dont buy this crap it sets on fire burns out your truck and you get no help. only told to send the esc and motor back. and jumped to conclusions about my batteries before they even know what batteries im using. they say use over 4000 mah and 30c. mine are 6000mah and 100c. laughing about this and never buying rc rubbish again. goin back to real sized motorcycling it was cheaper and less fires! it was fun while it lasted though but after spending over 900 quid it was just a massive waste. castle suck.

Sorry to hear that.
I own to castle sets (mamba monster esc and motor)
never had an issue and one set runs on 20c 5400 mah batteries.
But that wont help you I know that :-(
Good luck with what ever you decide
dude I told not to believe the specs on those batteries.
But all is not lost, the Erbe is still a fantastic truck, you can probably sell it for a decent price.
i know guys, i love the truck to bits and it put me on a proper downer when it happened. i am sending the motor and esc back to castle to see if its a warranty claim, but if not then god knows what i'm gonna do, all the options are expensive lol. it didnt kill my batteries though, thats what i dont understand, the esc is melted it was running for 2 mins at walking pace. it de soldered the esc wires but the batteries are fine. the motor also was stiff and wouldnt turn but got badly burned from the esc fire.
It really sounds like a case of ripple current. I'd suggest adding some capacitors if you're going to stick with those batteries.
Oddly running at slow speed can be very hard on the ESC, it has to switch the fets on for just a moment in time, as opposed to WOT where the FETS can actually switch fewer times and be left open.
just checked my batts, it didnt even flatten them. all 6 cells still registering 4.00volts each, and stiil at 5000mah after the fire(it used a little power from them but thats all). all charged still and balanced perfectly. is it still my batts as i've used these all the time with no issues so far.
Just because the battery voltage is ~4v doesn't mean they don't have high IR, which would increase ripple current. Not saying that's the cause, just that you can't draw conclusions from a simple voltage check.
While it is highly unfortunate that this happened, I think it was either a battery issue, a loose connector somewhere, or simply an ESC fault.
People fail to comprehend the amount of current these little ESCs control. These things regulate/control hundreds of amps! There is nothing else on this planet (barring military grade devices) that will do what these do for their size. If you look at any other similar device, you will see they are much larger/beefier, but ESCs have to be light and small to fit on models. Shrinking things down tends to make them fail spectacularly when they do fail. I guarantee that if you were to find a suitable ESC for your 1:1 motorcycle, the device would be much larger watt for watt.
Your batteries are likely undamaged, but could still be the culprit.
The ESC is just a high speed switch, it opens and closes the circuit to the motor, usually about 13,000 times a second.
Problem is batteries are just a lump of chemicals, it takes a reaction to get the juice flowing, and that takes time... longer than 1/13000th of a second.
This is where a capacitor comes in. They can charge and discharge dang near instantly. Think of a flash bulb, thats a capacitor discharging through a bulb.
The capacitor in effect allows your battery to discharge as instantly as the ESC is wanting....
But if they can't, its the ESC that takes the hit. Your batteries don't care, the actual amp load was probably never really high.
edit: (if your esc is toast, get those batteries in storage mode!)

When a load is placed on a battery, the voltage sags a little. When the load is removed, the battery voltage rises again.
The amount of voltage sag is determined by the battery's internal resistance (as well as any connector/wire resistances), and current draw. If a 12v battery has an IR of 0.01Ω and 50A is being drawn, the voltage will sag to 11.5v (12v - (0.01Ω * 50A).
Since the "load" is switching ~13,000/sec, this a series of "ripples" as the battery voltage sags and raises accordingly. FETs don't like these ripples, so this is what those caps have to filter out. But since we are drawing high currents, the caps are working harder to keep up.
Better batteries have lower IR, so there is less voltage ripple. Adding caps helps to share the work on the existing ones.
That sucks nobody will do anything about it. I feel ya Frostbite man. I can't blame your lipos yet. Maybe something happened the driving session before The Final Voyage. Can you take us back to then? Tell us how that went. How long did you run it? What pinion and spur? Did it hit the LVC? What's your Lvc set at? What's a Lvc? Was there large amounts of moisture involved? Any major wrecks? Motor temperatures? Lipo temperatures?
My Condolences for your loss.
it ran for an hour and a half the time before, ran cool i felt the batts motor esc. stock gearing wheels tires and everything. no bad wrecks neither thats what i dont understand. but if it is my batteries then i made a real expensive school boy error. lol is it worth sending the esc and motor back or should i just go on ebay and buy a set? it would be quicker and easier. and buy some traxxas lipos this time just in case. what do you think guys?
Hasn't Castle been recalling a lot of their ESCs due to fires?
I would definitely send the ESC/Motor back to Castle. In all likelihood, they are going to replace them under warranty.
For sure send it back.
Also, this is your first rc right? Or at least your relatively new?
Maybe try less than 6s for a while....
no mate ive been in the hobby since i was 5, now i'm 28 lol but its the first castle system i've had. i had the merv vxl for about a year on the same brand lipos and i have 7 rc planes that are lipo and helicopters boats and rc brushless bikes the venom vmx, i have quite a collection.
oh all my stuff is brushless as well.

