Kraton 8s Bash with XLX2 Fire Chat 

LoL that darn nut!!

I haven’t had those issues

Firmware can definitely have an effect on efficiency and amp spikes. A high pwm will cause the gate drivers to enter a state of neither open nor closed more often. This halfway open state is where mosfets generate most of their heat. Even someting as simple as punch settings can drop those amp spikes that pop the esc internals.

How would it be tuning software? You could not even download the software and it could probably pop

Sorry about late comment on old thread. I'm on my 2nd Xlx2 which was a brand new warranty replacement from castle. 2nd run it burst into flames, burnt both turbo fans, shorted both my lipos and nearly burnt my body off. I was told bad solder joint but an electrical engineer that works with me soldered every joint. Qs8 anti spark connectors....the works. It smoked every connector, component on my power system. Fed up I bought a Ztw 12s Beast Pro. Never been happier. I run 3 4s in series.......perfection. 800kv castle. Buttery smooth....6 months no issues.

LoL the phone picks that noise up way more than it is in person

It’s not so bad at all in person but the camera pics it up way too much.

Mostly think of water, and what creates water pressure or more accurately a high amount of water current to flow. to increase in a pipe. Electricity is kind of similar as far as things breaking, except for the whole pressure thing. Gravity can pull water down hill, so maybe the old analogy holds up...

Right. I see the burnt up esc’s but in most cases the plugs are fine. Even the xt90 ones. Now the DBXLE2.0 is the only one I have where I have noticed a bit of heat at the plugs so that one needs the 8mm plugs soon.

@@ExocagedRC remember copper wires transfer heat as well as electricity. Large wires can wick away much of the heat and save the plug. That and the short in the esc is not necessarily perminanent. So the short in the esc can fail before the battery plug, but after the battery has already reached thermal runaway. Also a lose plug conection can generate more heat then a good tight conection. Think of the conection as surface area and spreading out weight, but in this case its heat. Also the plastics have different melting temperatures that vary from manufacturer to manufacturer.

Something else to consider is the amp ratings. Which esc manufactures dont share. These are more of a hard limit then sharing recomended motor kv limits. Constant amp ratings are say 100a, but every 10 seconds you throw a 200a burst at the esc, this just raised your constant amp draw as well. This translates to more heat in the esc then it can handle. I dont know the ratings for the esc in question, but my guess is a 600a burst exceeds the recomended amp draw. Talking about getting bigger batteries that supplies more amps just increases the probability of catastrophic consequences. Setting the punch down one step to 90% will prevent the amp spikes quite a bit. And most likley eliminate the problem. But everyone wants to push it to the limit, and some people find it sooner then others.

Ole Bobert is talking shit about stuff that he has zero knowledge of. Fires that make their own oxygen and loose plug surface area causing heat????? Jaysus. Dude. Go back to school, and this time, stay AWAKE in class.

LoL maybe!

Lmao

Castle insinuated he smoked it on purpose i felt that was really strange for a company to say but check out some of his other videos he runs his motors and esc's with to large of battery packs all the time

@@KZizFISHIN Large capacity Lipos is not an issue or reason IMHO. Not defending KT, But don't underestimate his knowledge of RC. His light hearted humor and antics does not mean he is ignorant with RC electrics. Not fair for Castle to discount KT's observation and his opinion in regards. Also Not the greatest fan of KT. Entertaining to some extent. Just being diplomatic in regards. Castle dropped the ball . Lets face it. All companies make lemons here and there. It's important to own up to it much better, respond quicker. Not blame user error all the time. Castle just got caught with their pants down in 2 of KT's videos. But if KT had no issues, those videos would have sold another 3k XLS's. Then Castle would be all good with that. Just didn't go that way did it? Not fair to bash KT. He didn't cause the 2 fires IMO. He just documented what happened. He is good at documenting footage. He does that well. Play by play. And Castle's product didn't look too good.

