and another burned up Schulze
 

This time caught on video.

http://www.youtube.com/watch?v=GrmTJEq3hNk

A guy driving a Maxx with schulze 18.97KW, plettenberg Maxximum and 5s2p A123.

I just feel sad for him. This was a powerfull setup.

It sucks.. I'd like to know what went wrong, seems like the crash had something to do with the melt down.

That was my first impression too. Maybe some electronic component of the schulze went bad after the last impacts and this caused a short.

The owner himself thinks that maybe the foam on which the esc was installed ignited spontaneously due to the very hot schulze ... but i don't think so.

On his previous runs he had some heat related issues with his schulze. It thermaled but never caught fire or smoked (obviously).

Oh Well ... i think this can only be sorted out by schulze. But personaly i wouldn't send this controller back to Schulze. They for sure would see an error made by the user and offer a small discount when buying another schulze. I would rather invest my money in another ESC (Monster Pro, Jazz 80 ...).

we all know the answer..

loose contact..

can you ask him for a picture for my gallery?

Seems you had the same experience? Loose contact. Was this the answer from schulzes support when you send yours in? What happened?

Sorry ... can't remember exactly how many stories i already red about smoked schulzes.

About the pic ... I'll ask another member in the german forum who seems to be in touch with him

man...........
 

i just got talked into buying a neu motor for my schulze controller, is there anything that can be done to prevent premature failure i'm afraid to use it

Well

. Make sure every electric connection is properly insulated and cannot easely come loose
. Try to mount your ESC so that shocks are not directly transfered to your ESC
. on your maiden run constantly check the temperature of your ESC and your motor ... If the ESC/Motor gets to hot ... change your gearing accordingly
. If your ESC/motor still gets to hot you can mount a small fan or heat sink on your esc/motor
. Check the temperature of your connectors too (Batteries -> ESC)

A monitoring device like the eagletree Micropower could be usefull to check your AMP requirements and see if you're overstressing your ESC. But this is not absolutely necessary. It can help understanding that every small change can affect Amp draw more or less seriously (Mounting bigger tyres for example has a huge impact).

but _paralyzed_ dont worry too much ... I think if you do not overstress your ESC it wont happen ... The circumstances as to why that happened in this video are not obvious and it shouldn't happen normaly ... There are other threads about smoked Mamba Maxxes, MGMs and so on ...

Those are pics from where the ESC was mounted in his truck after this incident

Sorry no pics of the ESC yet

They should put a a sticker on these controllers.

Here is my wall of shame.

And they should come with mini fire-extinguishers. :)

wow
thats a lot of ruined schulze's
and some destroyed when used with feigao's
suprising huh

Nice video bro... you should definately send the catching fire part to Schulze.. my 18.129 went to them 4 time already.. each time I recieved it, it lasted shorter and shorter...

instead of a Lipo saver sac, they need a schulze sac.. :)

maybe someone should have started a wall of "shame" for every brand of esc years ago. how nice.
anyway those 3.5mm plugs to the motor are very sensible. i know of some people who just soldered the cables for the motor directly in the bushings. so there is no possiblity for loose contact again. of course that voids warranty. but there isn't any warranty anyway so who cares. :-)

did you have temp shut downs of the controller with this setup before the smoking situation? its a very hot setup. i guess its very much on the limit for the 18.97kw.

rhylsader;

I collected pics of smoked BK controllers for a while, but they look less spectacular, and it simple takes longer before you have a collection that's near as big as the schulze.

Feel free to post me any pics though, i had pics of 12 burned schulzes and 2 smoked 9920's Both 9920's where replaced (back in the days when bk knew what service was) 1 of the schulzes was replaced, but ofcourse, with a 25 or 35 euro investigation cost..

