Hobbywing V4 130A Shutdown issue

[Comprex]

Hi,

So I'm having an issue here with a Hobbywing V4 130A (both from SAB Italy).

Me and a mate bought a Goblin BlackThunder. He fitted a Pyro 750-560KV and I'm using a Scorpion 4525-520KV 23Pinion. Both equipped with a Hobbywing V4 130A with internal BEC.

Whilst doing our initial flights both ESC's failed and shut themselfs down.

The one on the Pyro said it pulled 190A without blades, which seems kinda high. During the initial flight it pulled 300A which again seems unbelieveable.

The one mounted with the Scorpion went into Error mode and was thus unable to read the logs from this one. When testing afterwards it also said it was pulling 190A without blades. My VBar current/voltage sensor read out 9.9A however which seems more accurate?

Anyone else having this issue or is familiar with this?

Sincerely,
Comprex

Yes, disable lvc and run timing at 15 degrees or higher. The amp reading are also incorrect. Mine always reads over 300. I've had over 30 flights now with no issues on a protos max with 4530 pushing it hard. Check out the thread in the protos max forum about the hw130. If you are at low timing, it might be the cause

According to reports in the MSH forums, the shutdowns are due to the esc timing. There have been issues with around 5 degrees timing, whereas higher timings like 15 degrees have no issues.

Edit: Lol simul-post.

We still aren't positive about the timing issue, but it's looking pretty consistent. Lvc is also a possible factor since the hw logging shows a minimum voltage much lower than it should. Try the timing and disable lvc

Dont pay any attention to the logs you pull from the program box. I was told today these are RAW peak amp draw instead of peak amp spikes. Not completely sure what the first really means unless its an accumulation of current draw over the duration of the flight.
You Vbar log is most accurate.

Two shutdowns on two separate escs is VERY unlikely but still possible no matter how minuscule. That said, what connectors are you using? Also check the solder joints in the battery and well as the esc. Both motor and battery sides.

It was a slow down cut off or a hard one?

I have had similar issues with the 130HV with Scorpion 4526-520 F3C version. Disabled LVC, changed timing to 15 degrees, still get a random shutdown every 4-5 flights. It isnt a shut off but a huge drop in head speed and then it tries to ramp back up then down again, etc, etc.

All solder joints check out. Tested for heat at all connections. Just seems to be fine for some flights then the issue appears again.

The only thing left I am going to change is from ELF Gov to Gov Store. I cant see that being an issue but you never know.

I also have seen LV of 36v when the packs test right after a perfect flight at 3.75v per cell. Amp peaks of 380. I am not that heavy on the sticks.

I will test some more but if I see another issue again I will be sending it in. I have been trying to exhaust all possibilities before I make that call.

If you're checking the peak amps off the program box they aren't correct so 328 is definitely wrong.
If your packs sag this will cause that drop in ELF mode. Gov Store should work better but watch the flight times

same issue here with a Pyro 750-52 (once)
had a hard shutdown right after takeoff doing a nose flip.
factory settings - ELF governer Store.
Maybee the ESC needs some fine tuning for the P750? if I remember right, kontronik had some issues with the P750 and the Jive 120HV also some days ago.

Gov store or gov elf?

sorry, I meant gov store

That's a 14 pole motor

Well it appears I found my issue. I am a donkey. Set screws for the motor can were gone. Lol! Problem progressed to the point I couldn't fly. Grabed the main gear and spun it while holding the motor can. Shaft was still spinning. I still find it weird that the problem was intermittent but I believe the set screw of the flat spot let go first. Then the other was holding just enough but slipped every once in a while until it let go. I had previously checked the set screws but they were there and by hand I could spin the can. Just another thing to check periodically. Lucky I didn't ever crash the heli.

So far 5 flights and no issues what so ever. Fingers still crossed though.

I had this same thing happen to me yesterday on my Gaui R5.


Details:

HW160Av4.
Motor is a KDE700xf-535
Motor shut down, mid flight.
The heli was veryfar away when it happened, so

• HW160Av4
• Motor is a KDE700xf-535
• LVC cutoff set to default of soft
• LVC setup voltage at default of 3.0v/cell
• timing is at the default value of 15
• Only motor shut down, mid flight
• The heli was very far away when it happened, so it is very hard for me to say if it was a soft or hard cutoff. I chose to auto immediately.
• Unfortunately, I did not have my prog box at the field to check for "logging" data.
• Jeti telem says my lowest pack voltage only dipped to 3.5v/cell
• I got no voltage alarms, or activation of my R2 buffer, which tells me the HW BEC was still functioning fine
• Jeti telem shows max Amps pulled in the flight was like 65A

I cannot find any other issues. At this point, I believe that the voltage sensor in the HW is garbage and incorrectly gave me an LVC shutdown.

I have now disabled the LVC cutoff.

After speaking with Rob (KiloXray) yesterday, I believe I still may have had some shut downs in the beginning. After changing some settings as suggested I believe my issue was likely solved. Just coincidence that later I had the set screws let go. I have come to this conclusion because the first couple times it happened I wasn't able to connect the program box like others have reported. Good catch Rob. Every time it happened after changing some settings I was always able to connect the program box. Also there was a progressively worsening sound of the shaft slipping in the motor can.

I hope you have better luck with the setting changes Rob. You weren't even close to pushing the R5. Just putting around really. Nice auto too. He was out there guys. I never would have made it back.

I also had a failure using the Align 130A version of the Hobbywing V4.
Using a Pyro 750-450 motor. Started with timing set a 10 degrees. After a 10 second hover the ESC shut down. LED on the ESC was blue.
Reset timing to 5 degrees. This time ESC shut down after a 15 second hover.
Reset timing to 15 degrees. After a 10 second hover, the ESC caught fire.

[velocity90]

Not dealing well with 14 pole motors?

[UPSDOC]

I have just ordered a new Hobbywing 160A V4 ESC from Hobbywing NA to replace the failed Align 130 Amp ESC. I will be using this with my Pyro 750-450 motor.
What is the recommended safe timing setting for this combination. Just want to make sure that it doesn't end in another ESC fire.

I also disabled the LVC on my Logo 600 with HW130A. before sometimes the headspeed dropped. Now not any more.

have any of these issues been solved, been reading a lot on the 130hv and see a lot of problems with it. i was going to buy one and came here to have a look first. but i see a lot of problems with it. was going to run one in a goblin 570 on 6s for now until i upgrade it to 12s also need to look how much room there is on the 570 for it. thanks
