Is a blown BEC one of the most common failure modes on Hobbywings?

I have had 4 blow in the last month. All on three different cars, with different motors, and different settings. Ironically, my one surviving Hobbywing ESC, is the only one running a 7.4v BEC, and its the oldest of the group. Go figure. And the last one, on my 21.5 car, lasted for all of 2 weeks worth of club racing before it expired.

Needless to say, these will not be replaced with another Hobbywing. Because 3 other people at the track have suffered similar issues with the BEC failing right in the middle of a lap.
At the very least, it is very frustrating, and at most, a lot of wasted money. Hobbywings customer support for warranty issues is all but nonexistent. I will never get any of these ESC's replaced under their so called "warranty."

There has to be something environmental going on for that many failures in quick succession. I've never seen a Hobbywing BEC fail and it's the most popular brand at my local tracks.

What model ESCs have failed? On or off-road? Were any servos being overloaded with their end points trying to push past travel limiters? Any cooling fans failed while plugged into the BEC? Anything else connected that could possibly lead to a short?

Yeah, it truly is bizarre. I makes me wonder if there was a bad batch of FET's that made it through due to component shortages, or something similar? (I work for an ISP, and we have had all sorts of issues with hardware over the last year having some seriously questionable QC, and failures of individual components, such a networking adapters in modems, because the manufacturer just took what was available that SHOULD have been equivalent to what they had previously, but turned out to be duds, we have been through several rounds of this in the last year and a half with various end user and infrastructure equipment.)

All of these cars are Off-Road. There is nothing plugged into the BEC of any of them. But connecting the program card to the ESC produces absolutely nothing. And neither the Receiver or the Transponder activate with the ESC powered on.

I have been through 2 Pro Stock Spec ESC's on my 21.5 car, which is a B6.4 running a Muchmore 21.5 with fixed spec gearing for the 21.5 class at HobbyAction, and is no where near being overgeared.
Battery is a Protek 5500 LiPo. Receiver is a genuine Sanwa RX-482 with an RC4 Pro Transponder. The servo is a Pro Performance XTS600, running in SSR mode. BEC is set to 6.0V. ESC settings were 12k drive frequency, with throttle rate set to 20, and braking frequency set to 2k. Everything else was default Blinky Mode settings. Voltage cut off disabled, auto off disabled, all thermal cut off settings left at default. Motor cooling fan is hardwired to the battery terminals, no ESC fan.

The first ESC on the 21.5 went out mid air on a double roller. Car landed, and lazily turned into the pipe with no power. That was only 2 minutes into the heat.
Replaced the ESC that day, and I got three race weeks out of the new one before the exact same thing happened again.
This time though, there was mild contact with another car. Though, I am not sure if the collision happened and the car died. Or the car died, and that caused the collision. But the impact was certainly no where near hard enough to cause any damage to anything, let alone even leave a scuff mark on the lexan. This was less than a minute into the heat, and was 1/3 of the way in on lap 3, under partial throttle on a short shoot leading to a single roller.

Now, with the replacement of the first ESC, I also replaced the non-polarity cap (i always run higher capacity non polarity caps). Just so there was no shared electrical components between the two ESC's.
The servo has tested fine, I have my end points set properly, and there is no strain at the end point limits. I am also running the servo speed at -30 on the radio to help calm it down a little bit. Hence why I am also only running a 6.0V BEC.

My 22X-4 was running an older XR10 Pro, with a Muchmore 13.5. This ESC i originally bought two years ago at OCRC when my first Pro Stock Spec also took a dump in the middle of the XAct RC 10k race. But that was on my 2WD 22 5.0 Elite which was box stock at the time, with a 17.5 Trinity, and the "older" Pro Performance LP10HV-SR servo, and i only ran it in that car for about a month, before i replaced it with another Stock Spec for weight.
The 4WD currently running the XR10 Pro has the same Pro Performance XTS600 servo as my B6.4, same genuine RX-493, same RC4 Pro transponder, with a Protek 6400 LiHV. The ESC is the only non-new part on that car electronics wise. The motor cooling fan is hardwired to the battery leads at the ESC on the new Elite Fan Mount, the stock ESC fan is in place as it was out of the box. Thankfully that ESC's BEC decided to stop working off track. After a diff service, I went to go run some laps up and down my block to test things, plugged the car in, tested the throttle, walked outside, put the car on my driveway, and...nothing. So at least i didnt pay for races I couldnt run. And thankfully i was planning on putting up the 4WD and focusing on 2WD for a while anyway. So, no harm no foul there. But it seemed odd all the same. Nothing was hot, voltage wasnt low, nothing was under strain, it just stopped. This happened a week before the first failure on my 21.5, and I had no problems with that ESC prior to that whatsoever. I chalked it up to a fluke...then the 21.5 BEC failed. ESC settings on the 4WD were throttle rate was set to 25, 8k drive frequency, 1k brake frequency, BEC was set to 7.4v, with no voltage cut off, no auto off, thermal cut off at default, and all other settings left default and blinky mode.