Serum,

it used to be in the rc boating world, Castle B-80's and B-125's were the noted smoke bombs of the day...

truth be told, i emagine 90% plus of esc failures are user error related!

it's crystal clear you have a problem with Schulze
controls and wave it around in public like you're on a mission of sorts and that's fine...

personally i like my Schulze controls and chargers!

and in three years of [on the edge] rc boating [high amp] applications i haven't had a failure to date!

and i've found thier service as good as one could expect being on the other side of the big pond...

email tech support is usually same or next day...

the turn around time and costs of up-dating my controls and chargers hasn't been all that bad eighter...

to each his or her own :010: it's a matter of personal tastes i suppose...

Regards,

W. Ron Green

Well Ron, i have got all reasons to do so, since i was told at the most arrogant way that i made an error, an error in my choice of plugs, these plugs where adviced by them to use, i asked them by email if the plugs i used where okay, which where okay according to them, later i heard i could buy a new 1897 with a too good to be true 25 percent discount..

After about 20 emails going back and forth (he even tried accused me of machining the plugs) he decided i could have one for free, since he admitted i used the plugs he advised me. it still had a ~35 euro 'investigation' costs..

Rock on..

If you call it a matter of personal taste if i don't like being treated that way, I don't get that? I am on the mission of helping people take a setup that is durable and not being backed up with the worst service in the world.

So yeah, keep away from schulze, that's my advice and i am not the only person on this world/forum who has got a bad experience with their service so i guess it's not an isolated case either.

You have got good experiences with schulze because you haven't burned one. You never needed their dark side called 'service' or 'warrantee' i only know of 1 case in which the controller was replaced for free.

Castle has been nice and good to me. i smoked 2 controllers, one was a weird programming issue, it was replaced within 4 business days, the other was my own misstake and was replaced in 3 business days for 25 bucks, including shipping. That's the service you need with controllers..

I am not saying anything wrong about the schulze chargers.

got me talking about schulze makes me realize that i recently smoked a receiver of schulze (the Berg thingy) it was 2 months old, ofcourse i needed to pay for the repair.. 15 or 20 euro for something that should be warranteed. channel 2 stopped working.

Sorry, but don't get me started about schulze.

Boats are a complete different load for the controllers than our trucks are. Appearantly schulze hasn't got it all figured out yet.

They make smooth controllers for a relative high price, but their service is the joke of the year.

Their support is more than okay; they answer emails on sunday as well, but don't come to them with a smoked product..

hi

just to make it clear. i am not a schulze fan boy. the only thing i am stating is that i doubt that schulze controllers fail on systematically basis more often than other esc. but as there is no way to proof that or the contrary. so we have to leave it at subjective experience which is usually mixed. empirical data on this is simply missing and some posts in forums are of course not a reliable data basis.

anyway. back to topic. i would recommend to send the esc to schulze and see what happens. as there is quite a high probabillity that they offer you a new one with 35% discount you either buy a 18.97 again. then i would either reduce voltage to 4s or put a bigger fan on the esc or try to watercool it.
otherwise i would probably go with a quark monster pro as this esc works great with the plettenberg. you have to put some fans on this esc too.

are the mgm actually working with the plettenbergs?

MGM claims to work with any motor available and the list plettys in supported motor list

thats wrong approach cooling ESC to help it survive the load. You should use ESC that can handle the load with just heatsinks

The problem I see is that schulze does not mention anything about not using their controllers in heavy trucks like Sky Technology says about Quark. i knew that i can have some issues in my heavy maxx so i moded my quark and now I am happy

Schulze ESC are very expensive and they should perform accordingly

Yeah, the MGM work with the pletties, Don't get me wrong; i do like the smoothness of the schulzes, but there are smoother controllers available (such as the quarks) it's not the functionality that's got a big questionmark on it.

The new MGM controllers have got an onboard BEC (switching type) are capable of 120A continues, programming card option, and only cost 180 euro.

not bad considering they are a 6S with LVC and UBEC integrated. :)

nice to know the mgm work with the pletties.

however concerning the smoothness i have somewhat different experience. comparing the monster pro with a plettenberg maxximum and the 18.97 with the same motor in the same car the latter was noticeable smoother at very low rpm. not that i would matter for bashing. :-)
