All that shade thrown at Hobbywing, but the Castles are the one's blowing up.

[@xibidit]

the castle "on/off switch" apparently have more than 100% power available to the motor, since there is "more top end speed" than with the hobby wing "on/off switch".

[@KacKLaPPeN23]

@@xibidit Nah, it's just that the over current protection in the HW units actually works and limits the power output in those scenarios while the Castle will happily keep on pushing past it's limits until it goes up in flames. Brushless ESC's also are a little more complex than an on/off switch...

[@xibidit]

@@KacKLaPPeN23 not really man, it's mosfets switching power on and off, and if there is over current protection it would go into limp mode. Connect the wrong motor and wrong battery the esc blows, if the unit is faulty it's usually a mosfet that blows and starts a chain reaction. Take a 45A esc and a 60A esc with the same motor and battery, they will have the same top speed but the 45A esc might blow first. Look at RCexplained's channel if you want technical stuff...

[@KacKLaPPeN23]

​@@xibidit I've personally had some higher kv motors (above what the ESC was rated for) reach a lower max. RPM than a lower kv one with HW ESCs. Over current protection is the only sensible cause of this phenomenon I can come up with. If there was an internal RPM limit we'd see the same max RPM but that wasn't the case in my tests.

[@xibidit]

@@KacKLaPPeN23 higher KV motors have a lower resistance, probably in some kind of limp-mode since you had too low resistance through your windings. OCP usually cuts the power all together, but I can be wrong, there are some advanced on/off switches out there for sure :)

[@michaelregan427]

I don't think braking caused this. People run the kraton on 8s with big gears, big tires and the same power. The esc was defective IMO.

[@MZBallistic]

My thoughts exactly. My Outcast 8S is pushing 70 mph @ 30lbs with a MMX 8S zero issues.

[@AutoBodyEverything]

Awe don’t say that… I’ve seen these go up in flames… but I’m THIS CLOSE to buying a XL2 combo, …. They admitted 5% were defective but those defected ones go up in flames RIGHT AWAY! If you got as much as 5 minutes run time it “could” be something else….🙏

[@based_will]

My Outcast 8s EXB with the exact same system in it, fully loaded weighs 30lbs. I'm definitely not easy on the brakes, and the truck is geared high enough that it's hit 65mph. I think the issue here is a combination of belt resistance and a defective ESC.

[@Pascal_Robert--Rc_Creations]

Aint there a temperature cut off on that xlx2? Even with a monster car like that it should have cut off before it self-destruct, even from braking.

[@mikeupton5406]

Picked up my first above 1/10th tonight. A Limitless. Your a good influence ;). Been enjoying R/C since late 1980s. Does not make me an expert. But I know there will be trials and setbacks along the way. Let the butt kicking commence LOL!

[@alexandermcalpine]

I hope Castle gets in touch with you. Thanks for posting!

[@Motoinc]

The castle ESC have a known burn issue

[@samsmithmx11yamaha]

From my personal experience with motor drivers and controllers I believe something called back emf killed your esc basically when braking the esc cannot handle the high voltage and current flowing in the opposite direction from the motor back to the esc. obviously when braking the motor is working like a generator and due to the weight and inertia of this car it was to much for the esc to handle which by the looks of things has fried the diode in one of the mosfets and caused a shoot through on one of the half bridges giving you a dead short and obviously some flames, as a solution potentially adding a capacitor bank in parallel with the esc after the battery might prevent this from happening again you need a buffer between the batteries and esc especially when the batteries are fully charged make sure you use some pretty high voltage capacitors to handle the high voltage spikes

[@DoRC]

If you pretin the wire and the pre-fill the cavity in the connector with solder before you saw them together you spend a lot of less time at once putting heat into the connector making it much less likely to deform or melt it. I don't know if that's normally a problem with the QS8 connector but an xt90 would definitely start melting if heat was held on it that long at once.

[@KiloWattRC]

Has nothing to do with brakes. The FG is a baby compared to MCD. The esc was defective, luckily no one got hurt. There is a guy here in Maryland that hit 149mph with the FG running XLX2 and TP motor. Good content as always man

[@madmatt2769]

Maybe, but a gem of a car just deserves disc brakes! ESC is probably faulty though…

[@HighVoltageRC3080]

@@madmatt2769 I have two brushless FG's and both of them use motor braking. I'm running 8s on one and 12s on the other. xlx and an MGM esc powering the cars and neither one have caught on fire yet. Xlx2 was just faulty... thats all there is to it. We put the same 1100kv/xlx2 combo in another FG and its geared up for about 80mph, no issues in that car either.

[@RazShifrin]

@@HighVoltageRC3080 hey, i would love to see the xlx2/1100 in action so i can learn more, is there a video of it? Thanks!

[@madmatt2769]

Super interesting Raz! That beast can only have the best gear and as you pointed out a separate disc braking unit is a must. Can’t wait to see the next instalment!👍🏻

[@benhamer9125]

i considered an xlx2 for one build and passed it up as i didnt want to see £2k+ rig go up in flames then thought they may have fixed the problem so started to consider it again for another build this puts me off.

[@ruffriki3264]

It’s a pleasure to watch and learn. Thank you!

[@markmmm1737]

I'm not an expert but I am pretty sure that the brakes on a brushless system isn't the same as as accelerating. The motor isn't trying to fight the forward momentum by tring to reverse and causing loads of heat and amps. It (i think) turns the motor into an alternator and so has massive resistance and actually puts charge back into the batteries. Castle cremations im sure didn't get their name by accident lol.

