I had same problem with 80amp from hw...i used it a while without problem, I moved timing to 0 and it cooked in 3 minutes...
I wanted to increase battery lasting...I think i'll never get less than std timing in future

Bingo.
Since i've changed timming to 0 my ezrun 80 started to act weird till it stop working :oops:
I believe there are to many people with same issues

I've sent this thread to HobbyWing support... I hope they release an updated firmware to solve this... otherwise I'll be seriously considering the MMMv3 or Tekin system.

Yes dun try

If they do release an updated firmware how would I update my 80A HW esc? I haven't noticed any usb ports or anything of that sort on it.

The Advanced Programming Box is supposed to have USB connectivity for updating firmware.

Advanced Programming Box

Anyone know if they have fixed this yet? I really want their 150A esc over a MMM for the price, but with the failures I'm seeing, I'm not too sure...

Also, i'm guessing timing is the only thing that does it? Or do I just not even mess with the stock settings?

Fubar....

they r fixing it, it's only the zero punch thingy the rest are ok

Hobbywing looks to be having some trouble. I wonder what's going on. Sometimes I think it pays to test and then test again and again to make sure a product is free of any defect. I know those 2 Speed Passion monkeys will be scratching their heads when their 4S 80A expensive version starts doing this when they are set a 0 degree timing.

:whistle:so i just hope that they will fix that.....melt a esc in less than 3 sec.....really weird.....my firend here had 2 150 amps unit and now he scared to run it...

Considering MMM is on v3, it's not like other ESCs don't have problems either. Albeit, perhaps the failure modes of the MMMs weren't as severe, but they still died and became useless to the owners.
It's definitely an issue, but an avoidable one if you don't set the timing to 0.

but isn't the MMM backed by CC? which i heard was quite good in CS. if something goes wrong with your hobby wing, do you send it back to china? At that point it might not even be worth it.

IF you build them, they will smoke. Looks like no one is safe. Couple weeks ago everyone was raving about how great the HW controllers were compared to the MMM. Now that they have actually sold a couple we are going to see some go bad. Sorry for your loss, but it seems like the MMM is still the best bet for reliability and support. You've got a handful of these things that have sold vs thousands of MMM at this point. We see 5 MMM go bad and everyone worries, but 5 out of thousands is not bad percentage wise. I hope they fix it though.

hi bro, mmmv3 still hv problems after 1 to 2 yrs production. Many ppl are still burning mmm till now?

Hw products are not too bad I started with their plane esc 100amps till now it's still in my CRT truck.

Yes we may hv burnt afew 150amp but once it's solved it will be a great product how often do u hv a esc that run abt 50 degrees after 30min run?

I gv up mmm becoz there's no reason y it burns n can be any reason. HW burnt becoz of software(this time) I intend to try again as I dun hv the budget to run tekin rx8. No one knows can rx8 last too?

Hw is cheaper, can program on d spot a bit big though. Other wise I hv no complain.

Just my tots:)