Just about 55,000 HV ice controllers were recalled LaTuFu. A replacement might take awhile to get back because they say they are really busy. What do you got to loose with sending it in? It's a long shot but, maybe your hobby store can trade you out for a new ESC if you purchased your revo recently?
thanks for all the help everyone. hopefully i will have it running again soon. i have read a couple of threads on here where people have had fires with the system. i have also seen a vid on youtube of a speed run and a fire, the revo then spears off into a hedge. he had the v2 same sytem as me apparently. i will write and let you all know what happens and the diagnosis from castle.
What esc/motor combo were you running at the time of the conflagration?
the stock mamba monster brushless esc and 2200kv motor combo that comes with the 5608 e revo brushless edition.
Send er back, the same exact thing happened to me, only it happened 3 times to me, and i just keep sending the ESC back. No cost to me as the speed controller has a year warranty. Never the motor though mine has always been fine.
ah, my motor has freed off now, it was very stiff after the fire, but i'm wondering if it was the capacitors discharging what they had left in them? iu think i'm gonna send my motor back though as is is all burned from whatever came out the esc. thanks info!!
Good luck and hopefully you get a new motor/ESC back and will be back here in the forum :-) to tell about it
no problem guys i will keep you informed. today i phoned the shop where i got the truck from and they are going to sort it all out hopefully. this time i think i may purchase the ******* **** tech 6000mah 25-50c lipos they're not a bad price on ebay. any of you guys run these batts and know if its a good choice or not? thanks again everyone, what would i do without ya!!

Don't expect a fast replacement. I sent my system back to castle 5 weeks ago and still no replacement. They are having a big recall on some heli stuff but that's not my concern. I want my system back. Thankfully I have a nitro revo that's rock solid. Disappointed with castle to be honest. Won't buy another system of theirs.

I could be wrong, JMHO I think most smoked ESC & motor failures are operator Error. Wrong gearing, poor quality batts, got it wet etc..etc... I am sure there are some that just die... Just think how much power is going thru the ESC, & the hostile environment they have to work in. Just my 3 cents..
Would you go flip my truck back over??
I suspect you are correct, as you say though some just pack in. Mine died despite it being pretty standard and very well looked after. I don't mind things breaking, it happens but weeks and weeks is just a joke.

oh and by cheap lipos i used i mean the ones you usually get free with things, when i buy a lipo i try to get a decent brand if i can help it.
oh yea one more thing guys, i asked castle by email which would be the best batteries for the mamba monster esc and motor about 4 days ago and still they wont reply. but they answered my other questions strangely.. i'm starting to think its nonsense about the lipos and just a fault.
Sorry to hear that. It's entirely possible that CC is making that statement due to the wide range of "standards" used by various battery companies for their C ratings. One company's 25C is another company's 30C, or worse, 20C.
25C can work, and there are many members on here who will tell you it works just fine. Traxxas' own proprietary batteries are 25C. But buying a 30C battery will work just as well, and will possibly work better, at least for the battery's life cycle, if not the esc and motor as well.
I bought these for my Summit but I've been using them just as much in my ERBE lately, can't recommend them highly enough (and very glad some SPC fans on here turned me on to them):