@@simp8017 I agree 💯... love him, or hate him(KT), the man generates views, which in turn could generate sales(or lack thereof) pending the outcome. It was unfair for a castle employee to put the blame on kev, but who knows if the person that commented was an actual employee? I'm all over the place with my reply... 🤣🤣

I agree probly allot of simulation more than real world

Thank you for that. I really appreciate it.

My mmx8s esc’s have been solid. But then again my xlx2 esc’s have been good so far.

@@ExocagedRC My MMX8S has been a solid preformer. My comment was a bit confusing now that I read it back. I think Castle has had some manufacturing issues with the XLX ESC's that went overseas 👍

One day. Would a live bash session be ok? Or a live crawl?

@@ExocagedRC Video quality is poor when you do those. And you know how important that is on here. But it’s up to you. Lol I think you would still get your same normal views tho. I just wouldn’t do them a lot. But doing them for discussions or something every so often would be ok. It wld Save ya the other bs work in it.

Thank you

He may have had one with the buss bar incorrectly installed.

To be honest that guy uses shit he finds in the alley

Kev kinda is a shinning example of what not to do.

No. Kev was running a 4300 kv tp motor. Too. None of that was his fault. Or anything he used in the car. Metal is metal idc where it comes from. All of the connections and wires comes from China anyways. Lol. It’s like my oL pap said. German parts ,American parts , ALL MADE IN CHINA 💁‍♂️. The only difference is the esc. The firmware isn’t adjusted for the higher amp draw of a 4300 kv motor.

I believe it's the 1100kv combo also that's why it's never available 🤔

LoL

I use deans on crawlers and xt90’s on big stuff.

@@ExocagedRC yea I have a terramoto10 v2 with a 2250kv 3674 in it on 4s I really wanna try a xt90 cuz it seems to have a really bad cogging issue even on the stock motor idk what else to try its got the hobbywing sc8 rtr 120a esc any idea on what i could try? The whole brushless is new to me years ago when I was in the hobby I had all nitro stuff cuz there was no brushless then lol. Any inside from you or anyone else would be greatly appreciated. Thanks Joe

Ahh ok. Great info on that. Thank you.

F/W fixes are usually a band-aid for H/W related defect issues. A bad run of Mosfets for example will get a F/W fix to limit output across that Mosfet. Still a band-Aid, which then circumvents the intended specs of the Mosfet application. Then there is even more with the Delta update. Castle advised not to run them with intended motors till the Update arrives. Guys have these ESC's sitting in boxes collecting dust waiting for the F/W for months now. That's not Castle love if you ask me. BTW, If KT was using a Delta wind motor, is it his fault the XLS2 burned??? Castles fault in my opinion. Maybe Castle ESC's just wont play nice with other branded motors to begin with. Only their own Made in China motors.

@@simp8017 Yeah. I agree. But they are people reading this who made videos kissing castles ass cuz they get to test (which I’m sure is free ) shit. (Cough cough RAZ SHIFRAN ) and to say things like you did will make him act like castle just made these esc’s and others to benefit us. And they will quit if people hold them to something as simple as a warranty 🙄. And it’s not the eas’s fault. And he’s been into RC’s for a couple months. (Other than when he was a kid & before he got a little attention on a RU-vid video) So he knows. 🙄. And he’s selling a RC speed run thing too. So he acts like he’s one of them. Instead of a person who spends their hard earned $ that they probably had to save & do without something else to get that $ for to buy that esc ,💁‍♂️. (He has two videos trying to make people feel guilty for using a warranty ..or it’s just because they don’t no wtf they are doing like him. And they solder their worse wrong or something. Because it’s not castles fault. 💁‍♂️🙄😂. And they will just go out of business doing everything they do just for us /the SPEED RUN GUYS 🙄. As if that market share is above 1% smh. You should go watch his 2 videos on it. But I know exactly what you are getting at. Lol. I see it just like you. It was just bad design and probably a corner cut on where they got their parts/misfits or production problems on it themselves . I just didn’t want to get into it like that. Lol. But yeah. You’re right. I just put it in a nicer way.

