Lol...

I have burnt 3 Schluze ESC and had spent or wasted over a thousand dollars but never had burnt esc from MGM,MM and Quark.

I will do what Mr. Schulze asked me to do and take it from there. The first video with the Mega, I didn't have any issues. Do you guys think do to the truck rolling backwards had something to do with what happened? I never had anything like this happen to me before.

Let me know if this are good for Mr. Schulze.

The length of the cable from your batterie(s) is missing on your pictures.

This is from the manual i found on their website (translated from german):

. cable length to your motor should be 10cm
. The length to the batterie should never exceed 20cm
-> Exception: Schulze 18.97KWF (max 30cm)

If your cable length do exceed those values, then you must add low ESR capacitors to the ESC.

Hope this helps.

Mr. Schulze only asked for those though. I sent him an e-mail with the photos and I will wait and see what he'll say. If he does ask for a picture of the battery, I will take some. Thank you for the input othello.

I think he can recognize a smoked controller on those pics. it should be obvious. The ruler is in inches? (oo,)

You guys were right. Mr. Schulze basically said that I was using power cables that are 4 times the allowed length. Funny thing is that in the instructions the max length is 8" and 4 times that would be 32" and I don't think I have or would be able to stuff 32" of wires in my truck. Look at the vide and tell me what you guys think: http://www.youtube.com/watch?v=EAtcnCTdjAI. That doesn't look like 32" to me. I've seen people use longer wires than I did and I used the same length wires with other ESC and nothing went wrong. He also said, "A new controller would also fail within minutes or even seconds". We BS to that as the Schulze 18.97 ran fine for a few runs and the only thing that might have caused the fire, was when it rolled backwards and I tapped the throttle and poof. Also, BS again to what he said as I'm now using the much smaller 18.61 with no issue yet and to make things interesting, it's the older version of the 18.61 with 2 capacitors instead of the new version that have 4. So there you have, IT'S MY FAULT!!!!

What's new?..I've had that BS from schulze quite a few times as well..... When it comes to Customer service warranty and repair... Schulze just suck Monkey Ballz..

Good thing I don't live in Germany. I would be knocking on Schulze's door for sure.

I'm still waiting for my 18.129 to come in... I bet I'll be paying half the retail cost for repair... I wonder what excuse they're going to have this time.. this is probably the 6th or 7th time it's been there....

Wow. Schulze needs to step up it's customer service, specially with the new controllers that are coming out.

I am not playing devils advocate but looking at the video you just linked I wonder were you trying to make a flux capacitor ?

I mean whilst its not quite 4 times the max length (I think they were exaggerating) your battery cables are way to long and looking at the way they loop around and remember that you have to add the cables in series to get the total effective length.

Put it like this the series link between the packs alone in that video looks to be about 8-10 inches then add another 8-10 for the rest of the y cable then add another 8 inches for the cable to go through your eagle tree and back to the esc.
That adds up to a lot of cable and inductance that needs greater capacitance for decoupling.

I will add that schulze seem to do everything in extremes that includes escs failing in a ball of fire and treating there customers like they questioned there parentage.

The length of the pack cables are 5 inches, the series adapter is 5-1/2, but I've use the same series cable for a long time now on other controllers and nothing happen to them. I used the Schulze more than enough times and Mr. Schulze said, "A new controller would also fail within minutes or even seconds", which is BS. I have controllers that even states if I shorten any wires, it would void warranty. I'll see how long the 18.61 will last. The MGM controller didn't have any problems with the wire length and it ran cool just like the Schulze was running before it flamed up. You should see the length of the Spin 200 wires and I've seen a guy in rcgroups using the Spin 300 and the length of the wires are even longer then what I have. Here is a link of an even longer wire: http://www.rcgroups.com/forums/showp...2&postcount=52, good thing this guy is not using a Schulze controller.

Sorry to read this. I sort of expected this outcome when he asked you for pictures of your setup. Cable length: It really depreciates the value of their high priced ESCs. I measured the cable length i use in my car and came to the conclusion i never could use Schulzes as i do exceed their max allowed cable length (38cm/15in in one direction -> 80cm/31.5in when adding the plus and minus cable). Using 2 packs wired in series and an eagletree adds quickly. Never thought my total cable length (when adding motor cables too) totals 1m/39.4in. Glad the Jazz ESC never complains about it, but it explains my voltage drops on high amp spikes.

Thank you for posting this othello. I know it has nothing to do with the wires being too long, because I've used the same series adapter on my other controllers. Some controllers that I have, the length alone of their power wires is close 10 inches. I think they might have a flaw in some controllers that do come out of the assembly line that got passed by QC.

hi

how old was this controller when it burned up?

btw i once tested this backward rolling and full throttle thing in the maxx with a schulze 18.97kw. the truck stopped for a split of second before it went forward again. so i think its not going directly from backwards rolling into a forward motion.

what exactly is the 'common wisdom' why the esc fried?

bye

The controller was made in 04. What my truck was rolling backswards slightly after a slide and I gave some throttle it did stop, but that's when the controller started catching on fire. Schulze can say it was because of the wire length all he wants, but that's not why it fried.

Schulze has the best thermal protection... right after it smokes up... I hate them guys, but their controllers are so smooth (when it's working)..

I was loving the 18.97. Now I'm loving the 18.61 and I hope it can lst longer and what will Mr. Schulze say about that? :lol:

Yes lutach that guy is also using a very long wires but in an airoplane your much less likely to get spikes of back emf from the motor when you try to drive it in a direction that it was not intended.

I think the problem was a combination of using a motor that probably generates a lot of back emf (I doubt schulze test mega usa motors) and your wiring loom being so long add to that the fact your running through a eagletree device that probably adds quite a bit of inductance itself.

Needless to say if i were you running a big ass cap as close to your 18.61 as possible should help protect the esc from these transients that the mega is probably generating.

I would also say looking at the wiring you could easily reduce the length of your wires by half and still have slack.

The highest spikes from when the 18.97 failed was close to 75A. I'll see if the 18.61 can last long enough to give MGM time to fix all the bugs with their controllers. It would be strange if the 18.61 does last longer.

did you try the newer hacker controllers on higher cell counts?

I noticed that someone said they were using like 5s on the old hacker master controllers but a couple of years ago when i tried to run 3s lipo on my hacker master race if the voltage was over 12.3 ish it would not arm. I wonder if perhaps using a ubec would enable this controller to function on higher voltages.

I haven't tried my Hacker Master Race yet. I will wait for MGM to fix all the bugs. I might look into one of the new Schulze controllers that uses the D2PAK MOSFETs. My 40.160 is great and I'm sure the new controllers would be good as well. Who knows, maybe the guy who is doing my controllers would answer my e-mails and tell me they are done. I hope he doesn't run away with my MOSFETs.
