RX8 on fire - RC-Monster Forums

Maybe it`s april fools from tekin?

3-4min ride in snow.. my castle 1515 wasnt even warmed up yet..
Stopped, smoked, and before i got to the car, it flamed up. But i ripped the lid and disconnected the lipos right away.
Lipos was probably saved because of soldering pins that came loose from the esc.

I`ve had a heavy portion of bad luck this month.

Just maybe the soldering pins were coming loose before the fire and actually caused the problem in the first place? It could have been from one of the pins shorting out to another pin or something else in the mix. Sorry to read and see your bad luck, but ya know what they say. Once you hit bottom there is only one way to go from there, and that is UP... Better luck for the rest of 2011.

It might be so.. Guess i`ll never know.

Now i`m really wondering what ESC to get next.. I`m buying one new for my e-revo, and one for a truggy project..

Even as i hate the cogging i have on my flux with MMM 1.29, i must say i do love the auto lipo function. And since i`m buying 2 esc`s, thats over 60 bucks more for RX8`s.

If i where racing, the RX8 probably would get my money, for smoothness.
The sensor part is nice, but not needed.
One thing i REALLY liked though, was the led`s showing temps..

Well, i got a $1000 order waiting to hit "buy now" on tower (thank god for the member discount), with 2 MMM`s along with a truggy ++, so lets hope i`m done having bad luck for now.
It`s getting expensive.

Well at least you have $1000 to spend on R/C in these tough times.

It just seems like things keep poping up one after another in somewhat manditory expenses.

In fact I don't think that I have ever spent that much at one time on any of our R/C colletion.

I know for sure that I have never dropped that much in one shot at TH.

Must be nice.

Prices here in norway is crazy, so we are paying around 1100 bucks just for a E-revo BL over here with all the taxes.. So that order on Tower was a bargain compared to our LHS haha

But it`s alot of money.
I just sold the fat pig (flux), so it`s not just savings though..

If it got wet that can also be part of the issue. The Rx8 is not "water proof".

Ola · 04.18.2011, 05:55 PM

Nope.. I use a outerwear cover (all chassie type), and everything was bone dry inside the cover.

TekinTeamMgr · 04.18.2011, 05:56 PM

Curious, what lipos? How many cells? Brand?

Ola · 04.18.2011, 06:03 PM

Turnigy Nanotech 6000mah 25C constant, 50C burst, EC5 plugs..
I was running 5s (3s + 2s in series) at the time, on 42mph gearing.

The batterys has never ever been slighty hot after running them, and they both where 3.98V pr cell after this happened.

Ola · 04.18.2011, 06:05 PM

Oh yeah, normally when driving it, the esc showed mid temps on the LED`s..

TekinTeamMgr · 04.18.2011, 06:36 PM

Ideally we prefer to see 30c cells minimum. Low cell discharge can create a large ripple current spikes that can over work the systems and cause a failure. I of course can't say this was the case in your situation without seeing the unit first.

next time you should buy the 4000mah 30c, can take alot higher amp draw(becouse of higher c rating) and even better its cheaper.

6000mah 25c lipos are 150 amps, more than enough, IMO.

Actually that would be less than the batteries he was using, it would only be 120 amps

Remember C rating is not everything!

Thanks, thats my opinion exactly.