@@simp8017 I watched a bunch of guys burn up after clean runs. And out of the box just plugging them up to other factory setups on wiring & servos. And I know had ZERO ABUSE. But like I said. Go watch his (RAZ shifrans I think Hes a bit arrogant tbh it’s why I rather watch Joe’s stuff on things like this subject better ) videos & you’ll totally understand where a couple of people like him are coming from. They just want to keep their game going more than anything when it comes to listening to others. Not to say JOE HERE is one of those people. I just know a bunch of these makers of stuff we buy & other bigger RU-vid channels, watches & gets in Joe’s comments section. And joe is a good dude.

I did!! 😀

Ok. When I was getting the overload codes it was with a bigger 7200mah battery. The smaller 5000mah batteries didn’t give me this code.

@@ExocagedRC Castle knows what is going on with these things. If the overload code doesn't shut it down, it will fry. People must be disabling it, or the barn burners might have a crappy capacitor pool. Either way, there's only so much that the hardware can deal with if the firmware isn't backing it up. I know Castle wants us to control all the aspects of this thing, but disabling overload protection when cranking up the amp draw is stupid. That's why they said Kev burned his on purpose. It was obvious that he disabled it when he programmed it. It should be inherent that there should be some type of failsafe machine code that won't allow the hardware to be maxed out no matter what you program it for - but I guess Castle like seeing $250 mini flamethrowers.

LoL yeah. Should be good for the DBXLE2.0. Will have incredible punch though!

@@ExocagedRC yeah you certainly shouldn't have any amp supply issues. Haha. Plus I've heard those are real quality batteries. I'm a venom guy in my bashers.

Runs the 800kv better than the MMX8s.

They aren’t cheap to get. I believe most of the board is encapsulated for water resistance. I haven’t opened one up though.

@@ExocagedRC well from the video of Kevs you can hear a quick wine then pop. And from all the electronics I have blown up thru the years building random crap it sounded like that to me. I wish I could get his and tear it down!

Your trouble shooting method is flawed. lets say for example you have a functional mamba x and a brushless motor. But you forgot to tell the esc to run in brushless mode and it is set to brushed mode. Without safety precautions the ESC will produce non switching dc voltage. When you pull the trigger what happens? The once perfectly good motor heats up because that's what brushless motors do when they get DC non switching voltage. But the problem wasn't in the motor, or the esc, it's in the user....

Over simplified but... They are just different methods of connecting the wires in a motor. A Y wind would be kind of like doubling the motor turns, the current travels twice as far with twice the resistance as it goes through 2 coils. On a delta wind the current only travels through one coil. So delta winds will have half the resistance and twice the amp draw and a twice the KV. Less resistance, so more power, so more heat.

@@Voodoobrew101 thx that makes sense, so with double the resistance is that what could.cause the issue then

Great points. So the Q8 connectors lowered the temps?

@@ExocagedRC using them im guessing it helped with lowering the resistance of the amp draw from the batteries and by that it helps with the temperatures. Before the QS8 i could run my xmaxx and after 10 mins the fan would stay on until LVC, and u could feel the heat coming out from the system. Now i could be driving and jumping and it will come on for a few minutes then turn off and unless im really pushing it doimg speed runs back and forth the road it wont turn un. And at LVC the batteries, plugs, esc and even the motor are just warm and u can keep ur fingers on it. I dont have temperatures reading cuz my thermometer died

thats interesting for sure

Why? I have way more control in the right hand.

@@ExocagedRC than using two hands? Cmooooon bro lol

The phone picks up on the noises worse than they are. But some of it is the dogbones at the diffs getting worn and loose.

@@ExocagedRC ok thanks. Really just wondering what mine should or shouldnt sound like lol.

There is a link to their info in the description.

Yep sure did. If you scroll way back on the channel I have some videos of that.

Wonder if that’s part of the buss bar they mentioned?

Mine just shorted between B&C on the esc. Purchased in April 2022. Less than 10 packs through it in my k8s, XLX2 1100kv combo 29/39.

@@waffleman2010 Outcast 8s EXB same setup ran 3-4 times and on the 5th time out about 2-3mins into the run the truck went up in flames.
