Go home Turnigy!!!

[Boaterguy]

so, my second t120 decided to blow on me today, I was running 3S and drawing way under 120A, it just died. brought it in and changed the caps since they looked puffed.
plugged it in and got nothing, so I plugged in a batt to the RX and the magic smoke came out. I can't complain, the turnigy smoke smells relatively good, or maybe u'm just getting used to it...

Unlucky, only thing that burns on me are castles.

[tiqueman]

I love my 120s. One of the most reliable ESCs I run. Running 4, 5 and 6S in several of them. And Id rather a $50 esc blow than a $200. Id say your still ahead of the game.

[Boaterguy]

I'm going with an SS 190-200 now, since i'm gtting one for my rigger, theyll share it.

[siberianhusky]

Never owned one but from what I've read about those HK SS esc's is that the 200 amps is the absolute maximum it should ever see, not much of a burst rating to them.
Is this the one you burnt out running your hydro in the pool? I remember that thread from a while ago.

Oh my. Good luck w that. I had two, my neighbor had one and another friend had one. Note the use of "had". They are junk. None lasted more than 3 mo. With well under 100a on all of them. Shoulda stuck w the t120 or gone to the 180...

[rc2266]

I submerged mine at least 4 times(maybe I should coat it), still running strong, but I think I will go with the t180's from now on, seems like a great esc

this is the one I bought to replace that one... ugh.
t180's are out of stock, who knows how long so, this is the next best thing, I'll get the air version since I have two t120 heat sinks now, hehe

[Boaterguy]

yeah, i wish..
I can't afford much right now, that's why I'm getting an SS
a CC HV 240 would be great, that's what I would get if I was spending money. oh well

[rc2266]

OSE shows 47 T180's in stock now

[Boaterguy]

still can't afford it, 100$ for an ESC on an old boat that wasn't built right is too much. the boat won't get an ESC right now, it'll just share one with the rigger, the rigger will get an SS, maybe i'll get two, just in case.

[tiqueman]

Boater, I got a deal for you. $20.00 I will send you a brand new in package SS200 I got from Fightercat racing. Its still in its packaging. It was the type in kit form that you have to install the heat sink and wrap it. It comes w/ everything you need.

Just opened packing so I could take a pic of all the components. PM me if your interested.

[Boaterguy]

In toronto for the weekend, i'll PM you later tonight or tomorrow.

[rc2266]

If u tun that down ur insane

[Boaterguy]

I'm not turning it down, I can't contact him at the moment so I will when I get home from toronto.

[tiqueman]

No worries. It will be here whenever your ready

Couple questions... How do you know you were pulling under 120a? What boat, motor, prop, etc is this in? What pack were you running, were the capable of supplying enough current for the motor?

When you plugged in the RX battery, did you pull the red wire from the ESC plug so you weren't feeding power back into the BEC side of the ESC?

These ESC's come highly reviewed and seem to take a lot of abuse, I find it very strange that you've blown two in such a short time period.

This I did not do, but there was no spark. when the battery was plugged in
I was running a turnigy 3S 4000mah 40C battery on a 3600KV supervee prop.
the battery radio and motor I know all were functioning properly.
the ESC did not heat up too much, that wasn't the problem.

[tiqueman]

Probably why your blowing escs. If run an rx pack, you have to dissable the bec by removing the red wire out of the plastic plug. Id say by feeding it two ways you blew them.

[Boaterguy]

I wasn't running an RX pack, that was just to test if a specific part of the ESC was broken, it was the first time it was run that way.

[wparsons]

You just said that it let out the magic smoke when you plugged in the RX pack... If you're running a receiver pack you have to pull the red wire out of the ESC plug to the receiver, it wouldn't spark if you left it in, but it would harm the ESC since you're feeding power the wrong way through the BEC circuit.

What happened before you plugged in the RX pack?

I'd say the 3600kv motor on 3s with a 40mm 3 blade prop is also a potential issue, that's a lot of RPM (45k unloaded) and a pretty big prop. If you pull enough current to blow it quickly it won't necessarily be warm or hot.

[Boaterguy]

It worked fine before, I ran the BEC on 3S with no RX pack, and one day it decided to die in the middle of the lake, the caps were puffed, they got replaced with bigger ones (35v 1000uf). even after that, there was not a spark when the batts got plugged in. so that's when I tried to put in an RX pack just to see what was going on, as soon as the smoke came the battery and ESC were unplugged from the RX

[wparsons]

Typically caps only die or puff if the packs aren't supply enough constant current, resulting in ripple currents and spikes. So either you were drawing more than 160a, or the batteries weren't happy supplying whatever the motor was drawing. I would bet you were pulling a lot more current than you thought with a 3600kv motor on 3s with the 40mm 3 blade prop.

Even if the ESC is dead, if the caps are soldered correctly it will still spark. The spark is from the caps charging up, not the ESC taking power.

[Boaterguy]

okay, well it didn't even with the new caps, they were soldered directly onto the battery wires and not the ports since I could not solder in that small area safely

[wparsons]

How were they soldered, correct polarity, in parallel or series?

[Boaterguy]

Parallel, proper polarity.

[TheShaughnessy]

I'd say the 3600kv motor on 3s with a 40mm 3 blade prop is also a potential issue, that's a lot of RPM (45k unloaded) and a pretty big prop. If you pull enough current to blow it quickly it won't necessarily be warm or hot.

i agree with that. less voltage to achieve more rpm is always gonna make the amps go up. I have 2 120s that see 100 amp peaks regularly and never come in warmer then 140 ish, generally much cooler then that. I think you might blame the motor and prop before the esc. Have you tried adding caps before the esc goes? I have added 2 extra to each of mine, no problems to date.

[Boaterguy]

It's okay, I'm done with turnigy, I'll try the SS series for a bit, but the hydro will share an ESC with my rigger for now.

[wparsons]

IMO, stay away from the SS series... They're a low budget lower quality ESC than the Turnigy line. If you're popping T120's, you'll blow the SS125a way faster.
