if you aren't losing power to the servo, check your sensor cable and all your solder joints going to and from the motor. I would swap out sensor wires just to rule that out.

not sure this will help, but I had the same issue with rebooting. After a while I found out that my wire inside the silicone jacket has frayed its self almost all the way through. because it was not visible, I didnt notice it right away. But when I flexed the wire there was almost no resistance. It never cogged though. Cogging seems liek it would be a sensor board or wire issue. But the vtx10 does not support sensorless mode, so if the sensor wire breaks, it normally wont work at all. @ weeks ago, I noticed my vtx10 was cogging really bad and making a god awful noise. Upon further inspection, I saw that one of my sensor wires broke and was making sporadic contact with the connection. I replaced the sensor wire and it was all happy again.


Side not, I am replacing sensor wires like crazy. I have tried the soft super flex, the flat ribbon style and the stiffer wire with pvc shields and none last as long as I would like. I secure them to keep them from flopping around, but its still an issue. Thoughts?

maybe cogging is the wrong word. At first I thought something blew in the tranny just because it was making a strange sound and was hesitating. But after a few seconds it would be good again. I will check the sensor wire the next time I run it

mine was making an awful sound. It sound like my diff was coming apart. But it was just the sensor wire and it never got better, lol.

Tony, lower the LVC back down. Your too high. It may should like a good idea, but the cut off actually happens to start before you get to that number. The system takes power from the motor to compensate for the spike and it cause the motor to "chug". Lower the LVC put off number, you can technically go a little lower, because that kick in will happen about 6.4 giving you time to stop, if you even get to run close to it.

Nikos2002,
This is exactly my problem also...to the letter. I have the viper/copperhead 4500 combo. Sensorless so the wire isn't the problem. You turn it off then on and its fine. No wiggling wires, or touching anything but the switch.
I ran three heat races this last Saturday and had a shutdown in each race.
I just loaded up and took my junk home...lol
Do you have any updated info on this problem?
Thanks

out of curiosity, do you have the radio set up on the high speed settings? If so, try turning that off. I know one of the other guys was running the 4pk with the high speed settings and it acted goofy like this. He got an M12 and same thing. It's something in the way the radio works with that super high speed setting.

I had that on my Viper Copperhead and found that my banana plugs (the cheap ones) were not making a good connection. I went to the better plugs and have not had that problem since.

Graveyard - PM your settings from the ProGauge/EZ Link.

The Copperhead system is high draw 4 pole system. Its a monster - you even hear it when it starts up!!! If you have a loose bullet connector like meyankee said, that could cause a cut off. Depending on the strength on your battery, that could cause a cut off. So there are a few variables involved.

But send me your settings, we can work with them as well.

I don't have a pro gauge/EZ link. I have had the esc set on #4 factory setting.
I don't know guys...the wires seem tight and I have everything with a small amount of slack. Nothing binding or anything. As far as the batteries, each time last Saturday was with a different battery.

Also, what is the high speed setting on the radio? I'm using a spektrum dx3s with a telemetry rx.
Thanks

Hi Bob, thanks for the reply...
What are these settings your speaking of? I'm using a spektrum dx3s and a 3100 rx I think. The one with telemetry ,although I haven't been using the
telemetry part .

without the progauge - drop down to profile 3 to see if you have the same effect.

ok, I will try it but if that doesn't do it, what is my next move? This is a strange problem because when it happens, I still have steering...just no throttle until it is shut off and then back on.
Later

I'm not too familiar with that particular radio, but on the Futaba and Airtronics radios, there is a Super High Speed Response setting. They all call it something different. Basically when you have it turned on and use compatible receivers and servos, you get ludicrous speed (gratuitous Spaceballs reference ).