[@richduperbash2966]

Ohhh damn 👀. Always sorry to see smoke. Props to you for standing behind your builds, regardless of what actually went wrong. That Big Girl must be smooth as silk belt driven and sensored. 🍻

[@teslacybertruck750]

0:45 I've seen that man on other videos, I believe one of his RCs hit 180mph. I love that man's attitude.

[@DoRC]

The manual says controller and motor are designed for two 2s batteries in series only. That makes it sound like they're talking about a specific motor and controller not necessarily what you put in there. Looking on their website it appears as though this usually comes with a fairly small motor and ESC. It's a decent sized car to be sure but I have a hard time believing that it is too much weight for an XLX2 to handle. Surely it doesn't weigh more than a fully loaded outcast 8s and they run in those all the time. I think there's something else going on. I highly doubt the ESC was being overloaded. I would get with Castle on this and try and get a replacement. These XLX2 ESCs are kind of known for spontaneously combusting.

[@poohtoo33]

It’s either a bad ESC or wire connection between the ESC and the batteries. If anything between the two aren’t super tight beforehand and come loss during bashing sparks or fire can start at that connection point.

[@xibidit]

what do you mean with the hobbywing esc giving less top speed? it's the batteries that decide how fast you will go, the motor pulls power, the esc does not push power. if settings are maxed out there is 100% of the batteries power going to the motor, there cant be 120% of the power going to the motor just because you have your favorite on off switch.

[@BasedF-15Pilot]

Who makes the chassis? I must have missed it amongst the crazy music.

[@lifeofdave1237]

A lovely build that , shame about the ESC woofing up in smoke, but great seeing you take it on the Chin and replace the faulty unit 👌

[@rotauq]

Must have been bad luck on the ESC. I recently converted my FG marder to 4WD and swapped the MAX5 for a XLX2. Running 8S with a SSS 5694-1000KV, so basically the same setup. It's geared a little lower at 16/46 and 20*/48, but slightly larger wheels. Ran 8 packs so far, mostly parkinglot drifting and never seen more than 120A peaks in the logs. It's heavy but when you're not hitting 100+mph it's shouldn't be pulling high enough amps to destroy it during braking.

[@lexsteel12]

Maybe if you send the ESC back to Castle, they can perhaps get into the data logs with their equipment? And give you more details on exactly what happened?

[@xXB.FunkXx]

Raz do you have a financial reason not to blame the xlx2 for these fires or do you really think that the chance you take puting one in is worth it because they are that much better than say a max 4? No disrespect just a honest question.

[@arnerrvik7586]

[@Basherqueen]

Hi Raz 🖐️🥰. Nice Clean build from you as always 💪 If my calculations are not totally off, then there was nothing wrong with your setup and gearing if top end is of about 50mph. 💪 Also I am quite 100% positive that the brake rate/gearing/weight of the car should not have exceed any of the known limitations of the XLX2. Not even close. The binding drivetrain isn't helping but what is it compared to any off road rolling resident? Just bad luck and bad ESC? Don't blame me but I personally wouldn't change anything except freeing up the drivetrain and give it another go. 😘😘😘

[@brentrobinson3274]

Thanks for the video I never took into account the braking on my baja 5b guess I'm gonna get that on there before running it also can you turn the braking feature off on the xlx2???

[@jaymitchrc]

Also something else to keep in mind, if you're running sensored, if you have to reverse direction of motor it hast to be done within castle link and not by switching motor wires. This was the first thing I actually thought about when I watched this. Also you could consider just not running it sensored at all.

[@DoRC]

The car wouldn't even move if you tried to reverse it by switching motor wires.

[@jaymitchrc]

@@DoRC if you run it using the Sensored wires and reverse wires...you confuse the esc and would blow the esc. You have to leave wires plugged up aa by cc and would need to reverse setting in esc if motor wasn't going in the correct direction.

[@DoRC]

@@jaymitchrc right that's what I was saying. If you don't have the wires in the right order on a sensored setup the motor isn't even going to spin.

[@davidchennellsjr.6799]

[@kollinborn930]

I had this exact same thing happen to my Kraton 1/5 EXB with that same setup, castle warrantied the esc and I’ve had no issues since. I believe it was one out of the “old batch” and no fault of yours

[@toysforboysrc]

Castle ADVISES to STOP the use of 2000kv motor or HIGHER due to the different types of wiring DELTA AND WYE. I’m not a pro by any means, this should been updated firmware already but… whoooo knows man. If this car weighs as much as the 1/5 Kraton then it should be geared like we do with Kraton and I’d never put a 2250kv or what not in a Kraton I’d not go higher than 800-1100 kv’s… I LOVED that bmw it’s a BEAUTY thanks for having it on your channel!!!! PLEASE show more of this car or share link of owners videos!! It drives soooo well it’s almost perfect!

Raz honestly that was a nice happy time when the customer was receiving his car, but so sad that all did not go well as the car caught fire during testing and it really beats my understanding how a drive train design can cause a car to burn the ESC.

[@Techie_ASMR]

As much as i love Raz and his videos.. i gotta agree and say this HW max5 would have been a great choice for this one. as far as I know.. this is not a competition car. it s for a customer. so reliability matters. and we rarely see a HW ESC blows up. customer may not know all the technical details like Raz knows. customer may not need to all the nerdy details and data logging.. but reliability and being able to push anyway you want without having a fear of catching on fire matters.. so HW would have been a great choice. or as we see. XLX2 that is tamed to 70% power would be ok too.

I don’t know what castle motor you were using….but for some reason…that esc doesn’t like the 1100kv motors. The leopard even though it is a 1050kv has a lower amp rating than the castle 1100kv.
