Ziggy122 Posted June 1, 2016 Author Share Posted June 1, 2016 It did the same thing on the castle with traxxas or losi motor's i've got Swapping to losi as we speak Ziggy Quote Link to comment Share on other sites More sharing options...
Noj Posted June 1, 2016 Share Posted June 1, 2016 100A constant pack for a 120a esc?? Oh, and hobbyking esc's are a bit crap, in my experience. Quote Link to comment Share on other sites More sharing options...

I thought Hobbyking was alright lol maybe not? 100A maxed motor with a 120A Constant ESC (480Amp Burst) The esc in thoery shudda been perfectly happy with it.... 8 minutes ago, turok007 said: cogging issues will be a rubbish lipo or faulty motor or ESC. But as i said before a bad motor will destroy the ESC But the Suspect ""bad motor"" Ran perfectly fine for 5 1/2 packs If it was "bad" it'd be from the word go maybe the lipo is the issue? could be - but again why would appear to be faulty after 5 1/2 packs from last one? Eitherway - confirmed dead esc, losi motor's replicating same fault.... Ziggy Quote Link to comment Share on other sites More sharing options...
Noj Posted June 1, 2016 Share Posted June 1, 2016 If the motor is pulling 100a max, then a lipo that gives 100c constant is not adequate, as there is no head room allowance. A 120a esc should have a battery attached giving 140a constant, so as never to be working at full capacity. Quote Link to comment Share on other sites More sharing options...
evssv Posted June 1, 2016 Share Posted June 1, 2016 (edited) hobbywing...not king........I don't rate hobyking esc`s no more....there cheap for a reason imo.. Edited June 1, 2016 by evssv Quote Link to comment Share on other sites More sharing options...
dazp1976 Posted June 1, 2016 Share Posted June 1, 2016 (edited) Specs say it handles a 2-3s lipo so you're on the limit there. My guess is you've also got it geared high so you're on the limit with amps and voltage. No wonder it poofs. How hot does that battery get? As Noj said, you should be over the esc by at least 20% ie 4000mah 35c = 140 amps so esc isn't stressing it. Dump the xcar and get a Hobbywing 4s sc8 and be done with it. At least then you won't be on the voltage limit. Edited June 1, 2016 by dazp1976 1 Quote Link to comment Share on other sites More sharing options...

I've got my system running so the battery peaks at 45 celcius, motor 70, esc 50. That's as far as I'm willing to push. Been like that for a long time. My gut feeling is the 2-3s escs are not really liking 3s even tho the specs say yes. If you can fit it in I think you should try a 4s Hobbywing SC8 or similar. The SC8 is prob around the smallest footprint in terms of a 4s 120A capable esc. Unless someone else knows a smaller one. The SC8 states that with a 3s lipo attached motor kv should be below 4000kv so it will run your 3500 on 3s easy Now reading the specs of the SC8 I'm thinking the smaller 2-3s types may only be able to handle 3000kv ish with 3s which could be the problem. At or over the limit on volts and KV. I just spotted the Hobbywing Max 10 Quote Link to comment Share on other sites More sharing options...

I just spotted the Hobbywing Max 10 well im putting the Traxxas motor on shelf for a short while - and gonna run with the donor Losi 4700kvh, just because of the fact - its looking like the motor could be killing everything Why cant castle max the mamba max again - it was a cracking ESC Ziggy Quote Link to comment Share on other sites More sharing options...
