. Out of the few packs I have seen destroyed, they didn't have enough heat or energy to do anything more than give a little smoke show. But then again, I don't DS and haven't seen what happens when one is involved in a 300+ MPH crash.

I would think it would be just as likely, (or not likely), to catch fire regardless of size. I only know of one incident where a lipo caught fire on the slope. The battery fell out of the e-glider somehow and landed on the road below. We don't know if it caught fire when it landed or if a car ran over it and started it burning.

When I was racing RC cars we had to use these things called "ROAR approved lipos". Lipos allegedly built to mitigate risk of a lipo fire mostly by use of hardcase.

Nothing saying you couldn't use a ROAR approved lipo pack in a glider.

Problem is, most of those hard cased packs are really heavy.

Everybody blames the lipo. In reference to e sailplanes, I think you will find that it's a failed esc that's more likely to cause a fire.

ESC's are the reason for every single fire I have witnessed in person. No ESC's in a sloper though. My brother and I have crashed the hell out of some foam slopers and done some major damage to batteries but we haven't had a fire or even a smoke show yet.

Radian testbed version 3


Here are pics of my version 3 setup on the good ole Radian.

Runcam Swift 2, Fatshark Pan & Tilt (roll servo removed for weight savings), Tramp HV running at 25mW, Pagoda antenna.

It works really well!

Nice-just like being in the plane.
I didn't realise that slope was so high until I saw those people at the bottom.
