does it smoke only on 3s?

TheKennyKiller

that sucks that the esc on these is crap but rather then stocking up on crap why don't you look at getting an ESC that works like it should, people have mentioned trying the mumba max pro but you might need to add a deans connector. It can't be much fun using your truck wondering when it is due to die next. or you could just take your XS to a disco and use it as a smoke machine.

I only used 2S and not dare using 3S
2S dead, 3S smoke

I seriously wonder what the issue is with the ESC's. I have been running mine on 2s and very limited on 3s and have had no issues.

Foxy

In all honesty, I'd have to consider looking elsewhere for the problem, if you've gone through two new escs with exactly the same issue. Just a suggestion. If I were HPI, I would ask you to send the whole car and your batteries in if you killed 2 escs like that.

I'm not saying it's your problem, or your fault, just to consider the possibility.

dcfever

I was going to send all the electronic related stuff to HPI just to make sure, but they told me only send them the ESC, nothing else.
Sounds like they very sure is the ESC problem
the battery I was using is Silverback 2s 5200mh 40c and 5600 50C. they are new and I pretty sure they are good, also the motor is running ok
then I asked what happen to mine last time, they didn't say anything

chopan84

will this battery work? looks like it will but wanna make sure

What is the firmware version on your ESC?

Foxy

That's a good indication on its own that HPI knows there is a problem with this ESC. Hm...

Zoocity

Sorry, won't know until two weekd from now.

Hey Foxy, did you smoke your ESC?

redfisher1974

When I called about my ESC they did not sound surprised at all, Did not ask for receipt or anything..Just send it in they said.

Took my XS to the skatepark today for it's second pack and first real bashing. Aside from scratching the body like crazy and scuffing everything up, I also managed to blow off the front right hub/wheel (my fault). I clipped a wall at a pretty decent speed and parts just went flying. I'm glad that I was able to find those 2 little metal pins so I could reassemble it! It'll work fine for now but the hub is cracked so I'll buy a new one when they become available. I'm pretty impressed with this truck for now, the durability is awesome! That being said, the steering is super sloppy and it makes the truck very hard to control. The truck pulls whichever way it wants. My front wheels aren't even parallel, they have way too much toe out and it isn't even adjustable! Anyone get this thing to track properly?

Foxy

I don't have one yet, but I will sooner or later.

I think they plainly undersized the ESC in this thing. I just got done run if mine on a 5000 2s 40c, the temps were 140 on the ESC, 170 on the motor and the battery was 110. I noticed the wiring was hot to the touch, I checked that and it was 135. Does any one have a current logger that they could use to see what kind of current this shrek is pulling in this heavy truck?

I'm sure gearing down would help and so would dropping a lower kV motor in it. Or say screw it and run MMPs like some of you already are.

Hopefully HPI catches on to all of this rather than selling a product that isn't worthy!!

hot but not hot enough to damage..??
your battery is 40c but your seeing 110* temps?
how far are you runing you pack down to?
I run 30 to 50c packs in my boats (they bull more constant amps that this little guy) and my packs come back 100-110*

dcfever

where I can find out what firmware version on ESC ?

dcfever

I gave them 2 reference now, hope they can figure out and solve it please

You would need the Castle Link to see what firmware is on the ESC.

dcfever

same here, mine is second time already. nothing asked or answered, just send back that's all

I feel sad to wait another 2 weeks to play again , not so enjoy now

Spaz163

I will run the pack until it just about hits the cutoff, you can tell when the power drops off significantly. That 110f was at the hottest spot on the pack also, the rest of it was cooler (more like 105) but still hot enough. Hopefully someone will have a current logger and we can see if current spikes is what is killing this ESC.

just something to try....
next time see what your temps are when you don't run the pack to the cut off....
thanks for getting back to that question!
some packs and electronics get hotter when they are run to the cut off

cooper998

four packs through and it flamed up! was running 3s Venom 5000 20c pack and motor and esc were getting very hot. Talked with the guys at the lhs and they suggested gearing down but did not have a smaller pinion at the time. My guess is HPI geared it to run 65mph so it could claim the top speed and would try to correct issues as they surfaced.
Unfortunately we suffer as guinea pigs while they get their act together, which I am sure they will.

Anyone know of a reliable esc I can use while I wait for a replacement? Will the Sidewinder Sv2 be good enough?

You should be running a lipo with a "C" rating of 25 or higher.