Then my son's 22 5.0 Race Roller also had a BEC take a dive. He is running a Spektrum SR315 receiver, with a Pro Stock Spec ESC that was bought just a little over 6 months ago. He is running a Protek 160TBL servo, with an RC4 Pro transponder, and a Spektrum 5500 LiPo, with the HobbyWing Handout Spec Fixed Timing 17.5 motor we have here at Hobby Action that is so under geared its hilarious. His motor is set VERY soft. His drive is set to 16k, the throttle rate to 0, and his radio is set to 65%-75% throttle depending on track conditions. All other settings are at default except for Auto Off, because screw that "feature". Granted, his car takes a massive beating being in Novice. So i expect some failures. But this too was also a BEC failure, and happened right at the end of his main. Car just stopped responding mid straight. Thought it was maybe a false positive voltage reading, but no, it was a BEC failure. And his car is the most different of all my cars.

Ironically, my oldest surviving HobbyWing ESC is the Pro Stock Spec inside my 22 5.0 Elite. It is at least a year and a half older than all of these other ESC's, and was bought at TRCR when i still lived in Washington, just after i got back from the Xact race at OCRC. It has run a 17.5 Trinity, a 21.5 Muchmore, and is currently running the Hand Out Spec 17.5 Hobbywing Fixed Timing Motor. As i said above it is running the older Pro Performance LP10HV-SR Servo in SSR mode, on a genuine Sanwa RX-483 receiver, and a Protek 4800 LiHV. BEC is at 7.4v, drive frequency is 8-12k depending on track conditions, throttle rate at 20-25 depending on conditions, brake rate set to 2k, and all of the thermal and voltage cut offs are disabled, along with auto off. And it is an absolute champ. It hasnt given me any concerns at all wahtsoever. Granted, neither did the XR10 Pro. But i find it ironic that the most used ESC of the bunch is also the most reliable, and running in what is the most modified of my cars.

Most of my cars have been gone over by nearly ever pro guy there at the track, and they are all as confused about the situation as I am.

At this rate, i am beginning to think i might just be cursed. LOL!
Either way, i only have one car that i can run for the rest of the year, because i am not plopping down that much money to replace ESC's right before Christmas, and after having jsust replaced another one last month. The current track layout being crap, in my worthless non mod running opinion, also makes it an easy decision to not run. At least my son can still run, and he is happy to be on track, so thats all that really matters at this point.

Hello, I am using the XR10 Pro Stock v4 esc. When programming, the choices for throttle curve are 1) linear, and 2) customized. If you choose customized, how do you then do the customizing?
I tried connecting it to PC to use the HW link software but that doesn't seem to allow the options either...

It is EXPO in your ESC + or - with OTA programmer and phone app you can draw your own lines.

recently purchased the OTA module after many years of using the programming box that has been wonderful up until recently (won't connect to 1 of 3 esc's)

Was wondering if after making changes to the esc parameters, do i need to press save towards the top of the screen or are the changes automatically saved?

thanks

You need to press save.

Just wondering... instead of going online, visit to rctech, type the question and wait for an answer, wouldn't it have gone much faster by simply trying for yourself? Change a value, do not press save, disconnect, and then reconnect and see if the change was saved?

Is it ok to not run a capacitor on an xr10 stock spec? 17.5 2wd on carpet… if advised to run one anybody run the stock non polarity one?

great observation, I can answer that 2 ways
  1. After watching a video produced by Charlie, he does not mention pressing the save icon(tab) after making changes or making a profile
  2. I had not received the OTA device, waiting on delivery, and was looking for an answer instead of asking in the comment section of the youtube video

Commenting on the video makes more sense, since that's where you were getting your (mis?)information from.
